Interior Car Body Parts Names with Pictures

1. Engine

The engine is one of the most important interior components in an automobile, sometimes referred to as the “heart” of a vehicle.

The engine’s function is to transfer the heat produced by burning fuel into the power that moves a vehicle.

2. Transmission

The transmission, also known as the gearbox, is a crucial interior part of a vehicle. It is positioned in the engine, and it changes the burning power of the engine into driving energy that moves vehicles.

You can use the gear to adjust speed and strength based on the driving conditions you’re encountering. There are several gear ratios that drivers can select based on the vehicle’s speed.

3. Battery

Automobiles have batteries that can be recharged and used mainly to start a car.

The primary function of a battery is to supply electrical power to a vehicle, which then activates the chemically-fueled combustion engine that drives the car.

The battery is part of the starting system. Other uses include providing power for short-time use in lighting and audio when the engine is off.

4.  Alternator

An alternator generates electrical energy used to charge other vehicle components.

The alternator is located next to the engine, where it receives mechanical energy to generate electrical power.

Most cars that use an internal combustion engine (excluding a few hybrids) have alternators. The alternator is also used in charging automotive batteries and supplies power where needed.

5. Radiator

Radiators are designed to remove the heat generated by the engine.

As soon as the thermostats around the engine detect too much heat, the procedure of heat elimination starts right away.

The radiator releases coolant into the engine to reduce the heat. Excess heat is released from the vehicle.

6. Brakes

The automotive brake is situated on the left side of the gas pedal. Brake pedals usually have a broader, square form.

Brakes slow down or stop a moving car by absorbing or transferring movement energy, typically through friction.

7. Fuel Tank

A fuel tank is a crucial component of the fuel system. Various fuels, such as petrol, diesel, and natural gas, are stored in the fuel tank.

Fuel tanks have an inlet via which fuel can be pumped. They also include an opening that allows fuel to flow into the engine.

8. Muffler

The muffler is an interior component of the exhaust system located at the back of automobiles to minimize engine noise.

When burned gases exit the exhaust, the sound wave generated by the combusted gas is quite loud. The sound is reduced and released into the atmosphere using a muffler.

9. Axle

An axle is a rod located under the car that holds two wheels together so they can move and maintain their position.

An engine’s force drives the vehicle ahead by turning the wheels on the axle. The axles are responsible for transferring engine power to the wheels.

The axle should support the overall car weight, trunk load, and people in the vehicle while executing this critical operation.

It must also support acceleration power and braking forces.

10. Catalytic Converter

A catalytic converter oxidizes toxic exhaust gases to transform toxic pollutants into less harmful emissions.

Carbon monoxide and hydrocarbons are all present in a vehicle’s exhaust gas due to the engine operation.

These hazardous gases are converted to carbon dioxide and water vapour through a catalytic converter.

11. Dashboard

The dashboard is the central control panel in every automobile. It is usually found just toward the front of the drive.

The dashboard displays the car’s controlling instruments like the speed, steering wheel, gas usage level, storage compartment, audio or entertainment system, air vent etc.

12. Car Ignition System

The ignition system is responsible for igniting the mixture of air and fuel in engines.

The system achieves this by generating a very high voltage from the car battery, sent to all spark plugs that ignite the mixture in the combustion chambers.

The ignition system is made of several components, which include;

  • A spark plug is responsible for the ignition of air and fuel.
  • An ignition coil converts the voltage level of the battery to the high voltage required to ignite the spark plugs, which then ignite the fuel.
  • A distributor transfers the voltage output from the coils to the appropriate cylinder. The cap and rotor carry out the process.

13.  Steering Wheel

A steering wheel, also known as a driving wheel, is part of the steering system positioned at the dashboard. A driver rotates the wheel to control the movements of a vehicle.

14.  Seat and Seat Belt

All cars have a driver and passenger seats, both of which are fitted with seat belts.

A seat belt, also known as the safety belt, keeps you safe in your car in case of a crash or an unexpected stop.

15.  Parking Brake

The parking brake sometimes called a handbrake or an emergency brake, is a tool that keeps the car safely static when parked.

The handbrake can also be used for instant braking in an emergency.

16. Clutch and Gas Pedal

Only vehicles with manual transmissions have a clutch pedal.

The clutch is positioned on the far left side. Pressing the lever causes the discs to separate from each other, allowing the transmission to detach from the engine so you can quickly change the gear.

The gas pedal, also called the accelerator pedal, is positioned at the far right on the car’s floor at the driver’s side.

It regulates the speed of your car by controlling the quantity of fuel put into the engine.

1)  Hood

The hood is the component that provides access to the engine. It is positioned at the front of the car, where the engine is installed.

Apart from covering the engine and its elements from every foreign material, the hood serves to keep things secure. It may be opened to provide you access to the engine and other components.


The windshield is the large front glass that provides a clear vision of the road for the driver. The primary function of the windshield is to protect the driver from wind and any particles or dust.


Bumpers safeguard drivers and the car from major harm in low-speed crashes by absorbing the majority of the force.

Bumpers are generally acceptable safety equipment because of their role in shielding drivers and passengers during minor accidents.


Wheels are spherical formations that create rotating motion and move the automobile from one location to the other.

Wheels work together with the rubber tires and rims to move vehicles from one point to another.

Steel, aluminum, and chrome are the three most common materials used to make rims. You may also find wheels or rims made from magnesium alloy.

Steel rims are somewhat out of date. Steel used to be the most common material for conventional wheels, but auto companies are shifting to lightweight metals to improve fuel efficiency.

5. Trunk

The trunk is the space or cargo area, usually found at the back of a vehicle.

The trunk is mainly used to transport stuff and sometimes house spare tires and repair tools.
