What's the Difference Between 2-Stroke and 4-Stroke Engines? 

You probably have some knowledge of how internal combustion engines work. They involve pistons, Cams, explosions, etc. but do you know what the differences between 2-stroke and 4-stroke engines are?
The history of automotive and engine design has been marked by the existence of two main types of gasoline powered combustion engines: the 2-cycle and 4-cycle engine.
The name of each of these engine types suggests exactly how they operate. In order for any engine to complete combustion and thus drive their respective vehicles or machines, there needs to be combustion of the gas-air mixture and expulsion through the exhaust ports. The main differences in these two engine types is just how they approach this process.
