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.
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.
the function of an exhaust manifold on a gasoline or diesel engine is to expel the burnt fuel from the combustion chamber of each piston out through the exhaust pipe after each combustion stroke of the piston has been completed.
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
A gas engine ignites gasoline in the piston chamber with a spark from a spark plug. The expanding gas then pushes the piston out and the motor moves forward. A diesel engine uses diesel fuel, different from gasoline, and the fuel is compressed by the piston until it ignites, sending the piston out. There are no spark plugs in a a diesel engine. Some diesel engines will have "glow plugs" which are used to initially start the engine but once started, compressing the fuel is the method of ignition.

Currently, diesel engine pistons are typically made of steel - aluminum was used previously, as it had better heat sink properties, but metallurgy has improved steel enough to the point where it holds up fine now. The highest ring on current production diesel engines is at the top of the piston now - this was in response to emissions requirement. Gas engine pistons are flat at the top, as it is a spark which ignites the fuel/air mixture; diesel engine pistons often have the 'Mexican hat' at the top of the piston, as they ignite through compression.
Worn piston rings.
Because of Ring burnt, engine heat-up or loose piston in sleave.
It means that it is a six cylinder naturally-aspirated diesel engine with 125 mm piston bore
It connects the piston to whatever the design calls for the piston to push or pull on. In a combustion engine, the piston rod connects the piston to the crankshaft, turning linear reciprocating motion into rotary motion.
Its a compression engine, as opposed to a spark driven combustion. No spark plugs! To start the engine, the piston is forced up (by a starter), it compresses the (heated) fuel in the piston which then ignites (under pressure) forcing the piston back down and initiating the engine to turn over.
