可变喷油规律研究分析

Research and Analysis on Variable Fuel Injection Rates

喷油规律是影响柴油发动机燃烧的重要因素之一,通过控制喷油规律可得到理想的燃烧过程。针对靴型喷射,通过将喷油规律曲线参数化,分析喷油策略对发动机性能的影响,提出优化方案。结合发动机试验,对可变喷油策略进行测试验证。

The fuel injection rate is one of the important parameters that affect the combustion of diesel engines.By controlling the fuel injection rate,an ideal combustion process can be obtained.It selects the boot-type injection,and parameterizes the injection curve.The impact of various injection strategies on different engine speeds and loads is analyzed,and optimization suggestions are proposed.Combined with engine testing,it verifyies the impact of variable fuel injection on combustion.
