摘　　要：为将纯柴油发动机改造为LNG/柴油双燃料多点顺序喷射发动机,在不改变原型机结构前提下设计了一套天然气供给系统。为验证该供气系满足否满足原型机在额定工况下的需求,设计了进气道喷射模拟试验台。试验验证表明:该天然气供给系统能够满足发动机在额定工况下燃气供应量及喷射控制的需求,且整套系统能够根据发动机不同工况调整天然气的喷射量。试验结果可为发动机在双燃料模式下运行提供前期数据支撑。To transform diesel engines into multi-point sequential injection LNG/diesel dual fuel engines, the natural gas supplying system maintaining the structure of prototype was developed. To verify if this system could meet the requirements of the prototype under rated condition, the test bed for the simulation of inlet pipe injection was designed. The test results show that the natural gas supplying system could sa- tisfy the gas supply volume under rated condition, as well as the requirements of injection control. More- over; the whole system could adjust natural gas injection volume according to varied engine working con- ditions. The research results provide reference data for engine operated under dual fuel mode.
