Parts Of A Car And Their Functions

Cars contain many systems—from the engine to the brakes—that work together to get you down the road safely and comfortably. And each of these systems is made up of many different components.

Whether you plan on working on your car yourself or taking it to a repair shop, it’s helpful to be familiar with the fundamental automotive systems and parts listed below.

#1. Engine.

An internal combustion engine is the heart of the car. Simply put, it’s a container that converts fuel into energy, which powers the vehicle. Fuel is introduced into the combustion chamber and ignited by spark plugs. (Diesel engines don’t use spark plugs)

This results in an explosion that makes the pistons move. The pistons cause the crankshaft to rotate, which powers the wheels via the transmission.

However, the engine is dependent on other components, like the alternator, radiator, and fuel system, for smooth operation.

We’ll cover these areas below. Importantly, when a check engine light comes on (a common warning sign), the problem often doesn’t involve the engine itself but one of these supporting systems.

Be observant of any unusual sounds or smells coming from the engine compartment as another indicator of trouble.

#2. Battery And Alternator.

The battery stores energy in chemical form so it can be released as electricity to run your vehicle’s electrical components. Other terms you may run into when talking about a car battery are:

• Battery Terminal: A means of connecting the battery to the vehicle’s electrical system. The three types of battery terminals are post or top, side, and L.
• Battery Capacity: The energy output of a battery measured in amp/hours.
• Cold Cranking Amps: Abbreviated CCA, this refers to the amount of current that the battery can supply to the vehicle.
• Group Size: The group size is just what it sounds like, the size of the battery. Common group sizes are: 24, 24F, 25, 34, 35, 51, 51R, 52, 58, 58R, 59, 65.
• AGM: This stands for absorbent glass mat, a design in which sulfuric acid is absorbed by a fiberglass mat, making the battery spill-proof and better at holding a charge.

The alternator is an electricity-generating device that converts mechanical energy to electrical energy in the form of alternating current. It is used to supply power to your vehicle’s electrical system along with the battery.

The alternator also recharges the battery using mechanical energy generated by the motion of the vehicle’s parts.

#3. Transmission.

While most automobiles sold now have an automatic transmission, you’ll still find manual transmissions in sports cars and some economy vehicles. Both of these gearboxes do the same thing, transfer power from the engine to the wheels.

An automatic transmission uses a complex series of gears, bands, and other parts to manage the engine’s power as the vehicle’s speed and torque change.

It’s all handled through a driver-selectable gear lever controlled mainly by a computer. On the other hand, a manual transmission relies on a clutch to connect and disconnect the transmission from the engine.

The driver uses a lever each time there’s a need for a different speed and torque.Look for sluggish performance, difficult gear changes, and strange sounds underneath the car as signs of a transmission problem.

#4. Radiator.

The radiator is a core part of a car’s cooling system and is typically located at the front end, behind the grille.

A radiator can be aluminum or plastic and draws excess heat away from the engine through a network of tubes next to the engine block and cylinder heads.

Coolant circulates through the system, pulling heat from the powerplant and becoming cool again as it passes through the fins inside the radiator.

Radiator troubles often begin as a coolant leak visible underneath the car. A temperature warning light can also indicate problems with the radiator or cooling system.

It’s important to remember that coolant is toxic (so keep children and pets away from leaks), and a radiator should never be opened when hot (pressure can spray scalding coolant).

#5. Front Axles.

Front Axles are sturdy shafts fixed to the wheels on both ends that transfer torque from the drivetrain to enable wheel rotation.

Axles must bear the vehicle’s weight and force during acceleration, braking and turning. They allow differences in left and right wheel speeds when cornering and accommodate suspension travel.

#6. Rear axles.

The rear axle plays a major role between the driving wheels and the differential. It distributes power between the two rear wheels.

The rear axle consists of two components known as half shafts. Both axles connect to the differentials from the opposite wheels. Most rear axles spin with the vehicle wheels.

#7. Brakes System.

Brake Pads and Rotors

When the driver applies the brakes, the brake pads, typically made of friction materials like ceramic or composite, clamp onto the brake rotors, which are metal discs connected to the wheel hub.

The friction generated between the pads and rotors converts kinetic energy into heat, slowing the vehicle down. This design ensures effective and controlled braking, with regular maintenance required to ensure optimal performance and safety.

Brake Calipers and Master Cylinder

Brake calipers are essentially hydraulic clamps. When the driver activates the brakes, brake fluid pressure forces the caliper’s pistons to squeeze the brake pads against the rotor, creating friction and slowing down the vehicle.

It creates precise and controlled braking, converting kinetic energy into heat and stopping the vehicle safely.

A master cylinder consists of a cylindrical chamber and piston assembly. When the driver applies the brake pedal, it displaces the piston, pressurizing brake fluid within the chamber.

