抄録
In order to investigate the effects of mixture Inhomogeneity and gas flow on combustion and emissions in a premixed-charge compression ignition engine, three-dimensional numerical analysis of the combustion process was carried out by using the authors' GTT-CHEM code, which was linked to the CHEMKIN-II code. Combustion processes of gas oil and air mixtures (overall equivalence ratio was set at 0.4) under various initial conditions of mixture inhomogeneity and gas flow (swirl or tumble flow) were computed in consideration of chemical kinetics. It has been found that the maximum rate of pressure rise decreases as the mixture inhomogeneity becomes higher. On the contrary, the concentrations of combustion products NO, CO and HC increase, and the combustion efficiency becomes lower with the increase of mixture inhomogeneity. As a result, it has been shown that there exist appropriate initial conditions of mixture inhomogeneity and gas flow for suppressing the maximum rate of pressure rise with relatively low emissions of NO, CO and HC at high combustion efficiency.
