Electronic ignition system introduction
The electronic ignition system is completely different from the mechanical ignition system. It has an electronic control device for ignition, and the internal ignition control curve of the engine under various working conditions. The working state of the engine is judged by a series of sensors such as an engine speed sensor, an intake manifold vacuum sensor (engine load sensor), a throttle position sensor, a crank position sensor, etc., and it is found on the MAP map that the engine is required in this working state. The ignition advance angle is ignited according to this requirement. The above ignition requirements are then corrected based on the knock sensor signal to operate the engine at the optimum ignition timing.