This hydraulic pressure is transmitted through brake lines to the calipers, initiating the braking process by forcing the brake pads against the rotors, slowing the vehicle down safely and effectively.

Brake Lines and ABS Module

Brake lines are typically made of steel or flexible rubber and are essential for transmitting brake fluid from the master cylinder to the brake calipers or wheel cylinders.

When the driver applies the brakes, hydraulic pressure within the lines ensures that this force is evenly distributed to all four wheels, allowing for controlled and balanced braking, contributing to the vehicle’s safety and stability.

The Anti-Lock Braking System (ABS) module monitors the speed of each wheel. When wheel lockup is detected during hard braking or slippery surfaces, the module momentarily releases and reapplies brake pressure, preventing skidding.

This design ensures stable, controlled stops on slippery surfaces, enhancing driver safety.

#8. Catalytic Converter.

When your car is running, it generates fumes and gases called emissions. To help regulate emissions and remove them from your car efficiently, there is an exhaust system hard at work. One of the main components in this system is the catalytic converter.

The catalytic converter helps change harmful compounds in emissions into safe gases before they’re released into the air through your tailpipe. Issues with the catalytic converter can cause a drop in performance and fuel efficiency.

#9. Muffler And Resonator.

The muffler and resonator collaborate in a car’s exhaust system to keep noise levels correct. The muffler’s main job is to reduce noise, while the resonator fine-tunes sound frequencies, adjusting the exhaust notes.

When a driver can hear how the car is running, they’re able to drive more adaptively and enjoy a pleasant driving noise.

#10. Tailpipe.

A tailpipe is at the rare end of an exhaust system. It is used to expel exhaust byproducts into the atmosphere. Exhaust pipes link several exhaust components together.

They can damage because of broken brackets, corrosion from age, and failed seals.

#11. Fuel Tank.

The fuel tank stores the vehicle’s fuel. It is designed to be durable and leak-proof, ensuring a safe supply of fuel to the engine.

• Stores vehicle fuel
• Durable and leak-proof
• Ensures safe fuel supply

#12. Cooling System.

The engine’s temperature is controlled by the cooling system, which also guards against overheating and minimizes wear and tear.

The radiator circulates coolant throughout the engine to perform its function. It also includes a water pump.

For the cooling system to function at its best, frequent maintenance is necessary to preserve the longevity of the engine.

#13. Serpentine Belt.

A serpentine belt, also known as a multi-rib or poly-v belt, is a drive belt that runs multiple components in a vehicle’s engine. It is usually made of rubber, reinforced with fiberglass cords, and is shaped like a snake, hence the name.

The serpentine belt appears in most cars’ front of the engine block. The belt consists of multiple ribs designed to fit into grooves on the pulleys of the accessories and engine components.

The strap provides a more efficient power transfer from the crankshaft to the features that need to be powered.

The serpentine belt, driven by the crankshaft pulley, is connected to the engine. From there, it wraps around multiple other pulleys that power different components in the engine, such as the alternator, air conditioning compressor, power steering pump, and water pump.

The serpentine belt also helps reduce noise and vibration, allowing for more efficient packaging of parts in the engine compartment.

The belt then wraps around the crankshaft pulley again, completing the route. The belt, designed to reduce wear and tear, ensures that all components receive the proper power.

The serpentine belt employs an automatic tensioner that adjusts for tension changes due to temperature or engine load. The tensioner ensures all parts receive a consistent amount of power, which helps maintain the vehicle’s optimal performance.

A malfunctioning serpentine belt may result from various factors, including a worn belt or dry serpentine belt, a worn-out pulley or wrong pulley alignment, exposure to coolant, cold weather, and a misaligned belt due to improper installation.

#14. Lubrication System.

You probably already know that your car needs engine oil to function properly. You may also know when to check your engine oil, how to top it up, and that it needs changing every once in a while.

But how exactly does the engine lubrication system work? If you’ve ended up here, you’re probably wondering the same thing.

Put simply, it’s the system that ensures oil is distributed to the various lubrication points within the engine.

Lubrication points are the places where engine oil flows between moving parts, reducing friction and cooling vital components.

Both traditional internal combustion engines and electric motors rely on a lubrication system, although there are some key differences.

Most notably, an electric motor has far fewer moving parts than a petrol or diesel engine, and may even have a sealed lubrication system. This means lubricant is applied by the manufacturer and is expected to last for the lifetime of the car.

The following information refers to the components of an engine lubrication system in a traditional petrol or diesel car.

#15. Ignition System.

The ignition system’s job is to ignite the air-fuel mixture in a gasoline engine. In addition to the spark plugs that spark in the combustion chambers, the ignition system consists of an ignition coil, which converts battery voltage to higher voltage, and the spark plug wires that join these components.

