Combustion of a diesel engine with the M-combustion system (Effects of injection direction and surface temperature of combustion chamber).

Abstract

This paper gives the experimental results obtained with a two stroke cycle single cylinder research engine using an electrically heated combustion chamber to simulate the combustion chamber of a low heat rejection DI diesel engine with an M-combustion system. In this report, the experiment was performed to investigate the influences of fuel injection direction, which is cosidered to affect the quantity of deposited fuel on the combustion chamber surface and the influences of combustion chamber surface temperature on the diesel combustion. It is found that the combustion chamber surface temperature greatly affects the combustion of deposited fuel on the surface, and the diesel combustion is controled with the injection direction and the surface temperature of the combustion chamber.
