Patent number: 11165226Abstract: A spark plug is provided, including a housing, an insulator situated within a housing, the insulator having a longitudinal axis, an insulator foot, body, head, and seat. Inside the housing is a housing seat which is in contact with the insulator seat of the insulator. An inner seal is situated between the housing seat and the insulator seat, so that the inner seal, the housing seat, and the insulator seat form a sealing system. The insulator seat includes a step that has a first section and a second section having an angle ? to one another that is greater than 0° and the first section being parallel to the insulator longitudinal axis. The inner seal is in contact with this first section, so that a radial sealing surface is formed at the insulator.Type: GrantFiled: April 11, 2018Date of Patent: November 2, 2021Assignee: Robert Bosch GmbHInventors: Matthias Herzberg, Chris Schimmel

Patent number: 10886705Abstract: A spark plug is described as including an insulator which is situated in a spark plug housing and which has a longitudinal axis and an opening along the longitudinal axis. Furthermore, a center electrode is situated in the opening of the insulator. Furthermore, at least one ground electrode is provided at the spark plug housing. The insulator has a first insulator section and a second insulator section, the first insulator section extending in the direction of the longitudinal axis over a first insulator section length having a first inner diameter. The second insulator section extends in the direction of the longitudinal axis over a second insulator section length having a second inner diameter. Here, the first inner diameter is smaller than the second inner diameter, the first insulator section merging directly into the second insulator section.Type: GrantFiled: October 4, 2017Date of Patent: January 5, 2021Assignee: Robert Bosch GmbHInventors: Ugur Yilmaz, Chris Schimmel, Helene Kasjanow, Hermann Kersting

Patent number: 9979161Abstract: A spark plug with an improved heat-dissipating capacity of the center electrode. The spark plug includes a ground electrode, a center electrode and a ceramic insulator, which is designed to accommodate the center electrode. The center electrode has a center-electrode head which lies in the direction of an electrical connection region of the spark plug and which includes an end face that is in contact with an electrically conductive connection element disposed between the electrical connection region and the center-electrode head. At its outer periphery, the center-electrode head is at least regionally in heat-conducting contact with the ceramic insulator and forms a heat-conducting contact region.Type: GrantFiled: September 16, 2015Date of Patent: May 22, 2018Assignee: ROBERT BOSCH GMBHInventors: Chris Schimmel, Nicolai Claus