Advancements have greatly reduced the need for ignition system service. Where distributor caps and rotors once needed replacement, electronic ignitions typically keep on firing. In new vehicles, spark-plug replacement intervals are often around 100,000 miles.

Spark plug wires still require attention and occasional replacement, though an individual coil-on-plug eliminates those wires entirely.

#16. Power train.

A powertrain is a system inside a vehicle, boat or another type of machinery. The system is designed to propel the vehicle forward. In a car, a powertrain consists of the engine or motor and its internal components, such as the energy storage system, transmission and driveshaft.

In a conventional internal combustion engine (ICE), the powertrain converts the stored gasoline or diesel energy to kinetic energy in the engine and transfers it via the transmission, driveshaft and differential as torque to the wheels of the vehicle, propelling it forward.

The vast majority of powertrain systems in production today are based on ICEs. These can either be spark ignition (SI) in the case of gasoline or compression ignition (CI) for diesel.

Electrification of road vehicles has significantly increased the production of both hybrid engines, which use a mix of ICE and electrified powertrains, and fully electrified systems.

The energy for electrified systems can come from a range of sources, including onboard generation, plug-in charging or even hydrogen fuel cells.

#17. Clutch.

The clutch has a function to transmit the torque from the engine into the drive-train. Basically, the clutch enables smooth vehicle movement by delivering the power from the engine to the drive-train. Also, the clutch reduces drive-related vibrations.

The clutch itself is located on the rear side of the engine and is attached to the flywheel, and the clutch pedal is located on the floor of the car, on the left far side.

It can be found only on cars with manual transmissions. The cars with automatic transmissions have a built-in clutch that is not visible from the cabin. Replacing a clutch can cost anywhere from $1000 to $1400.

There are 9 types of clutches:

• Single plate clutch: Mostly used on modern light vehicles.
• Multi-plate clutch: More clutches mean more friction surface, therefore, more capacity to transmit torque.
• Cone clutch: The friction surfaces are in a shape of a cone(2 of them).
• Centrifugal clutch: Uses centrifugal force to keep the clutches in engaged position.
• Semi-centrifugal clutch: This clutch uses a centrifugal force only to transmit torque at a higher speed engine. For regular speed, the clutch uses levers and clutch springs.
• Dog and spline clutch: The two shafts are locked in with external teeth and sliding sleeves with internal teeth on a so-called ”dog” lock.
• Electromagnetic Clutch: The torque is transmitted mechanically, but the clutch operates electrically.
• Vacuum clutch: This type of clutch uses a vacuum in the engine manifold that operates the clutch.
• Hydraulic clutch: Same as the vacuum clutch. The only difference is that the hydraulic clutch uses oil pressure to operate instead of a vacuum.

#18. Propeller shaft.

This component is located on the rear wheel drive system to support the rear wheel suspension. The following is the function of the propeller shaft that you need to know:

1. Connecting the Rotation of Transmission Towards Axle

There is also a universal joint component on the propeller shaft which functions to balance the car when driving on a bumpy road. This component is one of the components of the powertrain that makes the car have strong power but still comfortable to use.

2. Dampening Excessive Vibration

When the car’s transmission transmits rotation to the axle, it has the potential to produce excessive vibration on the wheels. Now, with the propeller shaft, the excess vibration can be dampened.

Drivers and passengers will not feel any excessive and disturbing vibrations. Even when the car is going fast, the propeller shaft can still prevent excessive vibrations from appearing in the car.

3. Controlling Distance Changes

The propeller shaft also functions to control distance changes. When the car is running, the distance between the transmission and the axle can change. Even so, with the propeller shaft, these changes can still be controlled properly.

#19. Differential.

Every engine serves a purpose to keep it moving while on the road. The differential is a key component in a car that helps deliver torque to the drive wheels while allowing them to turn at different speeds during a turn.

Whether the car is front-wheel drive, rear-wheel drive or all-wheel drive, the differential is necessary.

What does a differential do? The differential is a system that allows the drive wheels to turn at different speeds, which is required when the car is negotiating a turn. In a turn, the outside wheel must travel farther, which means it must rotate faster than the inside wheels.

The differential is made up of various parts, including the ring and pinion gears, spider gears, and side gears.

The location of the differential depends on the drive system of the vehicle, with front-wheel drive vehicles often having a transaxle and rear-wheel drive vehicles having a separate rear differential.

There are different types of differentials, including open differentials, limited-slip differentials, locking differentials, and torque-vectoring differentials, each with its own advantages and uses.

Signs of a worn-out differential include driveline noise and vibrations, grinding or clunking sounds, strange sounds when turning, whining or whirring sounds and oil leaks.

Keep reading to learn more about the different kinds of differential systems and why they’re important.

#20. Timing Belt.

Timing belt is a reinforced rubber band that has a main function to connect the engine crankshaft to the camshaft in such a precise order that each time the car starts running.

