  • IGNITION COMPONENT
    Publication number: 20120312268
    Abstract: An ignition component 100 provided with a center electrode 30 and an insulator 32, in which the insulator 32 is formed of a large-diameter portion 33 and a small-diameter portion 34, the large-diameter portion 33 of the insulator 32 is inserted into the plug insertion hole 21 of the cylinder head 20 of the internal combustion engine, and a stepped portion 35 between the large-diameter portion 33 and the small-diameter portion 34 of the insulator 32 is pressed onto and fixed to the side of the cylinder head 20 of the internal combustion engine so that the insulator 32 is attached to the cylinder head 20 of the internal combustion engine is provided.

  • Ignition device of internal combustion engine and electrode structure of the ignition device
    Patent number: 8261711
    Abstract: An ignition device having an electrode structure including an anode, a cathode, an auxiliary electrode, an anode coating, an auxiliary electrode coating, and an anode supporting body. A coated surface of the anode is opposed to a coated surface of the auxiliary electrode with the anode coating, a combustion space, and the auxiliary electrode coating therebetween. An exposed surface of the anode is opposed to an exposed surface of the cathode with the combustion space therebetween. A distance D1 from the coated surface of the anode to the coated surface of the auxiliary electrode via the anode coating, the combustion space, and the auxiliary electrode coating is shorter than a distance D2 from the exposed surface of the anode to the exposed surface of the cathode via the combustion space (D1<D2). A combustion bomb may be used as the cathode.
