摘要： To provide a spark plug that can reduce power loss and prevent erosion of a tip end part of a central electrode, even in a configuration such that a discharge current and an electromagnetic wave are emitted from a terminal fitting part of the spark plug, and a plasma generation device using the spark plug. The spark plug is provided with a central electrode 2 including a terminal fitting part 2A and an electrode main body 2B electrically connected to the terminal fitting part 2A, an insulator 3 formed with an axial hole 30, which the central electrode 2 is fitted into, a main fitting 4 that surrounds the insulator 3, and a ground electrode 5 that extends from an end surface of the main fitting 4 and is adapted to form a discharge gap that causes a spark discharge between the central electrode 2 and the electrode main body 2B. The electrode main body 2B is constituted of a front electrode 25 including an electrode tip part 25a for causing the spark discharge with the ground electrode 5, a front dielectric cylinder 24 in a tube-like shape that covers the electrode tip part 25a, and a coupling conductive cylinder 23 in a tube-like shape that joins the front dielectric cylinder 24 and the terminal fitting part 2A.

摘要： A spark ignition device, metal shell, and methods of construction are provided. The spark ignition device has a ceramic insulator extending along a longitudinal axis and a metal shell. The metal shell extends along the longitudinal axis to a distal end. A center electrode is received in the ceramic insulator and extends along the longitudinal axis. A ground electrode has an attachment end fixed by a weld joint to the distal end of the shell and a free end extending from the distal end to provide a spark gap. The weld joint includes a resistance weld joint and a laser weld joint, which in combination inhibit material expulsion; provide a reliable, strong attachment of the ground electrode to the shell; provide an improved heat transfer path between the ground electrode and the shell, and facilitate repeatable and accurate positioning of the ground electrode to the shell.

摘要： A spark plug and method of manufacturing the same. The spark plug includes a tubular insulator holding a center electrode, and a tubular metallic shell holding the insulator. The insulator is inserted into the metallic shell from the rear end side thereof until a portion of the insulator engages the metallic shell. In this state, the circumferential edge of the rear end portion of the metallic shell is crimped, whereby the insulator is unitarily fixed to the metallic shell. A talc charged layer is formed in a clearance portion between the insulator and the metallic shell, and a wire packing is placed on a rear end portion of the talc charged layer for engaging the crimp portion. A portion of the talc charged layer is interposed between the wire packing and the rear trunk portion of the insulator.

摘要： An engine spark ignition device for internal combustion engines having electrical coupling of the firing spark plug wire to the non-firing spark plug wires. The device is for use with an engine having a plurality of spark plug wires connected between a distributor and a spark plug disposed in the engine cylinder and comprises identical elongated electrically conductive semi-circular plates which enclose identical elongated electrically conductive planar plates having apertures therein that intersect to form spaces for receiving the spark plug wires. The interaction between firing spark plug wires and non-firing spark plug wires results in more efficient and cleaner combustion in the combustion chambers.
