The optimization and matching question for the low-speed diesel engine’s combustion process determines its power, efficiency and emission. But the optimization and matching of the combustion process is related with the fuel injection rule, the intake swirl control, the valve timing adjustment, the combustion chamber structure, the operating condition parameter and so on. This paper takes the 5S60 marine low-speed diesel engine as the study object. The whole running phase oriented model based on the unified multi-domain has established, and the analysis for the diesel engine’s combustion process in cylinder has carried on. The analysis result provides the technical support for the economical, safe and reliable operation of the diesel engine. Thus the combustion process in cylinder is improved, the diesel engine’s performance is enhanced, and the pollutant discharge is reduced.

Mustard Methyl Esters (further biodiesel) and regular diesel fuel were tested in direct injection diesel engine. Analysis of experimental data was supported by an analysis of fuel injection and combustion characteristics. Engine fuelled with biodiesel had increased brake specific fuel consumption, reduced nitrogen oxides emission and smoke opacity, moderate increase in carbon monoxide emission with essentially unchanged unburned hydrocarbons emission. Increase in fuel consumption was attributed to lesser heating value of biodiesel and partially to decreased fuel conversion efficiency. Analysis of combustion characteristics revealed earlier start of injection and shorter ignition delay period of biodiesel. Resulting decrease in maximum rate of heat release and cylinder pressure was the most probable reason for reduced emission of nitrogen oxides. Analysis of combustion characteristics also showed that cetane index determined by ASTM Method D976 is not a proper measure of ignition quality of biodiesel. Conclusion was made on applicability of mustard oil as a source for commercial production of biodiesel in Pakistan. Potentialities of on improving combustion and emissions characteristics of diesel engine by reformulating biodiesel were discussed.
