Diesel emissions are affected by a variety of factors, such as injection angle, injection pressure, injection whole diameter, injection whole number and spray cone angle and so on. In order to be able to better control the diesel engine at that moment how much emissions and to understand the diesel engine at that moment that the level of emissions. On a L6210ZLC-10 six-cylinder, four-stroke marine diesel engine, by changing the injection advance angle and other conditions unchanged, several groups of comparative tests are done, the average number is taken, and the emission concentration is observed by the control variable method. The effects of fuel injection timing on the emission of CO, Oxo carbon, HC and particulate matter were investigated. The results show that with the increase of injection advance angle, the emission of HC, soot and Co decreases, but the emission of 〖NO〗_xincreases.
