The four-stroke engine used in automobiles is an example of an internal combustion engine.
In Diesel Engines the compression is used to ignite the fuel at the end of the compression stroke. And there is no spark plug to start ignition. As the air is compressed during the compression stroke, according to guy lussac's law the temperature is increased which completes the combustion triangle.from : Umer Azhar (Chemical engineer from UOG)

Dome Pistons are used in 2 stroke engines.
The difference is in the size of the engine. Specifically in the intake and exhaust ports. The bore and stroke of the crank and pistons and the size of the combustion chambers.

A four stroke internal combustion engine can have any number of pistons, from one to one million. They usually have even numbers in order to maintain engine stability. The "four stroke internal combustion" signifies the type of engine. There are two stroke internal combustion engines, mostly one or two cylinder engines used in lawn mowers. An internal combustion engine is one that ignites an air fuel mixture within itself and uses the resulting explosion for power. There are external combustion engines, which are usually powered by steam heated in a separate container and pumped into the engine. Four stoke engine utilize a four step (or stroke) process in order to run. The steps are the intake stroke, where the engine breaths in air and fuel, the compression stroke, where it squeezes the air and fuel, the power stroke, where it ignites the air fuel mixture, and finally the exhaust stroke, where it pushes the remains of the ignition out. See the attached link for a graphic description of how two and four stoke engines work.
Compression and ignition
A stroke in an internal combustion engine is when a piston moves up or down.
The four-stroke engine used in automobiles is an example of an internal combustion engine.
The flywheel in an engine stores the energy given to it by the moving pistons and smooths the rotation. In single cylinder engines the power stroke of the piston would cease immediately if it were not for the flywheel continuing the exhaust stroke to rid the cylinder of the spent gases.
The compression stroke is not part of the engine. It is what happens when the pistons are on the upward with closed valves.See link below.The compression stroke is not part of the engine. It is what happens when the pistons are on the upward with closed valves.See link below.
The combustion stroke is where all of the power from an engine is derived making it the most important however the other strokes play a role in how well the combustion process is completed. Each stroke is vital in the process of combustion.
