メタノールDIエンジンの着火・燃焼に関する化学反応速度論的検討 : 第2報, 排出ガス生成過程の解析〔熱工学, 内燃機関, 動力など〕

A numerical model has been developed for predicting exhaust gas emissions including NOx HCHO, CH3OH and other chemical species in a direct injection diesel engine fueled with methanol. In this model, 39 species with related 157 elementary reactions are taken into account. The effects of air excess ratios and load conditions on the exhaust gas emission characteristics were investigated based on this kinetic model. The model can predicts the formation and destruction of chemical species in the combustion process and the formation of formaldehyde and NO2 during the expansion stroke.
