摘　　要：探讨了喷油嘴四孔流量分布对燃油喷雾和柴油机性能的影响。结果表明,不正常的流量分布可以改变喷雾的形状及各孔油束的射程,导致燃油在燃烧室中分布情况恶化,从而使柴油机性能,特别是在低速大负荷工况下的性能下降。The influence of injector Nozzle four orifices flux distribution on fuel spray and ZH1105 diesel engine is studied in this paper. The experiment results show that abnormal flux distribution can change the shape of spray and fuel spray lengths of every bundle, influence the oil uniformity in combustion chamber, make ZH10105 diesel engine worse performance, especially at low speed and heavy load.
