  • Integrated coil supporting unit slidably holding ignition coil units
    Patent number: 6885271
    Abstract: An interesting coil supporting unit for an engine includes an elongated casing and a plurality of coil units. Each coil unit has a coil support portion and an ignition coil. The coil support portions are disposed inside the casing at predetermined intervals. The casing and the respective coil support portions are fastened to a cylinder block by means of a plurality of bolts. In this state, each coil unit is supported by the corresponding bolt so as to be slidable in its radial direction. Therefore, the coil units can be positionally slid in the casing and thereby installed easily on the engine.

  • Ignition coil for internal combustion engine
    Patent number: 6747540
    Abstract: A conductive member is disposed between a secondary spool and a high tension terminal to shield the wire connecting the secondary coil and the high tension terminal. The conductive member has a wide surface facing the low tension components to moderate the electric field strength around low tension components, thereby preventing treeings from growing in the insulating filler of the ignition coil.
