Patent number: 11754032Abstract: An ignition system has an ignition plug and an ignition control unit that controls the ignition plug. When an engine is in a predetermined operating state, the ignition control unit performs ignition control after top dead center to perform ignition after the compression top dead center. The ignition system has an airflow support structure that facilitates the flow of airflow through a discharge gap at least after the compression top dead center. The ignition system is configured such that due to the airflow support structure and the timing of the ignition, airflow at a flow rate of 5 m/s or more flows through the discharge gap during a spark period after top dead center, which is the generation period of the discharge spark in the ignition control after top dead center.Type: GrantFiled: July 27, 2022Date of Patent: September 12, 2023Assignee: DENSO CORPORATIONInventors: Yasuomi Imanaka, Ryo Tamura, Yuji Kaji, Atsushi Iwami, Tatsuya Oka, Yuuta Kawashima
