防爆柴油机电喷技术的研究

Study on EFI technology of anti-explosion diesel engine

煤矿井下防爆柴油机械存在排放污染和燃油经济性的问题,开发电喷防爆柴油机可以有效解决此问题。文章分析了防爆柴油机的现状,介绍了装在防爆柴油机上的单体泵式和共轨式电控燃油喷射系统的结构和工作原理。

There are problems about emission pollution and fuel economy performance of explosion-proof diesel machinery underground coal mine, and developing EFI explosion-proof diesel engine can well solve this problem. This paper analyses the status quo of diesel engines and introduces the structures and working mechanism of unit- pump and common-rail EFI systems installed in explosion-proof diesel engines.
