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.
In the control system of engine, the control of electronic control ignition equipment to the engine ignition consists of the following 3 parts: advanced ignition Angle, conduction time and detonation.
