Parts of a Car & their Functions


The engine is a power source that produces the power to run the car on the road. It uses air and fuel to generate power by combustion in the combustion chamber.

It consists of the 3 main parts; a heavy engine block, a casing that encloses all moving parts, and a detachable cylinder head.

In a gasoline engine, when the piston compresses the air and fuel mixture inside the combustion chamber, an explosion occurs, and the piston moves downward. This reciprocating motion repeatedly happens in the engine.

The reciprocating motion of the piston transmits through connecting the rod to the crankshaft and converts it into the rotary motion. Hence the car wheel rotates to run the car on the road.

Cam and follower system and electrical system play a prime role in opening and closing the inlet and outlet port of the engine at the accurate time through the valves to happen the combustion of fuel.

Inlet ports allow the air-fuel mixture to come into the combustion chamber, whereas the outlet port lets the exhaust gases drain out from the combustion chamber. The right timing of these valves decides the efficiency of the engine and its performance.

In between the engine and wheel, there is a transmission system present. It helps to change the car speed as per the requirement.

Also, the lubrication of each car engine part helps to increase the performance of the engine and its life.
Old automobiles have a rotary engine, or a Wankel engine, which has a circular construction. The function is the same, but their design is different.

The chassis is the main support structure of all vehicles, which bears all load and stresses in static and dynamic conditions.

The functions of the chassis are to take the load of the car parts and give them mounting locations. The chassis helps to withstand the passenger load and stress due to bad road conditions, braking & acceleration of the car.

Automobile chassis is made of several high-strength materials welded and riveted together to give the final shape. It provides locations to mount all primary parts of a car, and rubber packing helps to avoid the formation of the engine or mechanical vibration.

The rubber packings help to dampen and absorb vibration and give a comfortable ride to the passenger.

Car Body

The car body is a structure of metal sheets, which provides accommodation to the passengers and protects them from sun, wind, dust particles, and more items.

The multiple sheets are drowned and punched at desired shape and size to form the car body. These sheets are welded and riveted on the chassis to give the desired shape.

In the market, multiple types of vehicles are available, which has different body shape. It also depends on the type of vehicle, manufacturer, and cost.

In modern cars, these sheets are too strong and protect the passengers during accidents. Aluminum and its alloys are the best choices for car body parts due to their high strength and low weight.

Air Conditioning System

The function of the air conditioning system is to absorb the heat from the car inside and supply cool air. It is done by the refrigerant manipulation from a gas to a liquid or vice versa condition during the whole refrigeration process.

The primary part of the air conditioning system is a compressor, evaporator, condenser, expansion valve, and refrigerant.

The compressor compresses the vapor refrigerant that comes from the evaporator. It increases the temperature and pressure of the refrigerant.

From the compressor, the refrigerant passes to the condenser coil, where it ejects the heat and turns it into liquid form. But, the refrigerant has a high temperature when refrigerant passes through the expansion valve, its pressure and temperature decrease.

When this refrigerant passes through the evaporator, it begins soaking heat from the surroundings and produces the surrounding atmosphere chilly. Due to that, refrigerant starts boiling and turns into vapor.

So the same process repeats to get a chilly atmosphere inside the car cabin.

Lighting System

The lighting and signaling devices are on the front and rear sides of the vehicle. Its function is to recognize the road, signs, and obstacles and illuminate the lane.

Headlights come with high rays and low beams primarily for recognition purposes. The signaling lights indicate the direction of the turn, whereas the rear red lights indicate the danger or stop indication for other vehicles.

Car interior lighting increases the look of the car. It exists in the speedometer, fuel indicator, dashboard, music player, primary interior light, below the seat, and more.

Engine Cooling System

When fuel combustion happens in the combustion chamber, a lot of heat develops. This heat directly affects the engine parts hence the temperature of these parts increases.

It causes a decreasing the life of the component and engine efficiency. If we have a proper cooling system for the engine, then we can cool down the temperature of engine parts to increase the performance and efficiency of the engine.

A cooling system in a car prevents the engine from overheating and overcooling. In both conditions, there are chances of decreasing engine efficiency.

