Abstract: An ignition apparatus includes a spark plug and an ignition coil. The spark plug has a plug terminal protruding proximalward from an insulator. The ignition coil includes a coil main body, which includes a primary coil and a secondary coil, and a helical spring that electrically connects the secondary coil and the plug terminal. The plug terminal is made of a material that is both electrically conductive and magnetic. The plug terminal includes a terminal main body, which has an outer diameter greater than an inner diameter of the spring, and a terminal extension portion that has an outer diameter less than the inner diameter of the spring and extends proximalward from the terminal main body. A distal end portion of the spring abuts the terminal main body. The terminal extension portion is inserted and arranged in the spring. Between an outer circumferential surface of the terminal extension portion and an inner circumferential surface of the spring, there is interposed an insulating member.

Abstract: A break ignition plug for piston engines wherein an electromagnet acts upon an armature which activates a movable electrode and an ignition pulse passes through the magnet coil of the electromagnet and a short-circuit path between the electrodes. The magnetic field which builds-up in the electromagnet causes breaking of the short-circuit path and spark formation. At the free end of blade or band springs arranged in spaced relationship from one another at the lengthwise axis of the ignition plug there are provided confronting electrode heads. The blade springs are retained at the magnet core and freely protrude by means of the electrode ends into a hollow space or chamber formed at a threaded portion of the ignition plug. At a magnet gap region of the core there are formed at the blade springs armatures which repel one another upon excitation of the electromagnet.

Abstract: A spark plug having a superimposed magnetic field for use in internal combustion engines is disclosed. A magnetic field generator, such as a magnet, is disposed in proximity to the anode of the spark plug. The magnet produces a magnetic field which field alters the conductive properties of the envelope surrounding the anode and cathode electrodes. The resultant nonisotropic conductivity, in turn, promotes a larger arc envelope or plasma and hence a better probability of ignition of the combustible mixture within the engine.

Abstract: A contact-breaking ignition plug comprises a magnet coil arranged in a housing and surrounding a magnet core. The magnet core comprises an enlarged end portion with lateral surfaces extending conically in relation thereto and also comprises a cavity in which an armature is movably arranged. The armature is mounted on a rod in asymmetrical relation to a longitudinal center plane of the cavity and in transverse relation to the direction of compression pressure propagation. These features induce a concentration of the magnetic effect in the armature region and cause the contact-breaking motion to be augmented by the compression pressure. Respective contact electrodes are exchangeably mounted at each of the free end of the armature and a nose of the housing. The contact electrodes are mounted such that an electrical ignition pulse traversing a short-circuit path extending from the magnet coil of the electromagnet through the contact electrodes induces a magnetic field in the electromagnet, leading to interruption of the short-circuit path and the formation of a spark. The interruption sequence can be accelerated by means of this contact-breaking ignition plug and can be more precisely controlled and material deformations no longer arise during the contact-breaking motions.

Abstract: A wire cleaner having a chamber and containing an arc ring for passing a wire therethrough, such that when the wire and arc ring are provided with opposite electrical potentials, an electric arc discharge occurs from the wire to the arc ring which carries off impurities from the surface of the wire. An inert gas is used to purge the chamber to prevent oxidation of the wire during and following the discharge from the wire. A pair of annular permanent magnets are positioned around the wire on each side of the arc ring to produce a magnetic field parallel to the wire which interacts with the electrical arc discharge and causes the arc to rotate around the circumferences of the wire and arc ring, thereby cleaning the entire wire. A second embodiment is provided in which the pair of permanent annular magnets is replaced by a variable strength electromagnet surrounding the arc ring and wire path.

Abstract: An ignition device for a combustion chamber of an internal combustion engine includes a first electrode and a second electrode, which is movable with the aid of an actuator. The ignition device is configured to generate a first ignition spark when a contact between the first and second electrode is interrupted. To accomplish this, the second electrode is moved away from the first electrode. A third electrode is also provided, which is spaced apart from the first electrode. With the aid of the third electrode, a second ignition spark can be generated by moving the second electrode away from the other two electrodes. With the three electrodes, the ignition unit is configured to allow the two ignition sparks to pass through a volume formed between the electrodes in the direction transverse to the longitudinal extension of the ignition sparks in the course of the movement of the second electrode.
