Measurements and Investigations on Combustion and Heat Transfer in Diesel Engines

Abstract

The results of investigation for the relation between fuel/air mixture formation in near-field of Diesel spray flame and combustion characteristics, and those of investigation for the heat transfer in Diesel combustion are reported. The rapid compression machine coupled with special designed combustion chambers is use for these investigations. Obtained results show that the mixture formation in the near-field of spray affects strongly the emissions from Diesel combustion, and that the heat transfer of Diesel combustion can’t be described by the conventional heat transfer models which are based on the heat transfer in steady impinging single phase jets.
