Relation Between Fuel Supply Advance Angle of Swirl ChamberDiesel Engine and Working Process and Noise

This paper applied the method of experimentation and simulation calculation to analyzing the disciplinarian of swirl chamber diesel engine's working condition and noise along with the variation of fuel supply advance angle,making use of a N485 diesel as sampling engine.The investigation declared that there is an optimum fuel supply advance angle in a certain working condition,that can make the whole performances reach the optimum engineering values,and offered a method how to ascertain the optimum fuel supply advance angle accurately.
