摘要
在本研究中，利用分析技术对喷油器进行了基于燃料和喷嘴的形状优化。作为分析条件，入口流速为0.08 kg / s，出口流速为0 Bar。对每种燃料使用不同的工作液。通过分析可以看出，在柴油机中，修改叶尖后的模型的压力和速度都要高于基础模型。在汽油情况下，与基本模型相比，改进后的喷嘴模型在燃烧室压力和燃油直线度方面具有更稳定的喷射特性。最后，以LPG喷油器为例，发现与汽油相同的修饰尖端是更稳定的喷油器。在此研究结果的基础上，可以推断出喷油器的形状参数。
In this study, the shape optimization of the injector according to fuel and tip was conducted through analytical techniques. As an analysis condition, a flow rate of 0.08 kg / s was applied to the inlet and the outlet was given a condition of 0 Bar. The working fluid for each fuel was applied. As a result of the analysis, it can be seen that the pressure and velocity of model with the modified tip become higher than that of the base model in diesel. Compared with the base model in the case of gasoline, the modified model of the tip was found to have more stable injection when the pressure inside the combustion chamber and the straightness of the fuel were observed. Finally, in case of LPG injector, the same modified tip as gasoline was found to be the more stable injection. On the basis of this study result, the shape parameters of the injector can be inferred.
