The control of ignition advance Angle is mostly open-loop control and the control data is obtained from experiment. Close-loop control method is applied to avoid engine knock.
对点火提前角的控制主要是开环控制，控制数据由试验得到，对爆震现象采取了闭环控制。
Secondly, the control strategy of Electronic control System is analyzed, including fuel-air ratio control and ignition advance Angle control.
其次，分析了电控系统的控制策略，包括空燃比控制和点火提前角控制。
