内燃機関用点火装置
Document Type and Number:
Japanese Patent JP3607902
Kind Code:
B2
Abstract:
An ignition device for an internal combustion engine includes a control circuit that generates an ignition signal for allowing or interrupting the supply of a primary current of an ignition coil under control, a waveform shaping circuit that waveform-shapes the ignition signal, a switching element that allows and interrupts the supply of the primary current on the basis of the ignition signal that is waveform-shaped to generate a high voltage on a secondary side of the ignition coil, and an over-current protection circuit that forcedly interrupts the supply of the primary current and holds an interrupt state until the ignition signal turns off when the primary current of the ignition coil exceeds a given value.
