摘要 均质混合气压燃(HCCI)燃烧受爆震和NO_x排放的限制,高负荷拓展是一个难题。本文提出利用理论空燃比SICI组合燃烧作为汽油机中高负荷运行区域的高效低污染燃烧模式。在试验台架上研究了理论空燃比SICI组合燃烧的排放特性及其对三效催化剂(TWC)转换性能的影响。研究发现,通过外部EGR与点火控制相结合,理论空燃比SICI组合燃烧可以在指示平均有效压力(IMEP)0.65～0.82MPa范围内稳定实现;与传统SI燃烧相比,理论空燃比SICI组合燃烧燃油经济性提高近10%,NO_x排放降低80%以上,但HC排放有所增加;SICI组合燃烧与传统SI燃烧类似,TWC空燃比特性的高效区间在理论空燃比附近,但对HC排放的催化能力提出了更高的要求。 Homogeneous Charge Compression Ignition（HCCI） has challenge of high load extension. This paper took stoichimetric spark induced compression ignition（SICI） combustion mode as the method to extend the high load of HCCI,studied the emission characteristics of stoichimetric SICI and evaluated the performance of three way catalyst under such combustion mode.The results show that SICI can be stably realized during the region of IMEP 0.65-0.82 MPa by the combination control of external EGR and spark ignition.The fuel economy of SICI is increased by 10%,the NC_x emission is decreased by 80%but the HC emission is increased.The high conversion efficiency region of the TWC is similar to SI combustion,but the requirement for HC conversion ability increases.
