SPARK DEVELOPING APPARATUS FOR INTERNAL COMBUSTION ENGINES |
摘要 |
Apparatus for developing and applying sparks to a combustion chamber of an internal combustion engine. The apparatus comprises separate primary (12) and secondary (10) winding units. The secondary unit includes a spark plug having an insulator (14). The insulator carries a secondary winding (30) which is connected to the electrodes (16,20) of the spark plug. The insulator has a bore (26) which contains a magnetic core (40) for the secondary winding. The primary winding unit includes a primary winding (52) and a tubular flux carrying part (58) formed of magnetic material. The primary winding unit has a bore which is slipped over a portion of the secondary unit that has the secondary winding. A voltage is induced in the secondary winding by magnetic coupling to the primary winding when it is energized. |
