Patent number: 10415533Abstract: 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. When the path length has become too short, the ECU determines that ignition is expected to be delayed and then selects a special mode to control the delay of the ignition. 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: GrantFiled: May 12, 2016Date of Patent: September 17, 2019Assignees: DENSO CORPORATION, SOKEN, INC.Inventors: Hideaki Kosuge, Fumiaki Aoki, Shohei Ishida, Shunichi Takeda, Kazuaki Ueda

Patent number: 10138861Abstract: In an ignition device, a second circuit energizes a primary coil from its negative side in a first direction to thereby maintain energization of a second coil in a second direction during spark discharge started by a first circuit. The maintained energization continuously supplies energy to a spark plug, thus performing a continuation of the spark discharge. The first direction is opposite to a direction of energization of the primary coil carried out by the first circuit, and the second direction is the same as a direction of energization of the second coil that has been started based on the first circuit. A humidity detection unit detects humidity of intake air into an engine. The control section controls the first circuit to advance start timing of the spark discharge generated by the first circuit in accordance with an increase in the humidity of the intake air.Type: GrantFiled: July 26, 2016Date of Patent: November 27, 2018Assignees: SOKEN, INC., DENSO CORPORATIONInventors: Shohei Ishida, Shunichi Takeda