The timing belt is set in motion and it will turn the camshaft which will open and close the engine valve’s allowing the pistons to move up and down. This is a very precise operation and there is no room for error.

If your timing belt starts producing squeaking noises, it is definitely time to change it. A brand new belt costs between $500 to $900. But, if not changed on time, it can break and cause damage that will cost you up to $2000.

The timing belt comes in metric and imperial dimensions. Check your manufacturer manual to see which size timing belt your car is using.

#21. Suspension and Steering.

Shock Absorbers and Struts

Shocks and struts are essential components of a vehicle’s suspension system, designed to manage ride comfort and stability. Shocks typically consist of a cylinder containing hydraulic fluid with a piston rod inside. Struts combine the shock absorber with a coil spring.

When a vehicle encounters bumps or irregularities in the road, the shocks and struts dampen the resulting vertical motion by forcing the hydraulic fluid through small passages.

This hydraulic resistance converts kinetic energy into heat, effectively reducing the impact felt by the vehicle and its occupants.

Properly designed shocks and struts ensure a smoother, more controlled, and comfortable ride, enhancing overall vehicle handling and safety.

Control Arms and Bushings

Control arms, typically shaped like a wishbone, connect the wheel assembly to the vehicle’s chassis at two points for rigid positioning within the wheel well.

A ball joint attaches the steering knuckle to the chassis, maintaining the wheel’s vertical position while going over bumps and dips.

Bushings, made of rubber or polyurethane, sit within control arm mounting points and isolate them from vibrations.

They allow controlled movement while minimizing road-induced shocks, ensuring stability, precise steering, and ride comfort.

Power Steering Pump and Rack

A power steering pump is designed with a rotary vane or gear mechanism and is typically driven by the engine’s serpentine belt.

When the driver turns the steering wheel, the pump pressurizes hydraulic fluid, creating force to assist in turning the wheels. This design enhances steering ease and responsiveness, especially at low speeds and during parking maneuvers.

A power steering gear, also known as a steering rack, contains a set of gears and a rack and pinion mechanism.

When the driver turns the steering wheel, the gear converts this rotational motion into linear motion, transferring it to the wheels through tie rods.

Hydraulic pressure from the power steering pump assists this process, making steering smoother and more manageable. This design enhances driver control and reduces steering effort, particularly in tight maneuvers.

#22. Shock Absorber.

Shock absorbers are an integral part of a vehicle’s suspension. A shock absorber is designed to absorb or dampen the compression and rebound of the springs and suspension.

They control the unwanted and excess spring motion. Shock absorbers keep your tires in contact with the road at all times. Before going any further, let’s discuss some key terms that will help us understand how shock absorbers work.

Back in elementary school we learned about energy, more specifically, we learned about potential and kinetic energy. We also learned about the Law of Conservation of Energy.

The Law of Conservation of Energy states that energy cannot be created or destroyed, it can only change forms. Potential energy is stored energy and kinetic energy is energy in motion.

Now, let’s get back to shock absorbers. When you hit any bump or dip in a road, your vehicle’s suspension and springs move so the tire can stay in contact with the road and absorb the energy.

The shock absorbers dampen the movement of the springs by converting the spring’s kinetic energy into thermal (heat) energy. This thermal energy is then degenerated in hydraulic fluid.Shock absorbers are an oil-filled cylinder.

When your vehicle’s suspension moves, a piston moves up and down through the oil-filled cylinder. The up-and-down movement of the piston forces small amounts of fluid through orifices (tiny holes) in the piston head.

Since only a small amount of fluid is forced out, this slows down the suspension’s movement and dampens the compression and rebound of the springs.

Shock absorbers are also velocity-sensitive. This means that the faster the springs are moving, the more resistance the shock absorber provides.

#23. Gear Box (Transmission).

The Gear Box, or transmission, also referred to as a car’s Power Train, comes in at a close second to the engine. This part is what commonly needs attention when vehicles fail. The gearbox, when restored, can give new life to even the oldest of vehicles.

The transmission is what contains the different gears that a car needs to shift into depending on speed. These gears transfer the engine’s power to the wheels of the vehicle.

A transmission is available in two types: the manual and the automatic models.

With manual transmissions, the driver selects gears through the use of a shift lever and clutch pedal. Meanwhile, automatic transmissions can shift through forward gears by themselves, and the driver only needs to select between drive (forward) and reverse.

Obviously, an automatic transmission is more convenient and is more popular, however, it doesn’t last as long. In addition, some performance enthusiasts argue that you give up control when you opt for an automatic.

Interestingly, many seasoned drivers prefer manual transmission as being more fun to drive.

#24. Exhaust System.

When our engine runs, it creates a lot of toxic gases that are released into the atmosphere. Here is how the exhaust system works and how the gases change from toxic to non-toxic before they exit the tailpipe.

