以简略地看成是汽油机和柴油机的混合体,具有多种燃料的包容性。其工作原理见图1。HCCI燃烧后的排出物基本上不含有颗粒物和氮氧化物的原因是:燃料在混合气体中的配量少并且十分均匀,在燃烧室中不会有局部的过浓混合气体,从而不会产生颗粒物;当燃烧温度达到2 000 ℃时,NOx的产
It is briefly considered as a mixture of gasoline engine and diesel engine, with a variety of fuel inclusions. Its working principle shown in Figure 1. The reason why the HCCI-combusted effluent is substantially free of particulate matter and nitrogen oxides is that the fuel is mixed in the mixed gas in a small and uniform manner so that there is no local excess rich gas in the combustion chamber so that it does not occur Particles; NOx production when combustion temperature reached 2 000 ° C
