<P>PROBLEM TO BE SOLVED: To solve the problem of reducing output of an igniter under the influence of a leak current when a distance between respective diodes is near, or the problem of complicating and enlarging a structure when constituting arrangement of the diodes by taking into consideration the leak current of the respective diodes, when providing the diodes in both ignition coils for preventing voltage of one ignition coil from flowing in the other ignition coil, in an igniter for performing assist discharge. <P>SOLUTION: This high frequency igniter includes a backflow preventive diode for checking a backflow of a large electric current from the ignition coil on the secondary high voltage side of a high frequency ignition coil, and the ignition coil and the high frequency ignition coil are stored in one case, and an insulating mold resin is filled in a coil storage part in the case, and the diodes are provided in the case. The high frequency ignition coil rises a pulse of a high frequency switching element by detecting falling of a pulse of an ignition switching element, and the high frequency ignition coil starts an ignition signal after completing an ignition signal of the ignition coil. <P>COPYRIGHT: (C)2013,JPO&INPIT |
