摘　　要：当代新型船用柴油机的高压油泵都配备了VIT机构,它能根据负荷的变化自动调节供油提前角,以提高最高爆发压力同时又限制最高爆发压力,来改善柴油机的经济性和提高可靠性。文章根据VIT机构的工作原理,并结合其调节特性,总结出了VIT机构的调节方法,以此实现主机降速节能的措施。VIT structures are fitted for the high-pressure oil pumps in marine new-type diesel engines, which can adjust the oil-supply pre-angle automatically according to the change of loading in order to achieve both raising the highest bursting pressure and restricting it. This may improve the diesel engine with its economy and reliability. This paper concludes the adjusting method for realizing moderating energy-saving of main engine, with VIT working principle and its regulating character.

关 键 词：VIT机构 降速节能 最高爆发压力 拐点
