parts of a car

To understand how a car works, it is important to know the different parts that make it up. Here are the most important parts of a car:

1. Chassis

The chassis is the main structure of the car, providing support and rigidity. It is like the skeleton of the car, on which all the other parts are mounted.

2. Bodywork

The body is the external part of the car, which gives it its shape and appearance. In addition to being aesthetically pleasing, it also protects the vehicle's occupants.

3. Motorcycle

The engine is the heart of the car, responsible for generating the energy necessary for the car to move. It is made up of different parts, such as the engine block, cylinders, valves, and fuel system.

4. Transmission

The transmission is the system responsible for transferring the power generated by the engine to the wheels of the car. It can be manual or automatic, and consists of different components, such as the clutch, gearbox and differential.

5. Suspension

The suspension is the set of elements that absorb the irregularities of the terrain and provide a smooth and comfortable ride. It is made up of shock absorbers, springs and stabilizer bars.

6. Brake system

The braking system is essential for the safety of the car. It allows the vehicle to be stopped in a controlled manner and consists of different components, such as discs, pads, calipers and brake fluid.

7. Steering system

The steering system allows the driver to control the direction of the car. It is made up of the steering column, the steering box and the front wheels.

8. Tires

Tires are the only points of contact between the car and the road. They are responsible for providing traction, grip and stability to the vehicle.

running a car

Now that we know the main parts of a car, it's time to understand how it works. The operation of a car is based on the principle of internal combustion, where the engine converts the chemical energy of the fuel into mechanical energy. Below, we briefly explain the process:

1. Admission

The process begins with the intake of air and fuel into the engine cylinders. The mixture is compressed and ignited by a spark generated by the spark plugs.

2. Explosion

The spark causes a controlled explosion inside the cylinders, which pushes the pistons down. This mechanical energy is transmitted through the crankshaft and converted into rotary motion.


After the explosion, exhaust gases are expelled from the engine through the exhaust system. These gases are treated by the catalytic converter before being released into the environment.

Driving vocabulary

When driving a car, it is important to know the vocabulary used in the field of driving. Here are some common words and phrases:

1. Accelerate

Increase vehicle speed by pressing the accelerator pedal.

2. Brake

Slow down or stop the vehicle by using the brake pedal.

3. Gear change

The action of changing the gear ratio of the vehicle to adapt to different speeds and driving conditions.

4. steering wheel

Device used to control the direction of the vehicle.

Frequently Asked Questions

1. What are the basic parts of a car?

The basic parts of a car include the chassis, body, engine, transmission, suspension, brake system, steering system and tires.

2. How can I identify the main parts of the engine?

To identify the main parts of the engine, you can consult your vehicle's owner's manual or search for information online. You can also go to a mechanic or auto expert to help you identify the different parts.


In short, knowing the parts of a car and how it works is essential for anyone interested in the world of vehicles.
