壁面蒸発式小形ディーゼル機関の断熱化 : 断熱化ピストンの温度分布と燃焼

抄録

Heat insulated pistons were applied to a small size DI diesel engine with the M-combustion system. In this study, two heat insulated pistons were prepared ; one of them was insulated by medium heat, and another by high heat. Experiments on measurements of the combustion chamber surface terperature of each piston, the engine performances and combustion analysis were performed. The test results of each piston are compared and the influences of the piston surface temperature on the engine performances and the combustion characteristics are discussed.
