1 前言 近年来,随着国家对环保要求的提高,相当于欧Ⅰ、欧Ⅱ排放法规的逐步实施,对国内柴油机性能要求也不断提高。一方面油泵高压喷射可以改善柴油机性能、降低排放。另一方面,对调速器控制喷油量的作用也提出了更高的要求。我厂生产的RLD型机械调速器正是为进一步满足这种要求而开发设计的。
1 Introduction In recent years, with the national environmental protection requirements increase, equivalent to the gradual implementation of the European Ⅰ, European Ⅱ emission regulations, the domestic diesel engine performance requirements are also rising. On the one hand, high pressure injection pump can improve diesel engine performance and reduce emissions. On the other hand, the governor to control the effect of fuel injection also put forward higher requirements. RLD mechanical governor produced by our factory is designed to further meet this requirement.
