Advanced Injection Strategies to Attain Partially Premixed Combustion Process in a Heavy Duty Diesel Engine 2008-01-0642

The scope of present study is the analysis of the potential of the highly premixed combustion concept for pollutant control in a HD Diesel engine. Two different approaches to attain this advanced combustion concept are presented in this paper. A narrow angle nozzle configuration is investigated with two different adapted piston bowl geometries. Parametrical tests were performed in a HD single cylinder engine with the aim of appreciating advantages and limitations of these strategies. In each case, results are compared with equivalent conventional single injection strategy. This analysis is focused on NOx-soot emissions and also on engine performance.
