以柴油机为原型,增加了天然气供气系统,开发了天然气/柴油双燃料发动机。采用闭环控制系统对天然气进气量进行实时控制,发动机采用双阶段双燃料模式运行,实现了全负荷工况下天然气对柴油85%左右的替代率,在保持原机动力性的基础上实现了良好的经济性。

A diesel engine is modified to a nature gas/diesel dual-fuel engine,where a nature gas supply system is supplied.A closed loop controller is applied to realize the real-time control to the nature gas flow.The engine is operated in the mode of dual-stage and dual-fuel combustion,bringing better fuel economy and dynamics.85% diesel is replaced with nature gas.
