A REVIEW ON SIX STROKE INTERNAL COMBUSTION ENGINE

Abstract

A Six Stroke Engine is that in which the power is obtained twice in a cycle of six strokes. This engine generates more power with higher fuel efficiency than the existing engines. As a result a new engine concept is formed, which is a six stroke engine. Lot of research work has been conducted on this topic nowadays. In a typical four stroke diesel engine, Piston moves up and down twice in the cylinder during one rotation of crank. The power stroke is obtained once during the two cycles that generates the torque to move vehicle. In Six stroke engine the power stroke is obtained two times out of six strokes. The automobile industry is now seeking for the best six-stroke design which adds one more power stroke which results more efficiency and better utilization of the fuel. The main advantages of six stroke engine are two power strokes in the six stroke cycle, reduction in fuel consumption by 30-40 percent, dramatic reduction in pollution, adaptability to different fuel operation. Development of Six stroke engines by the automobile industry would have a tremendous impact on the environment and economy. The developed six stroke engines, Beare head, Bruce crowers and Velozeta's are undergoing tremendous research works. In this paper the concept, features and the comparative discussion on six-stroke diesel engine is done.
