SW400/L 柴油机为四冲程、直喷式燃烧室、六缸发动机,额定功率115马力。柴油机工作的好坏,除其它因素外,一部份取决于喷油器的喷射压力及油束的雾化。喷射压力过高,容易引起柴油机敲缸,同时也容易使喷油泵柱塞偶件和喷油器偶件过早磨损。喷射压力过低,将使喷油的雾化情况变劣,同时柴油消耗 SW400 / L diesel engine for the four-stroke, direct injection combustion chamber, six-cylinder engine, rated 115 hp. The performance of a diesel engine depends, among other things, on the injection pressure of the fuel injector and the atomization of the fuel bundle. Injection pressure is too high, easily lead to knocking cylinder diesel engine, but also easy to make injection pump plunger and injector coupling premature wear. Injection pressure is too low, will make the fuel spray atomization worse, while diesel consumption
