main oil way pressure limiting valve

The structure of a type of BOSCH fuel pressure limiter for common rail diesel engine has been described and analyzed.

描述和分析了一种BOSCH共轨燃油限压阀的结构,明确了阀座三级中孔等关键结构的作用,限压阀阀座上采用三种不同直径的中孔,可起到迅速泄压、缩小限压阀体积和节流的作用,并通过试验进行了验证。

Experiments of pressure limiter as one part of common rail pipe were carried out in the paper based on the study of high-pressure common rail system, and experiment results were analyzed too.

在电控高压共轨系统研究的基础上,对共轨管部件限压阀进行了试验研究,并对试验结果进行了分析,最后对自主开发的限压阀特性进行试验,并提出压力控制故障模式下的程序运行流程,从而为共轨系统故障诊断奠定了基础。
