Patent number: 11028747Abstract: A controller for an internal combustion engine includes a fuel introduction process of introducing an air-fuel mixture containing fuel injected by a fuel injection valve into an exhaust passage without burning the air-fuel mixture in a cylinder. The fuel introduction processor is configured to perform, during the execution of the fuel introduction process, a determination process of determining whether afterfire, in which the air-fuel mixture burns at an upstream side of a three-way catalyst device in the exhaust passage, has occurred and a stopping process of stopping the fuel introduction process when determining in the determination process that the afterfire has occurred.Type: GrantFiled: July 30, 2019Date of Patent: June 8, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yuki Nose, Yuto Ikeda, Hirofumi Hashinokuchi, Tatsuaki Suzuki, Eiji Ikuta, Yoshiyuki Shogenji, Hirokazu Ando

Patent number: 10774763Abstract: When stopping combustion in a cylinder under a situation in which the crankshaft of an internal combustion engine having an ignition device is rotating, a controller executes a fuel introduction process of injecting fuel from a fuel injection valve and introducing the fuel from inside the cylinder to the exhaust passage without burning the fuel. Also, the controller executes a storing process before starting the fuel introduction process. In the storing process, the controller stores oxygen in a three-way catalyst by executing a fuel cutoff process of stopping fuel injection of the fuel injection valve under a situation in which the crankshaft is rotating.Type: GrantFiled: July 2, 2019Date of Patent: September 15, 2020Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yuto Ikeda, Yuki Nose, Hirofumi Hashinokuchi, Tatsuaki Suzuki, Keiichi Myojo, Eiji Ikuta, Hirokazu Ando

Patent number: 10753298Abstract: A controller includes an air-fuel ratio control unit that calculates an air-fuel ratio F/B correction value and an air-fuel ratio learning value and corrects an amount of fuel supplied to each cylinder based on the air-fuel ratio F/B correction value FAF and the air-fuel ratio learning value KG. The controller further includes a dither control unit that executes dither control to adjust the amount of fuel supplied to each cylinder, corrected by the air-fuel ratio control unit, so that at least one of the cylinders is set to a rich combustion cylinder and at least a further one of the cylinders is set to a lean combustion cylinder. When the dither control is executed, the air-fuel ratio control unit prohibits execution of air-fuel ratio learning control and executes air-fuel ratio feedback control.Type: GrantFiled: August 6, 2018Date of Patent: August 25, 2020Assignee: Toyota Jidosha Kabushiki KaishaInventors: Tatsuaki Suzuki, Yuki Nose, Keiichi Myojo, Yoshiyuki Shogenji, Eiji Ikuta
