There are many factors that affect engine emission performance, such as fuel supply advance angle, fuel type, gasification temperature and fuel injection parameters, etc. In order to be able to know exactly how much the engine that period of emissions and the engine that period of fuel injection pressure can reduce the concentration of certain emissions. In this paper, a six-cylinder, four-stroke marine diesel engine L6230ZLC-10 is tested by control variable method by changing injection pressure and other conditions unchanged. The effects of engine injection pressure on emissions of carbon monoxide, Oxo carbon, hydrocarbon and particulate matter were investigated. The results show that with the increase of fuel injection pressure, the emissions of soot and carbon monoxide decrease, and the emissions of nitrogen oxide increase slightly, and the emissions of hydrocarbon decrease first and then increase, but the overall decrease is dominant. By changing the injection pressure, the soot emission is greatly affected.
