| 摘 要： | 对单缸柴油机双喷油器直喷燃烧系统进行了研究，分析了供油系统油管分叉夹角及截面收缩比、燃烧室油线布置及几何形状的优化原则。采用该燃烧系统，可增加燃油喷注在燃烧室内的自由贯穿长度，减少对进气涡流的依赖，促进混合气形成和燃烧；可降低气缸盖及活塞的热负荷；由于进、排气门中心线与气缸中心线处于同一平面，故气门流通面积大，可以改善进排气流动性能；可实现先缓后急的喷油规律。

| Abstract: | The analysis of duel-fuel combustion system of a diesel engine was made and the characteristics of the duel fuel combustion process were introduced. The optimizations of its fuel supply, the angle of divided fuel supply pipe, the spray line in the combustion chamber and the geometry of the combustion chamber were made. The improved combustion system increases the length of fuel spray, decreases the air swirl ratio and promotes the gaseous mixture formation and the combustion process, all of which led deduction of the heat loads of the cylinder head and the piston. The fuel injection speed was regulated by moving inlet and exhaust port to the center line of the cylinder. |
