天然气-柴油双燃料发动机减油技术研究

Research on Pilot Diesel’s Control Technology of Natural Gas-Diesel Dual Fuel Engine

机动车排放污染已经成为城市大气污染的主要来源之一,在机动车推广使用天然气替代燃料技术是减少大气污染的有效措施之一。对于部分农用机械,机械泵式柴油机仍是主要动力来源,改装成天然气-柴油双燃料发动机时如何通过加装减油机构控制喷油量成为了一个研究重点。文章针对国内某款柱塞泵式柴油机的减油机构进行设计和研究,对农用机械的改装具有参考意义。

Vehicle emission pollution has become one of the main sources of urban air pollution.For some agricultural machinery,the mechanical pump diesel engine is still the main power source,so how to control the amount of fuel injection by adding diesel reduction mechanism becomes a research focus when refitted into a natural gas-diesel dual fuel engine.In this paper,the design and research of a plunger pump diesel engine a diesel reduction mechanism are carried out.
