Engine parts:


Pistons are cylindrical components that move up and down inside the engine cylinders, forming the engine’s power strokes.


The crankshaft is the main component that converts the up-and-down motion of the pistons into a rotary motion used to drive the wheels.


The camshaft is responsible for opening and closing the engine’s valves in time with the pistons.

Engine block:

The engine block is the main component of the engine that contains the cylinders, crankshaft, and camshaft.

Transmission parts:

Transmission fluid is the lubricant used to keep the transmission components moving smoothly.

The gearbox is the component that houses the gears and allows the driver to change the speed of the car.

Braking system parts:

Brake pads:

Brake pads are the components that press against the brake rotor, providing the friction that slows the wheels.

Brake rotors:

Brake rotors are circular discs that the brake pads press against to slow the wheels.

Brake calipers:

Brake calipers are the components that hold the brake pads in place and apply pressure to the brake rotors.

Suspension system parts:

Shock absorbers:

Shock absorbers are the components that dampen the vibrations and bumps the wheels encounter while driving.
