Title:
IGNITION DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/156342
Kind Code:
A1
Abstract:
In this ignition device (1), a first switching unit (8) imparts a voltage between the electrodes of a spark plug (2) by means of turning on/off the electrification from a vehicle-mounted battery (17) to a primary coil (5A). Also, a second switching unit (10) imparts, in the same direction as that generated by means of the turning on/off of the first switching unit (8), a voltage between the electrodes of the spark plug (2) by introducing electrical energy stored at a voltage boosting circuit (9) to a primary coil (5B). As a result, it is possible for the complexity of turning on/off the first and second switching units (8, 10) to be reduced to a greater degree than has been conventional.
