Patent number: 10344701Abstract: An engine system includes an engine that, a fuel supply device, and an electronic control unit. The electronic control unit is configured to control the fuel supply device and to perform operation control of the engine by adjusting an injection ratio between fuel injection from an in-cylinder injection valve and a port injection valve according to the operation state of the engine. The electronic control unit is configured to perform imbalance determination. The electronic control unit is configured to change a region of fuel injection from a first fuel injection region to a second fuel injection region when the electronic control unit determines that a lean imbalance is occurred with respect to the fuel injection in which the fuel injection from the port injection valve is performed.Type: GrantFiled: December 27, 2017Date of Patent: July 9, 2019Assignee: Toyota Jidosha Kabushiki KaishaInventors: Takeshi Genko, Daigo Ando, Chisa Watanabe, Shinya Kondo, Takahiro Nishigaki

Patent number: 10253684Abstract: An internal combustion engine control apparatus includes a secondary air supply device having a secondary air supply passage that supplies secondary air pumped by an air pump into an exhaust system of an internal combustion engine and an opening/closing unit that opens and closes the secondary air supply passage. A controller provided in the internal combustion engine control apparatus sets the opening/closing unit in an open condition such that the secondary air is supplied to the secondary air supply passage, and then executes foreign matter removal control in which the opening/closing unit is opened and closed. As a result, foreign matter caught in an ASV during AI control is removed immediately. By implementing OBD after removing the foreign matter, detection of an open sticking abnormality caused by foreign matter caught in the ASV is suppressed.Type: GrantFiled: August 6, 2012Date of Patent: April 9, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shinya Kondo, Ryosuke Tsukamoto, Hironori Kitadani, Jun Aoki, Shinsuke Kiyomiya, Kazuyoshi Tashiro, Satoshi Kawai, Tatsuro Nakata
