Abstract

The effects of the combined use of exhaust gas recirculation (EGR) and multi-hole injector with pilot injection on combustion and emissions were investigated on a small direct injection diesel engine equipped with a common-rail injection system. Tests were performed at fixed engine speed (800 rpm) under idling condition with various EGR ratios (0 to 50 %) and the injection pressures (60, 120 MPa) versus two different nozzle hole numbers (5, 14 holes). The results showed that significant improvements in power output and the simultaneous reduction of NOx and PM could be achieved when pilot injection was applied with 14-hole injector and EGR.
