New combustion and fuel technologies were applied to a multi-cylinder diesel engine to improve both emission and fuel consumption of a diesel engine. Performance of the multi-cylinder engine with 3-stage turbocharging system was investigated with JIS#2 diesel and optimum fuel derived from a previous study to determine engine control parameters for each fuel. The results shows that emission (NOx < 0.2 g/kWh, PM < 0.01 g/kWh) and fuel consumption (10% improvement) targeted in this study could be achieved with both JIS#2 and optimum fuel. And especially it's clarified that the optimum fuel can simultaneously reduce NOx and PM in contrast to the conventional fuel.
