    摘要: A spark plug fabricating method and a spark plug fabricated by the same are provided. The spark plug is equipped with a piezoelectric sensor working to measure the pressure of combustion of fuel in an engine and required to apply a given preload to the piezoelectric sensor at all the time. The piezoelectric sensor is disposed within a holder and retained between the holder and a porcelain insulator. The fabrication method includes the steps of pressing the holder to apply a required preload to the piezoelectric sensor in a longitudinal direction of the porcelain insulator and joining the holder to a metal shell while maintaining the preload applied to the piezoelectric sensor as it is.

    摘要: A sparkplug having multiple side discharge negative electrodes and employing an integral capacitor extending from the plug body to the area of the connector to the ignition system to effectively store the electrical energy normally lost during the rise time of the ignition transformer, and to discharge the stored energy across the electrode gap. The body (2) has a cylindrical extension which serves as the negative plate (10) of the capacitive element. A positive electrode (8) forms the interior portion of the sparkplug. One end of the positive electrode forms a spark gap (9) with two or more negative electrodes (7). The other end of the positive electrode (8) connects by means of a resistive connector (4) to a conventional high-voltage ignition cable. The positive electrode (8) serves as the positive plate of the capacitive element. A moldable dielectric material (11) completely fills the space between the positive and negative plates (8, 10) of the capacitive element for the length of the sparkplug, and also serves as the outer insulator of the spark plug.
