A REVIEW PAPER ON SIX STROKE INTERNAL COMBUSTION ENGINE

MECHANICAL ENGINEERING

As it is known that four stroke engine have more efficiency than two stroke engine, and further to improve efficiency of four stroke engine and reduce environment pollution, a new concept come up with six stroke engines. Present four stork engine give approximate 30% fuel efficiency and it is expected to give 50% fuel efficiency by six stroke engine. Temperature of a diesel engine reaches to approximate 1400oC which is the main reason of NOx emission so to reduce this we use a secondary fuel below the combustion temperature. In four strokes engine there is four strokes in which for tow revolution of crank shaft there is one power stroke and in six stroke engine there is two power strokes for three revolution of crank shaft. In which second power stroke is more fuel efficient and less pollution produce.
