  "textContent": "A controller for an internal combustion engine, a control method for an internal combustion engine, and a memory medium are provided. The controller determines whether an execution request of a temperature-increasing process for an aftertreatment device for exhaust gas has been issued. When the execution request is determined as having been issued, supply of fuel by a fuel injection valve corresponding to a specified cylinder is deactivated. The specified cylinder is one of cylinders. An air-fuel ratio of air-fuel mixture in a cylinder of the cylinders that differs from the specified cylinder is set to be richer than a stoichiometric air-fuel ratio. When the temperature-increasing process is executed, an adjustment device is operated so as to reduce the fuel concentration in an intake port connected to the specified cylinder.",
