柴油机的工作过程和各项性能指标,在很大程度上取决于燃油喷射系统的喷油特性及雾化质量。柴油机喷油过程及喷雾过程是紧密相关的两个过程,后一过程受到前一过程的影响与制约。但在已往的计算中很少将两者结合起来进行研究,为了改变这种不合理的传统作法,本文建立了根据喷油过程计算结果进一步计算喷雾过程的统一计算模型,并提出了在高 The working process of the diesel engine and various performance indicators depend largely on the fuel injection characteristics and atomization quality of the fuel injection system. Diesel fuel injection process and spray process are closely related to the two processes, the latter process by the previous process of the impact and constraints. However, in the past calculation, it is seldom to study the two together. In order to change this irrational traditional method, a unified calculation model for further calculating spray process according to the calculation results of injection process is established.
