A new combustion system for a light duty D. I. diesel engine was developed and introduced (
In this study, in order to clarify the effects of HMMS-III combustion chamber on in-cylinder air motion and characteristics, analysis of flow direction and streak line via oil film method was carried out in comparison with flat dish and re-entrant type combustion chambers. Further, measurement of in-cylinder air motion by L.D.V. and observation of mixture formation and burning process via high speed schlieren photography were carried out.
From these investigations, a particular in-cylinder air motion depending on the configuration of HMMS-III combustion chamber was recognized and the contribution of HMMS-III combustion chamber to in-cylinder air motion and combustion characteristics was clarified.
