THE EFFECTS OF EGR AND SPLIT FUEL INJECTION ON DIESEL ENGINE EMISSION
Z. GAO,W. SCHREIBER 한국자동차공학회 2001 International journal of automotive technology Vol.2 No.4
An important goal in diesel engine research is the development of a means to reduce the emission of oxides of nitrogen (NO_x) and soot particulate. A phenomenological model based on the multizone concept is used in the current paper to analyze and compare the effects of exhaust gas recirculation (EGR) and split fuel injection on emission from a compression-ignited, direct-injection engine. The present results show that NO_x can be reduced with a minimum penalty of soot particle emission with cooled EGR. Compared with EGR, split fuel injection has a higher soot penalty at a given level of NO_x reduction.<br/>
