Disclosed is an ignition drive module with stable performance and reliable function, which comprises a module signal input end, a voltage input end, a module signal output end, a comparator. One end of the comparator is connected to the module signal input end, and the other end is connected to a comparison resistance R that is grounded. The ignition drive module further comprises a maximum dwell timer module connected to the comparator, a logical judgment module connected to the comparator, and an IGBT module connected to the logical judgment module which receives the signals from the maximum dwell timer module and the comparator to determine whether to activate the IGBT module. The output end of the IGBT module is connected to the module signal output end.

A method for operating an ignition device for an internal combustion engine, in which via a rotating magnetic pole wheel a voltage signal with a number of positive and negative half-waves is produced in at least one coil arrangement that is located on a core leg of an iron core during each rotation of the magnetic pole wheel, wherein the voltage signal is used to determine the gap width of the air gap between the magnetic pole wheel and the core leg.

An ignition transformer includes a primary winding and a secondary winding and are electromagnetically coupled to each other. A battery is connected to a first end of the primary winding. A switch connected to a second end of the primary winding is turned on or off in response to an ignition signal. A saturable reactor includes a saturable core and includes a first winding, and a second winding the first and second windings electromagnetically coupled to each other. A first end of the first winding is connected to a first end of the second winding. A second end of the first winding is connected to the ignition plug. A reset circuit applies a reset voltage to the first and second ends of the second winding. The reset voltage is a voltage to switch a magnetization status of the saturable core between a saturated state and an unsaturated state.
