Abstract

The main purpose of this study is to apply the parametric φ-T (Equivalence Ratio-Temperature) map analysis coupled with 3D engine simulations to characterize different combustion modes in DI, Direct Injection, compression ignited engines in terms of combustion efficiency and emission formations. The conventional static map analysis has been extended by constructing the parametric maps of a dynamic nature for different species characterizing the combustion and emission formation processes. The results of the analysis prove the efficiency of different combustion modes when injection parameters were varied from early to retarded injections.
