摘　　要：这是为改进喷油嘴喷孔夹角与燃烧室形状间的匹配而提出的一种喷孔夹角设计与计算方法。通过在R100系列柴油机上的试验,证实了采用优化设计的喷油嘴能有效地降低燃油消耗率和排气烟度。为直喷式柴油机燃烧室与喷油嘴的合理匹配提供了一条有效途径,对直喷式柴油机性能改进和提高起到重要作用。Design and test are presented in this paper for the purpose of matching the nozzle spray angle with combustion chamber shape. Test results from the R100 diesel engine show that the optimized fuel injection nozzle angle can improve the fuel consumption rate and emissions effectively. It can be a effective way to be offered to optimize the matching of combustion chamber with injection nozzle for direct injection engine. It is of importance to the improvement of direct injection engine performance.