Lubrication System

In the automobile engine, multiple moving parts experience lots of friction. Due to that, there are chances of wear out of these parts and failure.

To avoid it, a lubrication system is necessary for the car engines. The lubrication system supplies the oil to those parts and helps to reduce the friction between them.

Also, oil gives smooth movement to these parts. Eventually, it helps to increase efficiency and reduce power loss and the life of the engine parts.

Furthermore, oil acts as a sealing medium in the reciprocating motion of the piston in the cylinder. Lubrication film on the engine cylinder wall helps the piston ring in sealing. Due to that, leakage reduces, and compression of fuel occurs efficiently.

Ignition System

The function of the ignition system is to ignite the spark in the combustion chamber at the right time for the complete burning of the fuel. Complete burning of the fuel increases the machine’s performance and efficiency.

In the IC engine, the spark plug is responsible for the fuel ignition at power stroke. But in the CI engine, the spark plug is not present.

Air is compressed in the cylinder at power stroke, which increases the temperature of the air. At the right time, the fuel is injected through the fuel injector for the complete combustion of the fuel.

Electrical System

As we all know, many electrical and electronic components are present inside the car. The magneto, alternator, voltage regulator, and battery are the major components of the electrical system.

These components help to operate the ignition system, lighting, windshield cleaning mechanism, air conditioning system, and many others.

The breakdown of any electrical component can disturb the whole electrical and electronic equipment, which affects the car’s performance.

Transmission System

The function of the transmission system is to transfer the power from the engine to the car wheel. With the transmission system, we can vary the torque applied by the engine to the car wheel. It is done by altering the engine output and drive shaft gear ratio.

The transmission system is mounted on the front portion of the chassis and in line with the engine. There are different types of transmission systems available manual, semi-automatic and automatic.

As per the requirement, we can change the torque and speed of the car through the transmission system. It helps to increase fuel efficiency and gives good comfort.

Steering System

The function of the steering system is to turn the car in the desired direction. It is generally at the front wheels of the car.

The steering mechanism converts the rotation of the steering wheel into a swiveling movement of the car wheels in such a way that the steering-wheel rim turns a long way to move the car wheels a short path.

Hence the driver requires less force to turn the car. It guides your car in all road conditions and helps you to be on the right path.

There are different steering mechanisms available in cars. But modern cars use power steering due to their smooth and efficient steering mechanism.

Suspension System

The function of the suspension system is to absorb the shocks and vibrations due to the up and down motion of the car wheel when a car runs on an irregular road surface. It helps to give a comfortable ride to the passengers.

The suspension system has a linkage, upright, and springs assembled. It is available on four wheels of any automobile.

There are 3 types of suspension systems.

  • Dependent
  • Independent
  • Semi-Independent


It uses stiff linkages that connect two wheels of the same axle. When one wheel passes through the irregular surface, the other wheel spring is also affected, as both have the same axle. It helps to divide the shocks and vibrations.

A leaf spring is a suitable example of a dependent suspension system.


In an independent suspension system, each wheel has the freedom to move and has individual suspensions. When one wheel passes through the irregular surface, only the suspension system experiences shocks and vibrations.

Coil spring suspension is the best example of an independent suspension system. In a modern car, pushrod suspension system technology is more advanced. It gives much comfort to the passengers.


It is a combination of dependent and independent suspension systems. The suspension of both wheels is independent, but one wheel’s position impacts the other wheel’s position.

The Twist beam is the best example of a semi-independent system.

Fuel Supply System

It is for supplying fuel at the correct timing into the engine. Its function is the same, but the mediums are different to deliver the fuel into the engine.

The petrol engine uses the carburetor to mix the petrol into the air and supply it to the engine as per requirement. The engine has an inlet port that opens and closes at the correct time to deliver the air-fuel mixture.

In the diesel engine, the fuel injector directly injects the fuel into the combustion chamber during the power stroke. Like a petrol engine, inlet ports drive the air into the combustion chamber and close as per their valve timing.

