Information on Car Parts and Their Purpose.

Information on Car Parts and Their Purpose.

It is generally seen that people are in love with their vehicle. They take care of their cars as a living being to understand their language and keep them in good and maintained condition. Being responsible is required if you are a car owner to keep your car new and smooth when operated. It does not need rocket science to take care of it. However, a car is a component of almost 30,000 unique parts. Therefore, you need to know at least some essential features only. To understand the mechanism of a car, understand their function, and understand the importance of the parts of the car. 

Here, we provide you with a list of some crucial parts of a car with their uses to know every driver. 


Yes, of course, you know about it. But who should add the chunks of the knowledge about the working of it? The engine comprises a camshaft, crankshaft, spark plugs, cylinder heads, valves, and pistons. In the cars, there are internal combustion engines. Fuel enters the vehicle where it is combusted in the pressure of air to produce an air-fuel mixture that helps to move the car. Thus, the machine is sometimes called the heart or the soul of the vehicle. 


The radiator is located near the engine because the preparatory work of the radiator is to prevent the engine from getting overheat. The working of the machine makes it hot, and to prevent it. Coolant runs throughout the vehicle. It needs to have a sufficient quantity of coolant for its smooth working continuously. Twice a year, who should check the coolant level. 


Your engine may be in perfect condition, but your car won’t run without a battery. The battery delivers the electricity needed to run your car’s electronics component. It is a critical component that even allows your vehicle to start in the first place. It is usually located under the hood and can be recognized by + and – symbols. Some components of the battery are as follows.

● Battery Terminal

 A medium to connect the battery with the electronic component of the car. There are + and – terminals. 

● Battery Capacity

Amp/hours is the standard by which the energy output of the battery is measured. 

● CCA 

Stands For ‘Cold Cranking Amps’ the amount of current the battery supplies to the automobiles. 


The alternator is a power generating device. It is used to supply power to your car’s electrical system. How is it done? It charges the car’s battery with mechanical energy, and that mechanical energy is generated when the vehicle moves. The alternator is the device to convert the mechanical energy of the battery into electrical energy in the form of alternating current. 

Shock Absorber or Suspensions.

They are a crucial part of the car to help in improving the ride and maintaining stability when you drive your vehicle on an uneven road. 

There are three essential functions of a shock absorber. 

● Mitigate the effects of spring oscillation to control the stabilization of drive. 

● Control up and down, rolling motion of car body and body sway. 

● Reduce the tendency of tire tread off. 

It fosters the friction between the road and the tire to stabilize the car and prevent any jerk from being felt by the driver. 


The transmission is a gearbox that contains gears and gear trains, and it makes effective use of the engine’s torque or rotational power, in layman’s terms, pull power. Transmission can be located differently depending on which wheel drive your car is. Front-Wheel Drive ( FWD) or Rear Wheel Drive (RWD). 

● Front-Wheel Drive

The front-wheel-drive features the engine under the hood. The transmission will be located between the transaxles and behind the machine. 

● Rear-Wheel Drive 

With rear-wheel drive, the transmission is bolted to the engine. The engine is found at the back or in the middle of the rear part of the car.

There are two types of transmissions.

● Automatic Transmission. 

Using ATF automatic transmission fluid, the gears are changed automatically. The engine computer controls the shifts. As a result, some transmission is shiftless, sometimes known as CVT continuous variable transmissions. 

● Manual Transmission

This is a manually shifted gearing device. It allows the variation of the relationship between engine speed and road speed. 

Catalytic Converter 

It can be understood as an eco-friendly component of the car. It is a part of the emission system and works as a converter of harmful gases into less toxic gases. It is made of stainless steel and contains a catalyst that reduces the Oxides of Nitrogen (NOX), Hydrocarbon (HC), and Carbon Monoxide (CO) in tailpipe emission. This is an essential part from an environmentalist point of view. 

Exhaust System

The exhaust system is responsible for moving the burnt air-fuel mixture out of the engine. It also works as a cleanser as it cleans the emission and also lessens the unnecessary sound. This also affects the overall performance of your car. 

There are many parts of the exhaust system. 

● Exhaust Manifold 

It collects the different emitted gases and kites them into one single pipe. 

● Oxygen Sensors

There are two sensors. As the name suggests, they work to sense the level of oxygen in the exhausted air. 

● Pipings

These serve as a connection between different parts of the exhaust system.

● Muffler or Silencer

Yes, you are right. It is used to reduce the sound. 

● Tailpipe

At the end of the exhaust system, a part is called the tailpipe, which finally exhausts the gases out of the car. 

Ignition System 

The ignition system is made up of spark plugs, ignition wire, coil, and distributors. Primarily it brings out the fuel combustion, which occurs in the presence of the air. Then, it generates the spark or heats an electrode to ignite the fuel-air mixture in spark-ignition internal combustion engines. 


Axels are like the axis of the earth. The wheels move or rotate around them. They are an essential part as the wheels are attached to them. There are two axles, ‘The Front Axel’ and ‘The Rear Axle.’ They are cross members supporting a vehicle where the wheel hubs are attached. They are also part of the gear system and the suspension system. Send power to the wheels from the engine through transmission and differential. They link the vehicle to the wheels and support the weight of each. The human body has cells that make tissues, tissues create organs, and organs make an organ system. So, as is the case with cars or automobiles, there are many other small parts, and the features make a whole system, like, ignition system, exhaust system, transmission system and that makes a real car. Knowing about the details is not enough. You need to take care of those and be a responsible driver or owner. Understanding the parts makes you more conscious of the needs of your car. You know it more nicely. Now, you differentiate the sounds of peril and easily can make it right. I hope this would prove a better help for you, and we could have added something extra to your already possessed knowledge.
