摘　　要：在分析调节配气定时参数降低燃油消耗及减少排放机理的基础上,对比了进气门定时单独连续可变,排气门定时单独连续可变,进排气门定时联动连续可变及进排气门定时独立连续可变4种可变气门定时技术对汽油机性能的影响,并给出了其在汽油机上的应用策略。最后,使用这种策略对配有进排气门定时独立连续可变技术的汽油机进行了气门定时优化试验,并分析了试验结果。Based on the fuel consumption and emission reduction by adjusting the valve timing, the intake valve variable tim ing, the exhaust valve variable timing,intake and exhaust valve simultaneous variable timing and their separate variable timing were compared, their influences on gasoline engine performance were analyzed and their application strategies on gasoline engine were acquired. Finally, with the strategy, the valve timing of gasoline engine with the intake and exhaust valve separate varia- ble timing was optimized and the experimental results were analyzed.
