  • Publication number: 20180331507
    Abstract: A spark ignition device includes a ceramic insulator with a metal shell surrounding at least a portion of the ceramic insulator. A ground electrode is attached to the shell. The ground electrode has a ground electrode sparking tip spaced from a central sparking tip by a spark gap. A first terminal is arranged in electrical communication with the central sparking tip and is configured for electrical connection with a power source. The device further includes a second terminal configured for electrical connection with the power source. The second terminal is spaced from the first terminal, with the second terminal being arranged in electrical communication with the first terminal. A heater element brings the first terminal in electrical communication with the second terminal and completes an electrical circuit. The heater element has a resistance greater than the first and second terminals thereby producing a significant source of heat.

  • Patent number: 9957948
    Abstract: An ignition unit produces an ignition in a combustion chamber of a combustion engine in the following manner. The ignition unit comprises a radiofrequency resonator that radiates a plasma-creating radiofrequency field into the combustion chamber. The ignition unit further comprises a microwave resonator that radiates a plasma-boosting microwave field into the combustion chamber. In an embodiment, the microwave resonator has an output surface to which the combustion chamber is exposed when the ignition unit is fitted on the combustion engine. The radiofrequency resonator may comprise an electrode that is at least partially embedded in the microwave resonator. The electrode may have a tip that is located at a distance from the output surface so that the microwave resonator provides a barrier between the tip and the output surface.

  • Patent number: 8026654
    Abstract: An ignition device for an internal combustion engine and method of construction therefore includes a housing with an insulator secured therein. A center electrode is mounted within the insulator. A ground electrode extends from the housing with a portion of the ground electrode defining a spark gap across from the center electrode. The center electrode has a firing tip, wherein a resistance weld joint initially bonds the firing tip to the center electrode and a continuous bead of overlapping first weld pools formed substantially from the material of the firing tip further bonds the firing tip to the electrode. A continuous bead of overlapping second weld pools formed radially outwardly from the first weld pools forms a rounded shoulder surface extending from the first weld pools to an outer surface of the center electrode.

The spark plug generally includes a shell, an insulator, and center and ground electrodes, with the electrodes each having a copper core for improved thermal conductivity and a noble metal insert for improved erosion and corrosion resistance. The noble metal insert for the center electrode is preferably in the form of a cylindrical Ir-based tip, which is received within a complimentary recess formed in the center electrode. The noble metal insert for the ground electrode is in the form of a flat Pt-based pad attached to a surface of the ground electrode. Various dimensional ranges are provided for the various components of the spark plug assembly, both individually and in combination with other dimensions.

  • Patent number: 7923909
    Abstract: An ignition device for an internal combustion engine and method of construction therefore includes a housing with an insulator secured therein. A center electrode is mounted within the insulator. A ground electrode extends from the housing with a portion of the ground electrode defining a spark gap across from the center electrode. At least a selected one of the center electrode or ground electrode has a platinum or platinum-based alloy firing tip. A resistance weld joint bonds the firing tip to the selected electrode and defines a lower surface of the firing tip that is embedded a first distance beneath an outer surface of the selected electrode. A continuous bead of overlapping laser weld pools is formed over an outer periphery of the firing tip. The overlapping weld pools extend a second distance beneath the outer surface of the selected electrode, with the second distance being greater than the first distance.