The exhaust is a set of pipes that have a function to transport toxic gasses from the engine through the exhaust system and reaching the tailpipe as a final destination.

From the engine to the tailpipe, the toxic gas will be transformed into non-toxic gas thanks to the catalytic converter and will be released into the atmosphere.

There are many types of exhausts,

• MagnaFlox Exhaust
• Flowmaster American Thunder Exhaust
• Heartthrob Exhaust
• Borla Exhaust
• MBRP Exhaust

#25. O2 Sensor.

When a car’s being driven, it produces waste gases that need to be carried away from the engine. The exhaust system in a vehicle plays a crucial role in managing emissions and expelling fumes.

The oxygen sensor, also known as an O2 sensor, is a key component of the exhaust system that measures the amount of unburned oxygen in the exhaust.

What does the O2 sensor do? The O2 sensor communicates with the vehicle’s electronic control unit (ECU) to determine the optimal air-to-fuel ratio for engine performance.

O2 sensors became mandatory in vehicles in 1981, and many vehicles made after 1996 have multiple oxygen sensors to monitor the catalytic converter.

These components work together to communicate with the fuel injection system to help maintain the performance of the vehicle.

Signs of a failing O2 sensor include decreased gas mileage, engine misfiring, drop in engine power and a rotten egg smell. It is important to have a trained technician diagnose and fix the issue.

Keep reading to find out more about how the O2 sensor works within the exhaust system and why it’s so important.

#26. Electronic Control Unit.

An electronic control unit (ECU) is a small device inside a vehicle that controls one or several electrical systems in that vehicle. It tells electrical systems what to do and how to operate. ECU’s core is a microcontroller, and it is controlled by embedded software.

How does it work? An electronic control unit receives input from one or several parts of the vehicle and uses that information to take action if needed. For example, an airbag ECU receives information from crash sensors and seat sensors.

When there is a crash, the ECU decides which airbags to deploy depending on where passengers are sitting. Then it tells the actuators to deploy them. Then the actuators convert the electrical signal into the physical value needed, using valves, injectors or relays.

Vehicles may contain over 100 ECUs that in addition to essential functions, like engine performance and power steering, control comfort and security features, such as parking assistance, memory seats, and airbag deployment.

#27. Headlights. 

The car has various components to drive safely –lights are one of them. This component has an important role, especially in supporting low-light driving activities.

Not only do they illuminate dark streets, but the lights also improve visibility when it’s raining heavily to signal other drivers.

A car headlight is mounted on the front of the car to illuminate roads. Because it is on the front, it is often called a headlamp.

In addition, it is often called the headlight -although it is more suitable to call it a headlamp. Meanwhile, the headlight explains more about the beam of light.

#28. Air Filter.

Maintaining the overall health and efficiency of your vehicle requires attention to many small yet crucial components. One often overlooked part is the air filter, a key element that affects everything from engine performance to fuel efficiency.

An air filter might seem like a minor part of your vehicle, but it has a significant job. Its primary function is to clean the air entering your engine, preventing dust, debris, and other contaminants from infiltrating the engine block.

Clean air is vital for the combustion process, where the engine mixes air and fuel to produce power.

Without a proper filter in place, harmful particles can cause damage to the engine’s internal components, leading to wear and tear that could be expensive to repair.

A dirty air filter, on the other hand, restricts airflow, leading to a sluggish engine and reduced performance.

#29. Airbags.

Airbags are inflatable cushions built into a vehicle that protect occupants from hitting the vehicle interior or objects outside the vehicle (for example, other vehicles or trees) during a collision.

The instant a crash begins, sensors start to measure impact severity. If the crash is severe enough, the sensors signal inflators to fill the bags with gas in a fraction of a second.

Airbags don’t typically require maintenance unless they deploy in a crash. In that case, they must be replaced at a repair shop that uses original equipment manufacturer (OEM) replacement parts to ensure that the new airbag is not counterfeit.

Counterfeit airbags may fail to deploy or release metal shrapnel during deployment.

#30. Seat Belt.

Seat belts are essential safety equipment. For drivers and front-seat passengers, using a lap and shoulder belt reduces the risk of fatal injury by 60% in an SUV, van or pickup and by 45% in a car.

Although the vast majority of people buckle up, there are still some who refuse or forget. Nearly half of people who die in crashes are not belted.

Belt laws increase belt use, especially with publicized enforcement.The strongest laws allow for primary enforcement, or for police to stop a driver solely for not using a seat belt.

In states with secondary enforcement, police can only enforce the belt law if they have pulled over the driver for another violation first.

All vehicles have belt reminders, but many aren’t persistent enough. After finding that good reminders increase belt use, IIHS began rating them in 2022.

