EXPERIMENTAL ASSESSMENT OF AN AIR-GAP COPPER CROWN PISTON FOR ENHANCED PERFORMANCE AND REDUCED EMISSIONS IN A METHANOL–DIESEL FUELED CI ENGINE

Abstract

All over the world use of petroleum products has been increasing tremendously. This has resulted in scarcity of fuel for internal combustion engines and the problem has become acute during the recent years. The present fossil fuels may get exhaust in another 30 to 40 years. The cost of fossil fuels increasing day by day. The emission caused by these fossil fuels, made us to think of alternate fuels for IC engines. These alternate fuels may be alcohol and vegetable oils. This paper presents experimental work on use of methanol blends with diesel in CI engine andoxidation of aldehydes emission in exhaust gases during combustion itself using un-conventional catalytic converter asair gap copper crown piston in the CI engine. The result shows that there is a marginal increase in Brake thermal efficiency
