What is 2 Stroke Compression Ignition Cycle

 

 

The 2 stroke compression ignition cycle (2 stroke diesel) engines are in use mostly in the marine industry. A 2 stroke compression ignition cycle or 2 stroke diesel engine differs from a 4 stroke diesel engine by the way it generates power in number of revolutions of the crankshaft. Unlike in a 4 stroke diesel engine, the 2 stroke compression ignition cycle produces power in its each revolution. The 2 stroke compression ignition gives way to the traditional four strokes to run its complete cycle. Instead, it merges two strokes into one; thereby making one upward stroke and one downward stroke in every revolution of the crankshaft.

Hence, the 2 stroke cycle engine generates power during each downward stroke of the piston. Thus, it produces double the power output as compared to a 4 stroke cycle engine of the same size. The 2 stroke compression ignition cycle eliminates the suction and exhaust strokes. It uses the only two remaining strokes which are the compression stroke and power stroke. These are known as the upward stroke and downward stroke respectively.
