介绍了天然气进气管预混合双燃料发动机的燃料供给系统 ,并对燃料系的控制进行了研究。结果表明 ,采用机械燃料控制系统时双燃料发动机低负荷性能不理想 ;采用电子燃料控制系统时双燃料发动机的动力性、经济性、排放性能比原机有所提高 ,并且使用方便 ,安全可靠
The fuel supply system for the natural gas intake manifold premixed dual fuel engine is introduced. The fuel system control is also studied. The results show that the performance of dual-fuel engine with low load is not satisfactory when the mechanical fuel control system is adopted. The dynamic, economical and emission performance of the dual-fuel engine with the electronic fuel control system is higher than that of the original engine and is easy to use and safe.
