Combustion of a Diesel Engine with the M-combustion System : Effects of Swirl Ratio 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 (LHR) DI diesel engine with an M-combustion system. In this report, the experiment was performed to investigate the influences of combustion chamber surface temperature and swirl ratio on the combustion of an LHR DI diesel engine with an M-combustion system. It is found that the combustion of deposited fuel on the surface is greatly affected by the combustion chamber surface temperature, and the diesel combustion is controlled by the swirl and the surface temperature of the combustion chamber.
