たことを特徴とする直接分配型点火装置。 In an ignition system for a multi-cylinder internal combustion engine, the high voltage generated from the secondary winding of the ignition coil is directly distributed to the spark plugs of each cylinder by means of a high tension cord. In the high voltage wiring circuit for applying high voltage to the spark plug connected between the winding start terminal and the winding end terminal of the next winding, a spark discharge is generated for the high voltage that generates the ignition spark in the spark plug. arises,
A direct distribution type ignition device characterized in that discharge gap portions are connected in series and are spaced apart so that no spark discharge occurs in response to high voltage generated when the primary winding of an ignition coil is energized.
