The most difficult challenge in engine is to increase its thermal efficiency. A conventional four stroke internal combustion engine has very low thermal efficiency because high amount of energy is lost in exhaust and also in cooling of the engine. It is found that about 35% of fuel is lost in exhaust of engine and 30% in its cooling. Out of the remaining 35% of energy, almost 50% of energy is converted into the work. Two additional strokes have to be added to enhance the thermal efficiency which led to development of six stroke engine. In six strokes the engine captures the exhausted heat from the four stroke cycle and uses it to get an additional power stroke and exhaust stroke of the piston in the same cylinder. The main advantages of six stroke engine include a reduction in fuel consumption by 40%, two power strokes in the six stroke cycle, a considerable reduction in pollution and multi-fuel operation. After adopting six stroke engine technology by the automobile industry, it will have a massive impact on the environment and world economy.
