摘要： A spark-plug wire includes a boot of electrically insulative material defining a central bore configured to receive a spark plug, an electrical connector disposed in the central bore and configured to connect with the spark plug, and a cylindrical heat shield circumscribing the boot. The heat shield has retaining features extending past a distal end of the boot and configured to radially flex to engage with a hex of the spark plug to increase a retaining force of the spark-plug wire to the spark plug.

摘要： An apparatus for igniting a fuel mixture provides an ignition system for generating a high-voltage ignition voltage, a circuit device comprising a circuit for superimposing a high-frequency signal on to the high-voltage ignition voltage, a spark plug in an engine block, and a transmission element having a high-voltage conductor which is guided in an insulation element. The high-voltage conductor is used for transmitting the ignition voltage, onto which the high-frequency signal has been superimposed, to the spark plug. Further provided is an electrically conducting shielding element which surrounds the high-voltage conductor in an electromagnetically shielding manner at least along one portion of the longitudinal axis of the high-voltage conductor. The shielding element is connected in an electrically conducting manner to a ground potential of the circuit device and establishes a connection between the ground potential of the circuit device and a ground electrode of the spark plug.

摘要： An ignition coil for internal combustion engines is provided which includes a primary coil, a secondary coil, a case, a closing member, and a filled resin. The case includes a case body and a high-voltage tower. The closing member is press fit in the high -voltage tower to close the inside of the high-voltage tower. The closing member includes a resinous cylinder, a high-voltage terminal firmly attached to the resinous cylinder, and a resistor fit in the high-voltage terminal. The high-voltage terminal is of a hollow cylindrical shape with a bottom and an upper opening. The closing member has an outer peripheral surface of the resinous cylinder press-fit in the high-voltage tower. This structure minimizes pressure exerted on the resistor and the high-voltage tower to secure a desired degree of durability of the resistor and the high-voltage tower.

摘要： An improved general aviation igniter cable assembly includes either a single or double coil spring. The double coil spring has inner and outer portions. The outer portion has first and second ends. The first end rotatably engages the cylindrical recess in the ferrule. The outer portion surrounds the first end of the grommet with the second end bearing against the retainer. The distal end of the inner portion is located within the outer portion and bears against the first end of the grommet to put pressure on the spark plug contact button. For the magneto end of the cable, a sealing grommet fits slidably over an insulating sleeve of the cable and seals against a magneto plate when a surrounding threaded nut is tightened into a collar of the magneto plate and the plate is attached to a magneto, providing an airtight seal to the magneto plate and the magneto.
