タ。In an igniter that controls energization/cutoff of the primary coil current of the ignition coil based on the distributor rotation signal from the magnetic pickup caused by the rotation of the signal rotor in conjunction with the engine, the engine rotation during cranking and the engine rotation during cranking are controlled. an extremely low speed determination circuit that changes the output, and a threshold voltage when shaping the distributor rotation signal waveform of the igniter based on the output during cranking from the extremely low speed determination circuit, to a value equal to or lower than the maximum output voltage of the magnetic pickup during cranking; ρThe threshold voltage for shaping the distributor rotation signal waveform of the igniter is set to a voltage that changes in response to the power supply voltage when the ignition coil does not reach its heat generation limit using the non-cranking output from the extremely low speed determination circuit. and a power transistor drive circuit that controls energization and interruption of the primary coil current of the ignition coil based on the waveform shaping output of the distributor rotation signal of the igniter. Igniter for engine.