Worn properly, seat belts are designed to spread crash forces across the stronger bony parts of the body, including the shoulder, rib cage and pelvis.

Seat belts also prevent occupants from being ejected from the vehicle, an event associated with high risk of injury and death.

#31. Taillights. 

Vehicle security arises as a top priority as we negotiate the complicated system of highways and roads. Amongst the many factors that contribute to a vehicle’s general security, the significance of the rear lights is frequently downplayed yet deeply important.

Tail lights are more than just decorative accents to a vehicle; they also play an important function in improving awareness, interaction, and overall safety on the road.

We look into the basic importance of taillights in the larger picture of automobile security in this research, throwing light on how such seemingly tiny parts lead to a better, more secure commute for both drivers and neighbouring road users.

Types Of Tail Lights 

Tail light system development demonstrates a dedication to increasing security precautions and ensuring that cars are fitted with lighting technologies that not only satisfy legal requirements but also improve visibility in general and interaction on the road.

LED Tail Lights

LED tail lights are a significant advancement in vehicle illumination technology. LED lights, as compared to ordinary fluorescent bulbs, produce light via semiconductor diodes, which has several advantages.

One big advantage is conserving energy, as LED lighting demands less power, allowing cars to consume less fuel.

Xeon Tail Lights

Xenon tail lights, additionally referred to as high-intensity discharge (HID) tail lights, are a cutting-edge form of lighting used in automobiles.

Xenon lights create light by a gas release method, and they have various advantages over ordinary halogen lamps.

The illumination and brightness of Xenon tail lights are two of their key advantages, so they produce a brighter, more concentrated light, which improves vision.

Halogen Tail Lights

Halogen tail lamps are a kind of automobile illumination that emits light from halogen lights.

A filament made of tungsten is contained in a tiny transparent plastic envelope that holds halogen gas in halogen lamps. The lamp’s filament burns up and emits light when a current passes through it.

#32. Windshield.

The windshield or windscreen is the front window, which provides visibility while protecting occupants from the elements.

Windshields protect the vehicle’s occupants from wind and flying debris such as dust, insects, and rocks, and provide an aerodynamically formed window towards the front. UV coating may be applied to screen out harmful ultraviolet radiation.

However, this is usually unnecessary since most auto windshields are made from laminated safety glass. The majority of UV-B is absorbed by the glass itself, and any remaining UV-B together with most of the UV-A is absorbed by the PVB bonding layer.

#33. Windshield Wipers.

A windscreen wiper or windshield wiper is a device used to remove rain, snow, ice, washer fluid, water, and/or debris from a vehicle’s front window so the vehicle’s operator can better see what’s ahead of them.

Almost all motor vehicles, including cars, trucks, buses, train locomotives, and watercraft with a cabin, and some aircraft are equipped with one or more such wipers, which are usually a legal requirement.

A wiper generally consists of a metal arm; one end pivots and the other end has a long rubber blade attached to it. The arm is powered by a motor, often an electric motor, although pneumatic power is also used for some vehicles.

#34. Proximity sensors.

A proximity sensor for cars is a tool for identifying nearby items. These sensors operate using an electric signal and can sense an object without making physical contact.

Car sensors warn if someone tries to break into or tamper with a vehicle, commonly used in security systems. Smart keys can unlock doors and help with parking by finding open spots when the owner is nearby.

We utilize these sensors at times to estimate distance and prevent harm to the vehicle, person, or animal.

Proximity refers to the physical closeness of objects or things. A concept often utilized in technology through proximity sensors. Engineers designed these sensors to detect the presence of nearby objects, people, or body parts.

Companies commonly use proximity technology in security, keyless entry, and automated parking systems. It activates actions when something or someone approaches a specific area or entrance.

1. Proximity sensors can sense cars coming and open garage doors automatically. These sensors can also count how many cars enter a garage.
2. They can also detect people or animals approaching your car and trigger an alarm.
3. Unlock your car doors when you are nearby automatically with Proximity sensors.
4. Proximity sensors help cars park by detecting space or when they get close to a wall or another vehicle. Automatic car parking works by detecting and computing distances from the car to the obstruction.
5. Car security systems use sensors to detect if someone is trying to break into or tamper with the car.
6. Proximity Sensors can even be used for electronic hand controls for cars.

The word proximity derives from the Latin proximitas, which means “closeness.” Proximity refers to the physical closeness of two or more things.

Proximity sensors detect the presence of nearby objects in security systems, keyless entry systems, and automated parking systems. Proximity means things near a door, hatch, or a person’s body.

#35. Car Hood.

A car hood, also referred to as a “bonnet” in some countries, is the hinged cover that rests over the engine bay of a front-engine vehicle.

The car hood protects the engine and connected parts from the elements while providing easy access for repairs and maintenance.

