摘要： A spark plug has an insulator having a through hole formed along an axial direction, a center electrode which is partially inserted into a portion of the through hole on a forward end side in the axial direction, and a glass seal portion which is in contact with the insulator and the center electrode within the through hole, in which the glass seal portion contains glass and an electrically conductive substance. The glass contains an Si component and a B component in a total amount of 50 mass % or more, as reduced to SiO2 and B2O3, a Zn component in an amount of 20 mass % to 35 mass % as reduced to ZnO, and an alkali metal component. The glass contains, as the alkali metal component, an Na component in an amount less than 1 mass % as reduced to Na2O.

摘要： Disclosed is a spark plug capable of suppressing high-frequency noise by improving the material of an electrical connection part between a center electrode and a metal terminal within an axial hole of an insulator. A spark plug has an electrical connection part arranged in an axial hole of an insulator to establish electrical connection between a center electrode and a metal terminal. The electrical connection part includes a conductor having a first crystal phase formed of a Fe-containing oxide and a second crystal phase formed of a conductive metal oxide of perovskite crystal structure.

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.
