近年来,一些内燃铲运机配备了德国DEUTZ公司生产的1012或1013系列柴油机,为其提供动力。1012和1013系列柴油机的特点是其直喷系统,1缸1泵,即每个工作缸都有单独的高压油泵。该泵由发动机凸轮轴通过挺柱驱动,喷射压力高(最高可达128 MPa),供油迅速,断油干脆,有利于柴油雾化,燃烧更充分,更彻底,也有利于柴油机实现低排放、低污染、低能耗和高效率的目标。矿山用户在维修过程中经常会遇到高压油泵喷油正时的调整问题。
In recent years, a number of internal combustion scraper equipped with a German company DEUTZ 1012 or 1013 series diesel engine, to provide power. The 1012 and 1013 series diesel engines feature direct injection, 1 cylinder 1 pump, ie a separate high pressure pump for each cylinder. The pump driven by the engine camshaft driven by tappets, high injection pressure (up to 128 MPa), rapid fuel supply, off the oil simply, is conducive to diesel atomization, combustion more fully and thoroughly, but also conducive to diesel engines to achieve low emissions , Low pollution, low energy consumption and high efficiency. Mining users in the maintenance process often encounter high-pressure pump fuel injection timing adjustment problem.
