The effect of a stepped lip piston design on performance and emissions from a high-speed diesel engine

Abstract:

Understanding engine-out NOx and soot emissions from light-duty diesel engines is vital for improving combustion system design and ultimately for reducing aftertreatment requirements. In this work two piston bowl shapes, a standard re-entrant bowl and a bowl with a stepped lip, are tested experimentally and numerically at two part-load operating points (1500 rpm/6.8 bar net IMEP and 1750 rpm/13.5 bar net IMEP), and four full-load operating points (1500, 2000, 3000, and 4000 rpm). The results ...
