Four and two stroke engines

Four and two stroke engines.

Two-stroke engines do not have valves and other mechanical parts distribution, due to their simpler design and less weight;
 Two-stroke engine is much more powerful than the same displacement four-stroke engine; Two-stroke engines can operate in any tilt position while inverting the standard four-stroke engine in its crankcase oil may begin to seep in and interrupting engine lubrication system.

Four-stroke engines generate significantly more torque, especially in the low speed range, consume significantly less fuel, as well as slower wear for better lubrication. Of course, four-stroke engine sound much richer and lower. Four-stroke engine has a lot of rotating and other moving parts, it's more complicated to maintain and repair these engines are more expensive.
