| 摘 要： | 对不同的进气温度、燃料辛烷值和燃空当量比对均质压燃(HCCI)发动机的排放特性进行了研究。研究结果表明,随着进气温度的提高和燃空当量比的增大,HC和CO排放逐步减少,而NOx排放一直较低;低进气温度下,燃料的辛烷值对HCCI发动机的排放影响较大,辛烷值越大,HC和CO排放量越大,NOx排放值突增拐点的燃空当量比越大;高进气温度下,燃料辛烷值对HC和CO排放的影响很小,燃空当量比对NOx排放值出现拐点的影响作用基本消失。

| Abstract: | The HCCI engine emissions characteristic is studied by different temperature and different fuel octane number.The results show that HC and CO emissions decrease with the increase of intake temperature and mixture density,NO_x emissions is always low.The HC and CO emissions increase with the increase of fuel octane number and fuel and air equivalent ratio of suddenly increase NO_xemissions is increase at lower intake temperature.Compared with the lower intake temperature,the effect of fuel octane number on emissions is little in the higher temperature |

| Keywords: | ICE HCCI intake temperature octane number emission control |
