Abstract
This paper reports on research works of ACE towards the most appropriate injection and combustion system for heavy-duty direct injection diesel engines. Selected items for the study are the effect of nozzle hole diameter, injection rate pattern, swirl ratio, and supercharging under high pressure fuel injection. According to those experimental results, the combination of over 150MPa injection pressure with controlled injection rate, smaller nozzle hole diameter, and quiescent combustion systems shows the best performance and emission. The mechanisms of the combustion improvement are discussed from the turbulent mixing viewpoint, including the results of combustion observation.Keywords
