本文研究了柴油机轴针式喷油咀喷雾部分的结构参数对喷油咀喷雾状况的影响。研究结果表明:喷油咀的座面密封性和针阀轴针在喷孔内的长度是影响喷油咀喷雾状况的两个重要因素,并提出了改善座面密封性和喷雾状况的途径以及生产中应采取的相应措施。
In this paper, the influence of the structural parameters of the injector part of the diesel engine pin injector nozzle on the spray condition of the injector nozzle is studied. The results show that the sealability of the injection nozzle and the length of the needle pin in the spray hole are two important factors affecting the spray condition of the nozzle, and the ways to improve the seal and spray conditions of the seat are proposed. The corresponding measures to be taken in production.
