Claim 4:
5. The controller for the internal combustion engine according to claim 1, wherein
the processing circuitry is configured to execute a front-end temperature estimating process and a rear-end temperature estimating process,
the front-end temperature estimating process is a process of estimating a front-side temperature, the front-side temperature being a temperature of a section of the exhaust purification device between a center and a front end,
the rear-end temperature estimating process is a process of estimating a rear-side temperature, the rear-side temperature being a temperature of a section of the exhaust purification device between the center and a rear end, and
the processing circuitry is configured to start the determination process on condition that the front-end temperature is higher than or equal to the rear-end temperature.
