Publication number: 20180266381Abstract: An ignition apparatus for internal combustion engines is provided. The ignition apparatus is equipped with an ECU. The ECU monitors a path length of a discharge of a spark for a period of time in which a second circuit delivers or inputs energy in the form of a threshold value determination.

The ECU increase a target value of an energy input amount. This enables the delay of ignition resulting from a short extension of the path length to be minimized. The ignition apparatus equipped with the second circuit to continue the discharge of sparks is, thus, capable of reducing a variation in ignition without the need for uniformly increasing the energy input amount.Type: ApplicationFiled: May 12, 2016Publication date: September 20, 2018Inventors: Hideaki KOSUGE, Fumiaki AOKI, Shohei ISHIDA, Shunichi TAKEDA, Kazuaki UEDA

Publication number: 20180266407Abstract: An arrangement has a housing, which has a receptacle or an opening, and a cylindrical insert, which is mounted in the receptacle or opening via at least one interference fit. The insert has a peripheral groove, and therefore the insert is both fastened against the housing and sealed against the housing in a liquid- and/or gas-tight manner by way of material of the insert and/or housing that has been pressed into the groove during the assembly. The material of the insert and/or of the housing is displaced in the case of an interference fit. The groove provides a defined location to which the material can preferably flow. After the assembly has been concluded, the insert is locked against the housing by the material located in the groove. At the same time, the material acts as a seal between the insert and the housing. A separate seal in the region of the press fit becomes dispensable.Type: ApplicationFiled: December 9, 2015Publication date: September 20, 2018Inventor: Gilles HEBRARD
