A Study on HCCI combustion engine using a gasoline-DME mixed fuel

摘要

The main purpose of the study is to investigate the ideal manner and ratio to inject gasoline and DME simultaneously into intake port, and moreover to confirm the characteristics of combustion and emission of engine. Experimental conditions are 1200 rpm, compression ratio 8.5, intake air temperature(l10 °C). Internal cylinder pressure was collected to confirm the characteristics of combustion in order to calculate the heat release rate in the cylinder. In addition, HORIBA (MEXA 7100) which was possible analyzing emissions(NO_x, CO, HC) was used. Vanguard gasoline engine (23HP386447) was used in this experiment.
