Patent number: 11459974Abstract: A vehicle includes an exhaust passage including an exhaust cleaner, an engine coupled to the exhaust passage, fuel injection valves, and a control device. The fuel injection valves are respectively provided in cylinders of the engine and inject fuel into the cylinders. The control device performs, after main-injection, post-injection control that causes the fuel injection valves to perform post-injection. The control device determines a fuel injection amount for single-time post-injection performed by each fuel injection valve such that the fuel injection amount for the single-time post-injection is greater than a fuel injection amount when the post-injection is performed in every combustion cycle in all the cylinders. The control device performs the post-injection control such that how many times the post-injection is performed is less than how many times the post-injection is performed in a case in which the post-injection is performed in every combustion cycle in all the cylinders.Type: GrantFiled: April 19, 2021Date of Patent: October 4, 2022Assignee: SUBARU CORPORATIONInventor: Ko Sato

Patent number: 10927775Abstract: An engine control device includes an air amount detector, a requested torque acquisitor, a search axis value acquisitor, a storage, and a control target value acquisitor. The air amount detector detects an actual amount of intake air. The requested torque acquisitor acquires a requested torque. In a region of a lean burn region where the actual amount of intake air increases as the requested torque increases, the search axis value acquisitor acquires a value corresponding to the actual amount of intake air. In a region of the of the lean burn region where the actual amount of intake air does not increase as the requested torque increases, the search axis value acquisitor acquires a value corresponding to the requested torque. The control target value acquisitor acquires a control target value of an engine device by searching a device control map using an acquired search axis value.Type: GrantFiled: May 29, 2019Date of Patent: February 23, 2021Assignee: SUBARU CORPORATIONInventors: Kazunari Wakimoto, Ko Sato