Car hoods are typically constructed from steel and sometimes from aluminum. Aftermarket car hoods may be constructed from various other materials, including carbon fiber, fiberglass, or dry carbon.

A concealed latch is typically used to lock the hood in place while driving. A release for the mechanism can be accessed from the dash below the steering wheel. On race cars and vehicles with an aftermarket hood, exposed pins may be used to secure the car hood.

Hoods sometimes contain a hood scoop or a power bulge to allow for greater engine capacity and airflow to increase the car’s performance output.

With the prevalence of electric vehicles, that part of those cars is increasingly referred to as a “frunk,” or front trunk.

#36. Trunk.

A car trunk is an enclosed lockable storage area in a sedan, coupe, or convertible separate from the passenger cabin. The trunk typically sits in the rear of the car in most models.

In cars where the engine is in the middle or rear of the body, the trunk may be at the front. Some models, particularly newer electric vehicles, have two trunk compartments.

While owners commonly use a car trunk for transporting cargo, it can also store other add-ons.

Necessities might include emergency supplies, a spare tire, an onboard tool kit, a lug wrench and jack, fuse boxes, and electronics for video and sound systems.

Convertible cars usually have less usable rear trunk space as the retractable roofs, especially hardtops, are often stored there while in the down position.

#37. Wheels and Tires.

Tire Types and Tread Patterns

Passenger vehicles rely on various tire types and tread patterns to meet specific driving needs. 

• Summer tires, with their smooth and shallow tread, offer excellent traction on dry roads but are less effective in wet or snowy conditions.
• All-season tires feature moderate tread depth, providing a balance of performance in diverse weather.
• Winter tires, designed with deep, aggressive tread patterns and a flexible rubber compound, excel in snow and ice.
• Performance tires prioritize grip and handling, while touring tires emphasize a smooth, comfortable ride.
• Off-road tires or truck tires have rugged, deep treads for adventures on rough terrain.

The choice depends on driving conditions and personal preferences.

Wheel Construction and Alloy vs. Steel

Wheel construction significantly impacts a vehicle’s performance and aesthetics. Wheels can be constructed from steel or lightweight alloys, with designs ranging from simple to intricate.

Alloy wheels are preferred for their reduced weight and enhanced appearance, while steel wheels are more durable and budget friendly.

Wheel design plays a role in vehicle styling, and different wheel sizes can influence handling and ride quality.

Tire Pressure Monitoring System (TPMS)

TPMS keeps you informed about tire pressure, ensuring they remain properly inflated for safety and fuel efficiency, ultimately enhancing the longevity of your tires.

Each tire has a sensor inside, commonly attached to the valve stem, that detects pressure and relays it to a module connected to the vehicle using a radio frequency identification, or RFID.

When the pressure is outside of a predetermined threshold, it triggers a TPMS light on the dash.

#38. Fuel Gauge.

The fuel gauge on your car is what allows you to see how much fuel you have left. It’s an important part of making sure that your car doesn’t suddenly run out of gas, leaving you stranded on the side of a road.

But how exactly do these fuel gauges work, and what components allow them to measure the gas levels in your tank? We’ve taken a closer look at fuel gauges to let you know exactly what’s going on in your car.

Fuel gauges are effectively sensing units for a car. They’re effectively made up of two components: the sensing unit and the indicator.

The sensing unit itself works with the help of a float switch, which is connected to a potentiometer. As the tank empties and the float switch drops, it slides a moving contact along the resistor and creates resistance.

At a certain point, this will also turn on a “low fuel” light on some vehicles. In this particular system, there’s also an indicator unit that measures the amount of electric current flowing through the sensing unit.

When the tank level is high and maximum current is flowing, the indicator points to “F” to indicate a full tank. When the tank is empty and the least current is flowing, then the need points to “E” to show that the tank is empty.

#39. Speedometer.

speedometer, instrument that indicates the speed of a vehicle, usually combined with a device known as an odometer that records the distance traveled.

British inventor Charles Babbage invented an early type of speedometer made for locomotives, though Croation inventor Josip Belušić is credited with inventing the electric speedometer in 1888.

A speedometer indicates speed via a circular permanent magnet that rotates 1,000 revolutions per mile of vehicle travel. This motion is initiated by a flexible shaft driven by gears at the rear of the transmission.

The magnet turns within a movable metal cup made of a light nonmagnetic metal that is attached to the shaft carrying the indicating pointer. The magnetic circuit is completed by a circular stationary field plate surrounding the movable cup.

As the magnet rotates, it exerts a magnetic drag on the movable cup that tends to turn it against the restraint of a spiral spring. The faster the magnet rotates, the greater the pull on the cup and the pointer.

The speed-indicating dial is graduated in either miles per hour or kilometres per hour or, in certain models, both.

The electronic speedometer, a more modern version of the device, works via a rotation sensor mounted in the transmission, and was first introduced in the 1980s.

