The piston in a petrol engine moves up and down within a cylinder, converting the pressure generated by burning fuel into mechanical energy. As the piston moves, it transfers this energy to the crankshaft, which in turn drives the vehicle's wheels.

What is function of a piston in a diesel engine?

The piston has the same function whether diesel or petrol. The piston is forced down the cylinder when the petrol mixture ignites and expands. That in turn presses on the connecting rod which in turn pushes on the crankshaft. The crankshaft changes the up and down movement of the piston into a rotational movement which makes the car go.


Why petrol engine is called as spark ignition engine?

A petrol engine is called a spark ignition engine because it uses a spark plug to ignite the air-fuel mixture in the combustion chamber. When the engine's piston compresses the mixture, the spark plug generates a spark that ignites it, causing an explosion that drives the piston down. This ignition method distinguishes it from diesel engines, which rely on compression ignition. The term reflects the fundamental mechanism by which combustion occurs in petrol engines.
