Title:
IGNITION DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2016/035639
Kind Code:
A1
Abstract:
An ignition device for an internal combustion engine, said ignition device being provided with: a spark plug (12); a first ignition coil (15A) and a second ignition coil (15B); a battery (11); a booster circuit (31) for boosting a voltage supplied from the battery; a power transistor (13) for allowing and interrupting passage of a primary current flowing into the primary coil (17A) of the first ignition coil; a MOSFET (25) for applying and disconnecting the voltage boosted by the booster circuit to the primary coil (17B) of the second ignition coil; and an ECU (20) that controls the power transistor so as to cause the spark plug to start electric discharge and causes the MOSFET to repeat application and disconnecting of the voltage boosted by the booster circuit such that the ongoing electric discharge is maintained.
