Can anyone tell me about the parts of two stroke engines and four stroke engines separately?

Question by Sky’s The Limit: Can anyone tell me about the parts of two stroke engines and four stroke engines separately?
tell me the names of the parts of two stroke engines and four stroke engines separately.
and if possible, please explain in one or two line about the functions of those engine components.
you can copy and paste from anywhere, or you can write. please help, because I couldn’t find anything about it. thank you.
@Jackal Hyde: Sir, thank you for your answer. but I was asking about engine components, the parts.
I already know about Otto and Diesel Cycle. 🙂

Answer by Jackal Hyde
With a four stroke, you have four separate strokes for each of the following.

– Intake.
This is where the piston travels down the cylinder whilst the intake valve opens to let the mixture of fuel and air enter the chamber.
– Compression.
The intake valve closes while the piston travels back up, this in turn, compresses the gases.
– Combustion.
The spark plug ignites the compressed gases. This then sends the piston back down.
– Exhaust.
The piston rises back up, the exhaust valve opens and the piston then clears the chamber new again.

As for two stroke, it’s all of the above, but integrated into an upward and downward stroke. Both intake and exhaust are integrated with the compression and combustion of the piston. From this, there is no need for valves.

Hope this helped, I know it wasn’t much..

    Surprisingly, both 2 and 4 cycle engines use virtually the same nomenclature for their individual parts.

    They both have crankshafts, pistons, connecting rods and valves, as well as exhaust and intake systems, and fuel delivery. The differences will lie in the “valve arrangement.”

    While both may utilize both intake and exhaust valves, they are not similar in appearance. Some 2 strokes use reed type valves that open and close with each piston stroke. Others use “ports” that do the job of the valves.

    You really need to understand the operating principles before you can answer your question.
