摘要:
An object of the present invention is to provide a technique of improving the life of a spark plug which generates spark discharge and AC plasma. A plasma ignition device 20 includes a power control section 510 which reduces AC power P after generation of AC plasma in an AC power supply period Sa during which the AC power P is continuously supplied to a spark plug 100 within a maintainable power range Rp within which the AC plasma can be maintained.

The present disclosure relates to a mounting assembly (100) for mounting an ignition device (150) to a cylinder head (12) of an internal combustion engine. The internal combustion engine includes at least one combustion chamber (14). The mounting assembly (100) comprises a cylinder head cover (4) configured to be mounted to the cylinder head (12). The cylinder head cover (4) includes a bore (24) extending along a bore axis (26). The bore (24) is fluidly connected to the at least one combustion chamber (14) via the cylinder head (12). The mounting assembly (100) further comprises a mounting flange (2) mounted to the cylinder head cover (4). The mounting flange (2) is configured to seal the bore (24) and to mount the ignition device (150). In the mounting assembly (100) at least one of the cylinder head cover (4) and the mounting flange (2) includes a venting passage (52) configured to fluidly connect the bore (24) to the atmosphere.

Known ignition coils have a high-voltage connection, a spring for electrically connecting the high-voltage connection to a spark-plug and an elastic protective jacket that surrounds the spring. The windings of the spring lie in a block against one another in a block section that faces the high-voltage connection and are interspaced in a spring section designed to contact the spark-plug. To permit the ignition coil with the elastic protective jacket to be pushed easily onto the spark-plug, said protective jacket is reinforced by the integration of two metal sleeves. However, the disadvantage of these sleeves is that they involve higher production costs and increase the diameter of the protective jacket. In addition, the sleeves reduce the flexibility of the protective jacket. In the ignition coil according to the invention, the rigidity of the protective jacket is increased without additional components, thus cutting production costs and reducing the diameter of the protective jacket. According to the invention, the end of the block section (15.1) of the spring (15), facing the spring section (15.2), is supported on at least one support shoulder (20) of the protective jacket (16).

A plastic case (66) surrounds a primary winding (18) of a multicharge ignition system, and has a rib (68) in which the high voltage end is routed back to the low voltage end, so that the low and high voltage ends can be closely juxtaposed with each other while advantageously permitting the primary winding (18) to have one and only one winding layer to reduce resistance and size. The rib (68) of the case (66) extends into the slot (64) of the magnetic shields (62) of the winding.
