HEV electric system may limit the working area of the engine to reduce fuel consumption and reduce emissions.

混合动力汽车动力系统中有电动系统参与工作,从而可以限制发动机的工作区域,以减少油耗和降低排放。

The results of fuel economy simulation of a mild HEV at NEDC cycle shows that the decrease of fuel consumption is remarkable compared to the conventional vehicle.

轻度混合动力汽车在NEDC循环工况的燃油经济性仿真表明,与传统的基础车型比较,并联型轻度混合动力系统的燃油消耗显著降低。

To make full use of the auto-power and economy,the characteristics of the air intake and fuel consumption for gasoline engine’s excess air ratio have been studied which are in the fixed load and speed.

为了充分发挥发动机的动力性和经济性,研究了定负荷和定转速下汽油机过量空气系数的进气和燃油消耗特性。
