Under the load characteristic of operation, the brake specific fuel consumption and effective thermalefficiency is almost similar to that of gasoline engine.
在负荷特性工况运行时，混合燃料发动机的有效燃料消耗率和有效热效率与汽油机基本相当；
2
Engine performance is expressed in terms of brakethermalefficiency.
发动机的性能表现在刹车的热效率。
3
However, the brakethermalefficiency increases and the CO emissions almost equal at high loads.
