  "textContent": "There is provided a control device for an internal combustion engine provided with a filter on the downstream side of a catalyst having an oxidation function, the device including: a control unit performing oxygen concentration reduction control for reducing the oxygen concentration of exhaust gas flowing into the catalyst based on an exhaust temperature increase request on the downstream side of the catalyst made when regeneration of the filter is performed, in which the control unit is provided with means for acquiring an S concentration value of a fuel combusted in the internal combustion engine, and in which the oxygen concentration is set based on the S concentration value. Accordingly, the white smoke resulting from combination between SO 3 and H 2 O can be suppressed while filter regeneration is performed.",
