INCORPORATION OF EGR AND SPLIT INJECTION FOR REDUCTION OF NOX AND SOOT EMISSIONS IN DI DIESEL ENGINES

ABSTRACT
In this paper, reduced temperature combustion has been investigated at high load condition of a DI diesel engine. A three dimensional CFD model for flow field, spray, air-fuel mixture formation, combustion and emissions formation processes have been used to carry out the computations. The combined effect of EGR temperature and EGR rate was analyzed to choose with consideration of engine performance. Then, the influence of different injection rates and split injection was explored at a reduced temperature combustion condition by the use of EGR. The results represent sensitiveness of various injection schemes on the combustion process and emission formation at reduced temperature condition in DI diesel engines.
