摘要： A spark plug RFI suppression arrangement comprises a spark plug having a proximal end at which an ignition terminal is located and a distal end at which a pair of electrodes are separated by a spark gap. The spark plug further has an insulator portion and a conductive case located intermediate the proximal and distal ends. The arrangement further has an ignition wire having an end portion carrying a connector removably attached to the ignition terminal of the spark plug. A spark plug boot is located at the end portion of the ignition wire, the boot being configured to cover the connector and at least a portion of the spark plug. A radio frequency interference (RFI) suppression sleeve is connected to the spark plug boot and is in electrical communication with the conductive case of the spark plug such that interference produced by operation of the spark plug is suppressed by grounding through the conductive case.

摘要： A spark plug for an internal combustion engine includes a center electrode, an insulator holding the center electrode inserted therein, a housing holding the insulator inserted therein, a ground electrode joined to the housing so as to form a spark discharge gap with the center electrode, and a stem electrically connected to the center electrode. The stem includes a stem body inserted and held inside the insulator and a terminal exposed from a proximal end of the insulator. The insulator includes a supported portion axially supported by the housing. A heat insulating member is interposed between the stem and the center electrode. A conductive member is disposed inside the insulator so as to pass through the heat insulating member for making electrical connection between the stem and the center electrode. The heat insulating member is located closer to a proximal side of the insulator than the supported portion is.
