Abstract
A diesel engine has various merits such as high thermal-efficiency, superior fuel consumption and durability. Therefore the number of diesel engine in the world is increasing. As the seriousness of environmental pollution increases in the world, the method to reduce the noxious materials of $CO_2$, NOx and P.M. is very important subject to correspond to exhaust gas regulations. A new concept, so called premixed charge diesel combustion(PCCI), is focused among the various corresponding manners. In this study, we investigated the mixture formation within the cylinder with injection timing using GTT simulation code and also compared combustion characteristics of PCCI engine with that of commercial diesel engine. From this experiments, it could be found that homogeneous mixture formation was observed according to advance of injection timing and simultaneous reduction of NOx and Soot in injection timing of BTDC 60$^{\circ}$.