Brakes System

The function of the braking system is to slow down the automobile’s speed. When the vehicle is in motion, it is necessary to control its speed otherwise, there is a chance of an accident. So the speed is controlled by applying a brake.

There is a mechanical and hydraulic braking system available in the vehicles. The old automobile has a mechanical braking system, whereas the new car has a hydraulic braking system. The hydraulic braking system is more efficient than the mechanical braking system.

This system consists of one rotating and another stationary member. The static member applies pressure on the rotating member to reduce the vehicle speed by the principle of frictional resistance.

When we apply the brake, the force acts on the axle and wheel, and friction occurs between the tire and the road. It creates shocks and vibrations, which are absorbed by the shock absorbers and help to maintain contact with the wheel tire with the road.

The braking system parts are the brake pedal, wheel cylinder, brake drum, hydraulic master cylinder, brake packing plant, brake shoes, and linkages.

Clutch System

Its function is to detach the engine drive from the vehicle’s wheel drive. It helps to change the gear ratio to maintain the desired torque and speed of the automobile.

The Clutch system consists of a pressure plate and a friction plate. When our vehicle is in motion, friction and pressure plates are engaged with each other.

During changing the speed or torque, we apply the clutch, which causes us to separate the pressure plate from the friction plate. It disconnects the engine from the wheel drive, and we get time to change the gear ratio.

There are single-plate, multiple, and centrifugal clutch systems available. In the automatic transmission system vehicle, a centrifugal clutch system is used.

Signaling System

The signaling system consists mainly of sensors. It gives signals to various devices to operate. It also notifies us through mobile or calls.

  • In accidental conditions, the sensor gives a signal to open the airbags.
  • We indicate the vehicle through the keys to lock and unlock the car.
  • If we forget the car, we get a message about its location.
  • It sends the notices to our close once in the accidental conditions.
  • Tracks our live location and directs us the proper way through GPS.

Exhaust System

The function of the exhaust system is to drain out the exhaust gases from the engine cylinder for the next suction stroke. Parts of the exhaust system are the exhaust manifold, catalytic converter, oxygen sensor, exhaust pipe, silencer, resonator, tailpipe, and gasket.

To drain these gases, exhaust ports open and close through exhaust valves. Next, these gases pass from each cylinder to the exhaust manifold and combine at the end of the manifold. Further, it went to the silencer through the catalytic converter.

The catalytic converter converts harmful gases into harmless gases, and the silencer and resonator reduce the noise coming from the car. Each of these parts is connected through the pipes.

Seating System

It gives a comfortable seating position to the driver and passengers. With time there are so many advancements happening in the seat design.

Nowadays, recent cars have provision to adjust the seat as per our requirement. We can fold them, move up-down, front and back, change the angle of inclination, and remove them from the car.

These are designed by taking various previous data into account and new technology. Due to that, drivers don’t face any physical issues while driving. It helps to drive a car very comfortably and reduces the chances of accidents.


The battery is the power source for the electrical and electronic parts of the car. To start the car, we need to trigger the starter motor, which is the main operation done by the battery. It also helps to operate spark plugs, fuel injection systems, and various sensors.

SLI batteries are the most common type of battery for automobiles. It delivers more current for starting ignition, lighting & ignition. These are commonly lead-acid batteries.

Commonly all automobile batteries deliver power at 12v to 24v, and the power rating of all electrical and electronics are suitable for these two voltages only.


It is a generator for automobiles. It is at the front portion of the car, near the engine, and connects with the crankshaft through the serpentine belt. The main parts of the alternator are the rotor, stator, regulator, rectifier, and pulley.

When a car is going on the road, it charges the battery and supplies the power to all electrical and electronic parts of the car.

When the engine starts, the alternator starts rotating through the serpentine belt. Pulley has a groove to fit the serpentine belt and is connected to the rotor.

When the rotor rotates inside the stator winding, it induces the electric current or EMF in the stator copper coils. Furthermore, the regulator regulates the constant voltage, and the rectifier converts the AC to DC during the charging process.

Radiators are heat exchangers which help to cool the engine. Not only in the car engine, but the radiator is also present in all sorts of engines to cool down the engine temperature.

