A NEW APPROACH FOR UTILISATION OF LPG - DEE IN HOMOGENEOUS CHARGE COMPRESSION IGNITION (HCCI) ENGINE

Diethyl Ether (DEE) is a significant component in a blend or as a complete replacement for diesel fuel. The presence of smoke in the diesel engine exhaust is an indication of poor combustion due to so many reasons. Nevertheless with increasing concern for the effect of air pollution on the environment, animal and plant life, particularly in road transport, vehicle exhaust emissions have in recent years been subjected to increasingly stringent regulations. A novel way of approaching in this direction is utilization of LPG in direct injection Diesel engine as a fuel with DEE as an ignition enhancer. This paper reports on the study of performance and emissions characteristics in a four stroke, 3.7 kW, single cylinder, DI diesel engine on homogeneous charge compression ignition mode (HCCI).
