Abstract

The control scheme of the LPGdiesel dualfuel engine applying electronic control was discussed,the full load speed characteristics and load characteristics of the LPGdiesel dualfuel engine and the diesel engine were compared, and the road experiment were carried out. The results show that the output performance is not reduced, smoke emission is significantly reduced,NOx emission is hardly changed,HC emission and CO emission are increased,fuel consumption is reduced,and automotive minimum steady speed is not changed.
