  • Internal combustion engine
    Patent number: 11280275
    Abstract: 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: Grant
    Filed: July 10, 2019
    Date of Patent: March 22, 2022
    Assignee: AISIN CORPORATION
    Inventors: Seiichi Fujimoto, Tomohiro Kozaki, Masaaki Kaneko, Suguru Kamiya, Atsushi Hanaura, Tatsuki Okude, Tomoaki Fukao
  • Valve opening and closing timing control apparatus
    Patent number: 11181050
    Abstract: A driving-side rotating body that rotates synchronously with a crankshaft of an internal combustion engine, a driven-side rotating body that is allowed to rotate relative to the driven-side rotating body and that rotates integrally with a camshaft that opens and closes an intake valve, and a phase adjustment mechanism for setting a relative rotation phase of the driving-side rotating body and the driven-side rotating body using a driving force of an electric motor are included. The phase adjustment mechanism is configured to be able to execute retarding control for setting the relative rotation phase to the retarding side until reaching a phase in which the internal combustion engine cannot be started and autonomous running is not possible even if fuel injection and ignition are performed in the internal combustion engine.
