Abstract: An ignition system of electronic distribution type for an internal combustion engine with which merits of sharing circuits and elements can be expected with satisfactory result, in which wires of a GND line will not be disconnected by fusion even under a condition of abnormal power supply, and in which the engine will not be stalled even in a mode of simultaneously igniting two cylinders, thus enabling the limp-form traveling and made start-up with simultaneous ignition of two cylinders. To this end, power transistors 20 through 25 for power supply control and feedback control circuits 30 through 35 for limiting currents are respectively provided to control ignition coils 4 through 9 in one-to-one relation. A total of two systems of resistance devices 17a, 17b for detecting currents are provided with each resistance device operating a respective group of three cylinders. The feedback control circuits and the resistance devices for detecting currents are formed on a thick-film circuit board 60. Wires 50a, 50b used for connection between a GND portion on the thickfilm circuit board and an external GND terminal 50 are provided in the same number, i.e., two, as the number of resistance devices. The sequence of power distribution to the cylinders is determined, taking into account the fact that the resistance devices for detecting currents are each allocated to a respective group of three cylinders.

Abstract: An ignition system for an internal combustion engine comprising a semiconductor switching device, which is controlled by a control unit, is disclosed. In response to an output from a device for detecting a shorting breakdown or a heat generation of a power switching device, the power switching device and the ignition coil are cut off from a power supply by a current cut-off device. Even when the power switching device is broken by shorting, the power generation due to continuous energization of the ignition coil is prevented, thereby preventing the ignition coil from being heated abnormally.
