Summary:

High pressure common-rail injection systems nowadays allow a very high degree of flexibility in the timing and quantity control of multiple injections, which can be used to obtain significant reductions in engine noise and emissions.The aim of this study is to develop a better understanding of the relationship between injection strategies and the combustion and emission formation process.Some multiple injection strategies (pilot-pilot-main and pilot-main-after) have therefore been analyzed to highlight their influence on soot, NOx, combustion noise and bsfc (brake specific fuel consumption) on a passenger car DI Diesel engine prototype.One operating point (20002 rpm/bar) was analyzed for the pilot-pilot-main injection strategy while two operating points (15005 and 25008 rpm/bar) were tested for the pilot-main-after injection strategy.Finally the main combustion characteristics were determined, for each operating condition, on the basis of the heat release and a correlation was attempted between the combustion parameters and emissions, noise and bsfc
