Six Stroke Engine

It is an era of high speed and high performance engines. Six stroke engine is also a type of internal combustion engine which additionally adding two strokes to the four stroke engine. In the fifth stroke the water is injected into the cylinder and the sixth stroke is exhaust stroke. Generally four stroke engine having only one power stroke and the six stroke engine having two power strokes. It may increase the efficiency of the engine and reduce the fuel consumption. The specific power of the six stroke engine will not be less than the four stroke engine. It may increase in thermal efficiency of the engine due to two additional strokes. By adding this additional strokes we may reduce the noise and thermal pollution. The additional stroke cools the engine by water and removes the need of a cooling system and gives 40 % increased efficiency over the normal Otto cycle. The components used in the six stroke engine is quite similar to the four stroke engine with additionally adding of two valves. The research on Six stroke engine has excited our interest to locate its weak points.
