[0022] In order to understand the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0023] According to the technical solution of the present invention, a digital ignition method for a small carburetor gasoline engine that adjusts the idle speed, the method adjusts the idle speed of the gasoline engine by adjusting the idle ignition advance angle, so that the engine runs at the target idle speed, that is, according to the actual running idle speed of the gasoline engine The difference between the rotational speed and the target idle speed adjusts the ignition advance angle. When the difference is positive, the ignition advance angle is reduced accordingly. When the difference is negative, the ignition advance angle is increased accordingly. When the control process passes for a period of time After that, the engine speed will fluctuate around a certain average speed, w...
