Title:

IGNITION DEVICE AND STRUCTURE FOR MOUNTING SAME

Document Type and Number:

WIPO Patent Application WO/2012/073564

Kind Code:

A1

Abstract:

An ignition device (100) comprises: a discharge power source (2); an AC power source (3); an ignition coil (41) for generating a secondary voltage in a secondary coil (41B); an ignition plug (1) connected to the secondary coil (41B); an AC electrode (43) electrically connected to the AC power source (3); a high-voltage electrode (42) positioned between the secondary coil (41B) and the ignition plug (1); an insulating body (44) positioned between the two electrodes (42), (43); a capacitor (49) formed by the two electrodes (42), (43) and the insulating body (44); and a second insulating body (47) covering the ignition coil (41). The secondary voltage and AC power are supplied to the ignition plug (1) via the high-voltage electrode (42). It is thereby possible to obtain an excellent ignition performance while minimizing the occurrence of flameouts.
