5 Stroke engine-a revolutionary pathway for efficient engine performance

During the past three centuries, there has always been an emphasis on development of a kind of engine that has superior efficiency is less polluting and has good power generation. This review paper describes the new advancement in the four stroke Internal Combustion Engine (ICE) which has enormous advantage. For further improvement in IC engines, a Belgium Engineer name Gerhard Schmitz presented a new innovation called five stroke Engine. This concept gained momentum and its prototype was put in reality by Ilmor Engineering. After considering research, it was developed with the idea of generating expansion ratio significantly higher than compression ratio. This engine has a similar torque generation and high power density but low fuel consumption when compared with the Four-stroke engines. The total efficiency is improved in the certain range.
