| 摘 要： | 对柴油机进行燃烧噪声随各种供油系统参数变化的实验研究,详细地分析和研究了燃烧噪声与气缸压力升高率双峰特性之间的关系,研究表明,第二峰值是燃烧噪声的表征量,燃烧噪声主要是柴油机负荷的函数．同时利用双弹簧喷油器研究了预喷射对燃烧噪声的影响,证明双弹簧喷油器情况下的压力升高率也存在双峰特性．

| Abstract: | Based on the experiment, the combustion noise variation of a vehicle diesel with parameters of pump and injector were analyzed, the relationship between combustion noise and the double-peak rise rate of cylinder pressure were analyzed carefully, some conclusion such as the second peak is the token of combustion noise and combustion noise is the function of diesel load were got. At the same time, the inflution of double-spring injector to combustion noise was studied and the double-peak rise of cylinder pressure is also exist. |
