Abstract

This experimental study investigated the effect of pilot injection on combustion characteristics ; specifically combustion noise and soot emission in the low temperature diesel combustion.
Preliminary experiments under wide range of exhaust gas recirculation rate and injection timing were performed to find experimental condition which shows near zero nitrogen oxides emission and maximum indicated mean effective pressure.
In the pilot injection experiment, pilot injection ratio and timing were varied. with fixed pilot injection quantity, more retarded pilot injection timing caused vigorous heat release prior to start of the main injection. It accelerated combustion start of the fuel injected at main injection timing while decreased peak of heat release rate.
Soot emission was increased as pilot injection quantity and timing was increased and retarded, respectively. Maximum pressure rise rate was decreased when the small pilot injection quantity was injected. However, when pilot injection quantity and timing were increased and retarded respectively, maximum pressure rise rate increased even higher than single injection case.
