Which contacts in the traditional ignition system are eliminated by the electronic ignition system?

Circuit breaker contact. The most basic function of electronic control ignition system (ESA) is to control the ignition in advance. According to the signals of relevant sensors, the system judges the working conditions and conditions of the engine, and selects the most ideal ignition advance angle to ignite the mixture, thus improving the combustion process of the engine, and achieving the purposes of improving the engine power, economy and reducing emission pollution. The ignition controller in the electronic ignition system replaces the contact of the traditional interruption device of the ignition system, shapes and amplifies the ignition signal output by the ignition signal generator, converts it into an ignition control signal, and controls the on-off of the current in the primary winding of the ignition coil, thus generating high-voltage electricity in the secondary winding for spark plug ignition.
