APPLICATION OF FUEL SPRAY THEORY TO EXHAUST EMISSION CONTROL IN A D.I. DIESEL ENGINE

From the theoretical analysis of fuel spray motion in the quiescent air and the photographic study of the fuel spray combustion, it was found that higher rate of air entrainment into the fuel spray by its own kinetic energy gives a very important effect on the increasing of combustion efficiency in the diesel engine and the reduction of soot formation. So, we designed the high volumetric efficiency but low swirl generating intake port in order to charge sufficient air into the cylinder and an improved fuel injection system to attain high injection rate and high injection pressure so as to obtain high cycle efficiency and good fuel-air mixing in the quiescent air. /GMRL/