In the automobile, coolant is circulated close to the engine through pipes to cool down its temperature. When the coolant passes through the surfaces of the engine, it cools the engine and becomes hot.

Once it comes into the radiator, it starts losing its heat and getting cool due to obtaining contact with the air. Fins of the radiator and pipe surfaces help to cool the coolant faster. A similar process repeats multiple times to cool the engine.

Automobile engines are either water-cooled or oil-cooled. Depending on the type and manufacturer, it varies.


Sensors are electronic sensing devices that sense different aspects of the vehicle and send signals to the driver or ECU. As per the program in the ECU, it automatically controls the component moment.

It senses the engine temperature, coolant, oil pressure, vehicle speed, valve timing, O2 level in exhaust gases, and other data.

Drive Shaft

The driveshaft is the propeller shaft of the vehicle. It connects the gearbox to the differential and has a universal joint at the end to adjust the inclination.

It transfers the rotary motion and torque from the engine to the vehicle wheel. When a vehicle passes on uneven roads, the up and down movement of the rear axle and differential assembly causes the load on the driveshaft. To solve this problem, the drive shaft has the inclination and adjuster to adjust the length.

Designing and material selection of the propeller shaft is very important as it is subject to very high stresses and torsional forces. 

The drive shaft parts are the U joint, tube, center bearing, midship shaft, end yoke, ship and tube yoke, and flanges.


The differential is the gear system that allows the two wheels on the same drive shaft to rotate at different speeds. It transmits the rotary motion that comes from the engine through the propeller shaft to the vehicle wheel.

Differential changes in the direction of the rotation like propeller motion perpendicular to the differential orientation through the gear arrangements.

It is available in most rear-wheel-drive vehicles. Its maintenance cost is less.


The axle is the shaft that helps to rotate the car wheels and support the automobile weight. The axle has a mounting point on which the bearing or bushing mounts to revolve the wheel. This bearing or bushing is the central part of the wheel.

The rear axle, front axle, and stub axle are the type of axles. The rear axle transfers the rotating motion from the engine to the wheel. The front axle helps to assist the steering mechanism. The stub axle connects the car’s front wheel, and the kingpin connects it with the front axle.


The wheel is only one rotating member, which causes the vehicle to get in contact with the road to run the car. The parts of a car wheel are the rim, tire, spokes, valve, stem, beads, center bore, and hub.

Fuel Tank

It is available in the middle or on the rear bottom side of the vehicle. It is easy to access because it is necessary to remove the fuel pump for maintenance.

The fuel tank has a leakproof opening to avoid contact with fuel and the atmosphere. In the car, this opening is protected by the rectangular flap or metal plate, which needs to open first while filling the fuel.

Fuel Gauge

A fuel gauge is a fuel level sensing device that displays how much fuel is current inside the fuel tank. It has an indicator outside the tank and a sensing mechanism inside.

When the sensing mechanism senses the fuel, it automatically sends the signal about the fuel level to the indicator, and we get the data on the screen.

Temperature Gauge

Its function is to measure the temperature of the engine coolant. We have an indicator on the dashboard to indicate the coolant state, which is cold, regular, or overheated.

When the engine starts running, coolant flows to cool down the engine. But if the temperature gauge gives the data of overheating of the coolant, then it might be a sign of some technical problem or any equipment damage.

CarTtrip Meter

It shows the distance traveled by car during the trip. We can set this trip meter before starting the travel. So we can easily find the distance we traveled.

Pushing the button on the car trip meter, we can find the current travel distance, and forcing one more time gives you the present overall travel distance.

In old cars, it was a mechanical trip meter available. But in the modern car, it is digital. It helps to calculate the mileage of the car. It gives you accurate data on the efficiency of the car.


The car hood is the metallic sheet that covers the front top portion of the car. It is also known as a bonnet in some countries.

It helps to protect the engine, air conditioning unit, radiator, battery, alternator, and more from dust, sun rays, wind, stones, rain, and more. Its design varies as per the car type and manufacturer.

With the concealed latch, we can open and hold the hood. Aluminum and its alloys are the first choice of material for hoods.
