摘　　要： 对发动机临界爆震的控制特性进行了试验研究,得出了最佳点火提前角控制曲面。由爆震判别可知,各缸爆震程度差异性较大。对近爆震区域的发动机的动力性和经济性进行了试验研究。指出在接近爆震区域,动力性和经济性均有改善趋势。发现爆震控制系统存在调节惯性,并对此进行了一定的分析。 Control characteristics of critical knock of S.I.engine have been experimentally investigated,and optimal ignition advanced angle surface of engine controlled by a knockcontrol unit has been obtained.Knock identification told of difference in knock intensity from cylinder to cylinder.Power output and fuel economy of engine under control of knockcontrol unit were tested and results prove that performances can be improved when engine approaches critical knock conditions.It is found that adjustment inertia exists in adjusting process of the knockcontrol system and its effect was discussed.
