Modification and Performance Energy Analysis of Four Stroke Engine to Six Stroke Engine
Modern four stroke engines are used on large scale because the power to weight ratio and reliableness of four
stroke engines are greater. The disadvantages of the four stroke engine are that there is excess amount of heat energy
produced. This heat energy has been wasted through the walls of the container of the engine and ejected as the additional
energy during the exhaust stroke of the cycle. To increase the efficiency of the 4 stroke engine there is need to develop a six
stroke internal combustion engine which uses the heat energy for additional power stroke. So to raise the brake thermal
efficiency of the engine, few of the fundamental changes have been performed in four stroke internal combustion engine.
The changes are also made to reduce the pollution and for better scavenging.
