Abstract
An internal combustion engine includes a filter configured to capture PM contained in exhaust gas flowing through an exhaust passage. A CPU of a control device executes a calculation process of calculating a PM deposition amount, namely an amount of PM captured in a filter, based on an operating condition of the internal combustion engine and an alcohol content rate of fuel that is supplied into a cylinder, and when the PM deposition amount exceeds a specified amount, executes a regeneration process of burning PM captured in the filter.
