Answer The piston is a key engine part, which is used to compress gases withing the combustion chamber or cylinder of an engine. The piston is sealed with a piston ring, often constructed under freezing temperatures, to allow expansion and therefore complete sealing, to seal the chamber to prevent leaks, or dangerous gases escaping. As the piston moves downwards, a valve opens to allow fuel into the chamber, this fuel is then compressed, combusted and expelled. All of which is transferred through the cam or prop shaft, through a differential and gear box, into the axle and ultimately onto the road via the tire.

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.
The piston includes the piston, rings, rod, rod bearing, and crankshaft bearing.
WHAT ARE THE BASIC PARTS OF PETROL ENGINE? HOW DOES PETROL ENGINE WORKS?
piston is a plunger that moves ups and down in the engine block.the function of the piston is to compress air mixtures in the engine block
Many use standard petrol, some use high octane petrol.
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.
by compression test
Misfiring on a petrol injection engine is caused due to incorrect ignition timing. As the engine rotates, the timing determines when each piston fires or ignites.
The crankshaft converts the linear motion of the piston into rotation of the crankshaft.
The volume occupied by the cylinder when the piston is at top dead centre is called clearence valume.
engine block, it's function is to carry the engine or where the cylinder head set, piston, it;s function is to compressed the air and fuel.
In diesel engine ,air alone without any fuel is drawn by the falling piston during inlet stroke. In petrol engine, the mixture of air and fuel is drawn in by the falling piston during inlet stroke. There is no difference in the act of actually setting the timing. Inlet valves open slightly before the piston reaches top dead centre, by how much depends on the manufacturers specifications.
