缸内直喷汽油机燃油喷雾特性影响因素试验研究

Experimental Research on Effect Factors of Spray Characteristics for Gasoline Direct Injection Engine

在喷雾试验装置基础上,利用高速摄影技术研究了喷射压力、背压、喷油脉宽对缸内直喷汽油机多孔喷油器喷雾特性的影响。

Based on spray testing equipment, the injection pressure, gas backpressure and injection pulse width affecting the spray characteristics for multi-hole injector of gasoline direct injection engine were studied with high-speed photography.
