。 A pulsar that outputs a signal in response to the rotation of an internal combustion engine.
To send a voltage spark to the spark plug of an internal combustion engine 2
An ignition coil whose next side is connected to the spark plug, a power transistor that controls the flow and cutoff of the primary side current of the ignition coil, and an ignition position that is calculated based on the pulser signal and controls the flow and cutoff of the base current of the power transistor. A non-contact ignition system for internal combustion engines, which consists of a control circuit, detects the power supply voltage level and fixes the ignition position at the initial position when the voltage level drops below a specified value. A non-contact ignition device for an internal combustion engine, characterized in that the ignition position continues to be fixed at the initial position for a certain period of time after returning.
