Engine performance is expressed in terms of brakethermalefficiency.
发动机的性能表现在刹车的热效率。
2
However, the brakethermalefficiency increases and the CO emissions almost equal at high loads.
高负荷时发动机有效热效率增加而CO排放基本相当。
3
Under the load characteristic of operation, the brake specific fuel consumption and effective thermalefficiency is almost similar to that of gasoline engine.
