Patent number: 11280275Abstract: An internal combustion engine includes an internal combustion engine body including an intake valve and an exhaust valve, and a controller configured or programmed to perform a control to set a rotational speed of the internal combustion engine body to a predetermined rotational speed based on an environmental temperature at a time of starting the internal combustion engine body, and perform a control to drive the internal combustion engine body at the set predetermined rotational speed during a time period until when fuel is supplied to a combustion chamber of the internal combustion engine body and first ignition is performed.Type: GrantFiled: July 10, 2019Date of Patent: March 22, 2022Assignee: AISIN CORPORATIONInventors: Seiichi Fujimoto, Tomohiro Kozaki, Masaaki Kaneko, Suguru Kamiya, Atsushi Hanaura, Tatsuki Okude, Tomoaki Fukao

Patent number: 11156170Abstract: A control device for an internal combustion engine includes an internal combustion engine and a valve opening-closing timing control device. The valve opening-closing timing control device has a phase adjustment mechanism for setting a relative rotation phase of a driving-side rotator and a driven-side rotator. The phase adjustment mechanism overlaps a timing of opening an intake valve with a timing of opening an exhaust valve, by setting, in a predetermined period, the relative rotation phase such that the exhaust valve closes after a top dead center position has been reached, and a bypass passage is provided that connects an exhaust passage of one cylinder that is in an exhaust process to the exhaust passage of another cylinder that is in an intake process at the same time as the exhaust process.Type: GrantFiled: February 28, 2018Date of Patent: October 26, 2021Assignee: AISIN SEIKI KABUSHIKI KAISHAInventors: Seiichi Fujimoto, Masaaki Kaneko, Hirokazu Tanaka, Suguru Kamiya, Kohei Fujii

Patent number: 10619588Abstract: A controller for an internal combustion engine includes: a failure determination section which determines a failure state in a case where a relative rotation phase of an intake side valve opening and closing timing control mechanism does not change when controlling the mechanism after starting the driving of a starter motor and trying to change the relative rotation phase of the mechanism in a start control for starting an internal combustion engine. When the section determines a failure, the controller performs at least one of an intake air amount increase control in which an opening degree of a throttle valve is increased, an ignition timing advance angle control in which injection of fuel is performed at a timing earlier than a set timing and ignition is performed, and a multi-injection control in which the fuel is injected immediately before the ignition in addition to the fuel injection in an intake stroke.Type: GrantFiled: July 12, 2018Date of Patent: April 14, 2020Assignee: AISIN SEIKI KABUSHIKI KAISHAInventors: Seiichi Fujimoto, Hirokazu Tanaka, Masaaki Kaneko, Tomohiro Kozaki, Suguru Kamiya, Atsushi Hanaura

Publication number: 20200072131Abstract: An internal combustion engine includes: an intake control valve provided on an upstream side of a fuel injection device provided in an intake flow path and configured to adjust an opening degree thereof while maintaining an intake state through the intake flow path; and a controller configured to perform control to adjust the opening degree of the intake control valve, in which the controller is configured to set the intake control valve to a closing direction side such that a pressure between the intake control valve and an intake valve of a combustion chamber increases during a pre-ignition motor drive period until a fuel is supplied to the combustion chamber and first ignited.Type: ApplicationFiled: August 28, 2019Publication date: March 5, 2020Applicant: AISIN SEIKI KABUSHIKI KAISHAInventors: Suguru KAMIYA, Seiichi FUJIMOTO, Masaaki KANEKO, Atsushi HANAURA