It displays speed in either the traditional format or as a number on a liquid crystal display (LCD) screen. The rotation sensor delivers pulses that correspond to the rotation of the drive shaft.

This data is then interpreted by the speedometer’s internal computer, which converts rotations into miles or kilometres per hour.

#40. Temperature Gauge.

Your car is a marvelous machine, generating impressive amounts of power to drive you forward. All this hard work generates a lot of heat — it is a combustion engine, after all.

Though your engine was designed to withstand the heat, overheating is still possible and can cause some damage.

That’s why your car’s dashboard includes an engine temperature gauge and/or a warning light to help you monitor the engine’s temperature and notify you when the temperature is out of the safe range.

#41. Fuel Pump.

A car engine burns a mixture of petrol and air. Petrol is pumped along a pipe from the tank and mixed with air in the carburettor , from which the engine sucks in the mixture.

In the fuel-injection system, used on some engines, the petrol and air are mixed in the inlet manifold.

A fuel pump draws petrol out of the tank through a pipe to the carburettor.

The pump may be mechanical worked by the engine – or it may be electric, in which case it is usually next to or even inside the fuel tank.

#42. Odometer.

An automobile’s most prominent yet unexplored part is the odometer. It is placed behind the steering wheel on the dashboard.

It displays the distance the car has run. Odometer readings are beneficial to car owners when selling the vehicle. It helps evaluate the mileage or plans for car service.

Odometers can be mechanical, electrical, or a combination of the two. They are also known as mileometer or milometers in countries with imperial units or US customary units.

Odometer is the most widely used name, especially in the UK and the Commonwealth countries.

An odometer is a device used to measure the displacement of an object. It measures the distance travelled between the start point and the endpoint. Odometer is derived from two Greek words that mean path and measure.

#43. RPM Gauge/tachometer gauge.

A tachometer is an instrument that measures the working speed of an engine, typically in revolutions per minute (RPM). It is commonly used in cars, boats, planes, and other vehicles.

Most tachometer gauges have either an analog (dial) or digital (LCD or LED screen) display.

Digital tachometers are increasingly common on the market due to their reliability. They include fewer moving parts, which increases the life of the component.

Analog options are generally more prone to failure, which is further exacerbated by them having moving parts, as the location of a tachometer is usually close to the engine bay where vibrations are the strongest.

KUS manufactures analog and digital tachometer gauges for vehicle and marine applications.

Our KMG Touch/Button Gauge is a multifunctional instrument with tachometer functionality. We also manufacture an NMEA Tachometer Gauge compatible with NMEA 2000 systems.

A tachometer helps gauge how hard your vehicle’s engine is working, regardless of whether that vehicle is an automatic or manual transmission (road vehicle) or marine gear (boat).

Machinery typically has an optimal working speed; if it’s running too fast, it might suffer damage. If it’s running too slow, there might be a problem with the machine or its power source.

For example, poor lubrication, mechanical friction, or too great of a load might be slowing it down. A tachometer accurately indicates [working] speed.

For example, in an automatic transmission vehicle, a tachometer can tell you if the transmission shift points are in range or if the transmission is slipping.

In a manual transmission vehicle, you can use a tachometer to determine the optimal time to shift gears (but it is not required).

Meanwhile, in marine applications, a tachometer allows you to identify the best operating range for your engine while ensuring that you don’t exceed your maximum engine speed.

It also may secondarily inform decisions the vessel’s owner makes surrounding performance and fuel consumption.

#44. Cruise Control.

Cruise control is a feature that comes in handy when you drive at a constant speed. It is an electric system that allows you to set your car to a specific speed, letting you take your foot off the accelerator pedal.

So, it can ease foot-fatigue and stress over a long drive. Another great benefit to using cruise control is that you are going to have greater fuel efficiency.

Your vehicle will consume much less fuel if you cruise at a steady speed rather than accelerating at each section of the open road.

When you accelerate sharply, it makes your engine use more energy, and you could be using 60% more fuel than one who uses cruise control. Ultimately, it’s not hard to save on fuel if you let your vehicle automatically maintain a steady cruising speed.

The leading edge of cruise control today is adaptive cruise control. Almost all cars now will be equipped with this smart system. Just as conventional cruise control, adaptive cruise control allows you to set a desired travel speed.

But the difference is that the adaptive cruise control maintains a safe distance between the car in front of you and your car at a consistent pace by using the forward-mounted sensors.

For instance, if the car ahead of your vehicle begins to slow, adaptive cruise control will use the engine brake to automatically slow the pace of your vehicle and maintain the selected distance.

Many say adaptive cruise control is a step to autonomous cars in the future. But it is not quite fully autonomous driving, since you have to keep your hands on the wheel and be fully cognizant of the road.
