Abstract

Generally, soot emission is increased in smaller-size bore diesel engine than larger one because spray-impingement on cavity wall is more significant, while keeping at constant specific output power. In the first report, it has been confirmed that soot is still increased even using smaller nozzle orifice proportional according to bore-size reduction so as to avoid excessive spray-wall impingement, compare to larger-bore engine. It has been considered that soot increase is caused by decreasing air entrainment due to shrinking of spray angle.
