COMPARATIVE STUDY ON THE EFFECTS OF ETHANOL PROPORTION ON THE PARTICLE NUMBERS EMISSIONS IN A COMBINED INJECTION ENGINE

Ethanol has significant potential for the reduction of fuel consumption and the emissions of engines.In this paper, a dual-fuel combined engine test rig with ethanol injected in the intake port and gasoline injected directly into the cylinder are developed and the effects of ethanol/gasoline ratio (Re) on the combustion and emission of particle num
