  • Ignition coil for an internal combustion engine
    Patent number: 6216679
    Abstract: An ignition coil for an internal combustion engine improves high-voltage sealing performance and moreover reduces housing outer diameter. The ignition coil for an internal combustion engine is made up of a transformer portion of cylindrical configuration housed within a housing chamber of a case, a control-circuit portion, that is positioned on one end portion of this transformer portion, causing primary current of the transformer portion to be intermittent, and a connecting portion that is positioned on another end portion of the transformer portion, supplying secondary voltage of the transformer portion to a spark plug. A silicone rubber injection molding serves as the encapsulant while forming the high voltage boot to the plug.
