The paper aims to highlight the advantages of proposed ideal six stroke internal combustion engine over conventional Otto based four stroke IC engine. The major advantage is 33% fuel savings as compared to four stroke counterpart which is achieved without substantial decrease in the ideal thermal efficiency. The ideal thermal efficiency was found to be 51.99% as compared to 54.499% of four stroke IC engine. The engine operates on a six stroke cycle employing two power strokes, given by fuel-air mixture and water converted to steam. The proposed six stroke internal combustion engine consists of two concentric spheres, such that the combustion of charge takes place in the inner sphere (combustion chamber), while the conversion of water into steam takes place in the outer one. Steam after giving the power stroke is exhausted through a dedicated exhaust valve, and is then recycled using condenser. It is additionally found that apart from the comparable values of thermal efficiency, the proposed six stroke engine promises better power distribution, better fuel combustion and hence lesser emissions.
