What is the function of an igniter?

[Skylar]

The function of an igniter is to connect or disconnect the primary circuit of the ignition system based on the ignition signal input from the signal generator, thereby generating the ignition voltage in the secondary winding of the ignition coil. The igniter mainly consists of a power source, ignition coil, distributor, ignition switch, spark plug, additional resistor, and its short-circuit device. Power source: Composed of a battery and generator. During startup, the ignition system is powered by the battery with low-voltage electricity; after startup, when the generator voltage exceeds the battery voltage, the generator supplies low-voltage electricity to the ignition system. Ignition coil: Converts the 12V low-voltage electricity provided by the car's power source into high-voltage electricity capable of overcoming the spark plug electrode gap. Distributor: Driven by the generator's camshaft, it timely connects and disconnects the primary current of the ignition coil, enabling the ignition coil to generate high-voltage electricity promptly and transmit it to the spark plugs of each cylinder in the ignition sequence; simultaneously, it can automatically and manually adjust the ignition timing. The capacitor's role is to reduce the contact spark of the circuit breaker and enhance the secondary voltage of the ignition coil. Ignition switch: Controls the connection and disconnection of the low-voltage circuit of the ignition system and manages the startup and shutdown of the generator. Spark plug: Introduces high-voltage electricity into the combustion chamber to generate an electric spark that ignites the air-fuel mixture. Additional resistor short-circuit device: During startup, the additional resistor is short-circuited to increase the primary current of the ignition coil, thereby enhancing the ignition energy of the spark plug during startup.
