摘要： In a spark plug in use for an internal combustion engine, a ground electrode is secured to a front end of the metal shell so that a front end surface of the ground electrode faces an elevational side of a front end of the center electrode to cause semi-creeping spark discharges therebetween along a front end surface of the insulator. A front end portion of the center electrode has an electrode base in the axial bore and an electrode front defined diametrically smaller than the electrode base by way of a diameter-variable portion. A diametrical difference between an initial point of the diameter-variable portion of the center electrode and the axial bore of the insulator is 1 mm or less, and the initial point of the diameter-variable portion is retracted by 0.0 mm-1.0 mm from the front end surface of the insulator.

摘要： An igniter plug comprising: a metallic shell having a diameter-reduced seat at one open end, the seat being tapered to progressively decrease its diameter as approaching at outside of the open end; a tubular insulator concentrically placed at an inner side of the metallic shell, and having a tapered end face to be in registration with the seat; a frusto-cone shaped insert ring made of oxidation and heat resistant material, a peripheral end and one entire surface of which are mounted on a surface of the seat by means of an electrical resistant welding, the insert ring permitting the tapered end face of the insulator to engage with an upper surface of the insert ring; a center electrode concentrically disposed in the insulator, one end of the electrode being terminated short of the tapered end face to allow a creeping discharge to occur along an inner surface of the insulator when a high voltage is applied across the electrode and the insert ring.

摘要： A spark plug for an internal combustion engine, the spark plug comprising a casing, a center electrode, a connector pin for the center electrode, and a plunger adapted to be axially displaced within the spark plug by the compression pressure as pressure builds in the cylinder, the plunger first closes a set of contacts in the spark plug causing current to flow in the primary side of an ignition coil, then closes a second set of contacts in the spark plug connecting the center electrode to the secondary side of the ignition coil, and finally opens the first set of contacts causing a large voltage to be induced in the secondary side which voltage is applied to the center electrode.

摘要： A surface-discharge igniter having concentric electrodes includes a gap at its operative tip which separates one of the electrodes from the exposed semiconductive surface of a semiconductive pellet that is interposed concentrically with the two electrodes. The said one electrode, which may be either the inner or outer electrode, is connected electrically to the pellet at the bottom of the gap away from the operative tip, whereas the other electrode makes contact with the pellet at, and in the region of, the exposed surface but is otherwise insulated electrically from it. Where the gap separates the inner electrode from the semiconductive surface then the outer electrode may be flared inwardly to establish its electrical connection with that surface. On the other hand, where the gap separates the outer electrode from the semiconductive surface the inner electrode may be flared outwardly, or provided with a cap that extends outwardly across the surface, to establish the connection with it. Holes for draining the gap may be provided through the outer electrode, and the pellet, which may be of material including silicon-carbide particles, may be brazed to the electrodes.
