How does the engine work?

The engine is the heart of a vehicle, and it works by converting fuel into energy that can be used to power the vehicle's movement. In most modern vehicles, the engine is typically an internal combustion engine that burns fuel and air to produce energy in the form of rotational motion.

The process of how an engine works can be broken down into a few basic steps:

Intake: The engine takes in air and fuel, which are mixed together and delivered to the combustion chamber. 

Compression: The piston compresses the air and fuel mixture, which increases its temperature and pressure.

Combustion: The spark plug ignites the compressed air and fuel mixture, causing it to burn rapidly and release energy in the form of expanding gases.

Exhaust: The piston moves back down, expelling the burned gases through the exhaust valve.

This process is repeated in a continuous cycle, with the engine producing power as a result of the combustion of fuel and air. The engine's power is transmitted to the wheels of the vehicle via a transmission and drivetrain system, allowing the vehicle to move.
