  • Patent number: 11028748
    Abstract: In a dither control process performed on a fuel injection valve, at least one cylinder is set as a rich combustion cylinder and another cylinder is set as a lean combustion cylinder. A dither control process is executed in a first mode when a vehicle is driven in a normal manner by a user. The dither control process is executed in a second mode on condition that a command signal for performing a temperature raising process on the exhaust gas purifier is input from a device outside the vehicle at a repair shop. The absolute value of the difference between the air-fuel ratio of the lean combustion cylinder and the air-fuel ratio of the rich combustion cylinder obtained by the dither control process is set to be greater in the second mode than in the first mode.
