Abstract

The main purpose of this study is to investigate the effects of exhaust gases on different combustion modes in DI, Direct Injection, compression ignited engines in terms of combustion efficiency and emission formations. The conventional parametric Φ -T (Equivalence Ratio-Temperature) emission map analysis has been extended by constructing the transient maps for different species characterizing the combustion and emission formation processes. The results of the analysis prove the efficiency of different combustion modes when EGR loads and injection scenarios. Copyright © 2007 SAE International Inc.
