Patent number: 8704435Abstract: A spark plug has a cylindrical housing case, a cylindrical glass insulator, a center electrode, and an earth electrode fixed to the cylindrical housing case. The earth electrode has a projected part which is projected toward the center electrode. The projected part has a facing surface which faces the center electrode and is most close to the center electrode in a spark discharge gap. This gap is formed between the center electrode and the earth electrode. The facing surface is covered with a plating layer. A base material, with which the earth electrode is made, is exposed on a side surface of the projected part around the facing surface of the projected part. The base material of the earth electrode is made of Ni alloy containing not less than 90 wt % Ni, and preferably, Ni within a range of 90 wt % to 98 wt %.Type: GrantFiled: July 3, 2012Date of Patent: April 22, 2014Assignee: Denso CorporationInventors: Satoru Kadowaki, Toshikazu Shimizu

Patent number: 8456071Abstract: A spark plug for use in an internal combustion engine. The spark plug is equipped with a metal shell, a ground electrode joined to the metal shell, and a center electrode disposed in the metal shell. The ground electrode has a protrusion formed on a top end thereof. The metal shell and the ground electrode are covered with a plated layer which has a thickness of 2 ?m to 18 ?m, which minimizes the possibility of peeling of the plated layer from the ground electrode while keeping the plated layer as thin as possible without sacrificing the resistance to corrosion on the ground electrode.Type: GrantFiled: December 14, 2011Date of Patent: June 4, 2013Assignee: Denso CorporationInventor: Satoru Kadowaki

Patent number: 8398447Abstract: A method of manufacturing a spark plug having an attachment fitting 2, an insulator 3, a center electrode 4 and an earth electrode 5. While fixed to attachment fitting 2, earth electrode 5 has a convex part 510 formed by projecting a part of an opposed surface 51 toward center electrode 4, and a concave part 520 formed toward the opposed surface 51 from the earth electrode's back surface 52. The convex part 510 is disposed so that the extension of a shaft center of the convex part 510 passes through the area in which the concave part 520 is formed. The relation S1>=s is realized when an area of an opening of the concave part 520 is set to S1 and an average cross-section area of a cross section of the convex part 510 perpendicular to an axial direction of the spark plug is set to s.Type: GrantFiled: April 2, 2012Date of Patent: March 19, 2013Assignee: Denso CorporationInventors: Ken Hanashi, Satoru Kadowaki, Tsunenobu Hori, Kenka Tsubota, Hirotaka Aida, Hiroya Ishiguro

Patent number: 7723906Abstract: A spark plug for an internal combustion engine is provided which includes a metal shell, a porcelain insulator, a center electrode, and a ground electrode. The center electrode is retained in the porcelain insulator to define a spark gap between itself and the ground electrode. The porcelain insulator has a nose made up of an upright portion and a tapered portion continuing from the upright portion toward a top end thereof. The tapered portion has a diameter decreasing toward the top end of the porcelain insulator. The upright portion has an outer wall extending substantially parallel to an inner wall of the metal shell, thereby inducing the formation of side sparks between the tapered portion and the metal shell before the insulation resistance between the center electrode and the metal shell drops, thereby giving a signal indicative of such an event to an operator.Type: GrantFiled: December 6, 2007Date of Patent: May 25, 2010Assignee: Denso CorporationInventors: Satoru Kadowaki, Yasutake Ishino
