摘　　要：在ＣＡ１１０２单缸汽油试验机上测量采集了不同工况、不同爆震强度时的压力示功图，用国外现有的７种爆震强度评价指标对已测得的数据进行了计算分析，阐述了各种指标的优缺点及用于汽车发动机实时控制的可能性。The indicator diagrams of different operating conditions and knock intensities were measured on a single cylinder gasoline test engine. On the basis of seven indices used abroad for evaluating knock intensity, the calculations and analyses were carried out on the measured data. The advantages and disadvantages of various indices and the possibility of real time knock control used for automotive engines are known clearly.
