Title:
IGNITION CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2014/168248
Kind Code:
A1
Abstract:
A control unit (319) in this ignition control device (30) controls switching elements such that stored energy is released from a capacitor (317) (due to a second switching element (314) being turned on) during an ignition discharge (which is started by a first switching element (313) being turned off), thereby supplying primary current to one end of a primary winding (311a), the other end thereof being connected to a DC power supply (312). In particular, the control unit controls the second switching element or a third switching element such that the amount of stored energy released from the capacitor can be varied in accordance with the operating state of an internal combustion engine.
