为了探索汽油发动机节气门开度变化率对发动机动力性的影响，通过发动机台架试验，研究了低转速、中转速、中高转速下不同节气门开度变化率对汽车变矩时间长短、变矩过程缓和程度的影响及与变矩结束时刻发动机瞬时转矩大小的关系。结果表明，在不同节气门开度变化率情况下，发动机动力性能指标有所不同，同时发动机转速越高，节气门开度变化率对其动力性影响越小。
為瞭探索汽油髮動機節氣門開度變化率對髮動機動力性的影響，通過髮動機檯架試驗，研究瞭低轉速、中轉速、中高轉速下不同節氣門開度變化率對汽車變矩時間長短、變矩過程緩和程度的影響及與變矩結束時刻髮動機瞬時轉矩大小的關繫。結果錶明，在不同節氣門開度變化率情況下，髮動機動力性能指標有所不同，同時髮動機轉速越高，節氣門開度變化率對其動力性影響越小。

To summarize the influence of variance ration of the throttle opening on gasoline engine perform-ance,some engine bed tests were done including study on the impact of length of torque time ,the cushion of torque converter process under different variance ration of the throttle opening with a constant speed and the study on the relationship between the torque on the end of the torque moment .The result showed that the dif-ferent variance ration of throttle opening led to different engine dynamic performance indexes and at the same time with the increase of engine speed ,the influence exerted by variance ration of throttle opening on the en-gine performance became less .
