摘　　要：综述了配气正时对增压发动机动力性及经济性的影响,通过改变进排气门开启与关闭时刻力图找到不同工况下的最优配气正时并改善发动机增压以后带来的热负荷加重等不利影响。The effects of valve timing on the dynamics and economy of supercharged engines are reviewed. By changing the opening and closing timing of intake and exhaust valves, we can find the optimal valve timing under different working conditions and improve the adverse effects of engine after boosting such as increased heat load.
