Control device for internal combustion engine

A control device for an internal combustion engine including a filter configured to trap particulate matter in an exhaust pipe connected to an engine body, the control device comprising:

• a condensed water remaining determination unit configured to determine whether condensed water remains in the filter, the condensed water remaining determination unit including a condensed water disappearance determination unit configured to
• acquire, from an exhaust temperature sensor provided on a downstream side of the filter, a temperature of exhaust gas that has passed through the filter, and
• determine that the condensed water remains in the filter in a state where the acquired temperature is lower than a preset threshold corresponding to a vaporization temperature of water;
• and
• a power suppression control unit configured to, in response to a determination that the condensed water remaining determination unit determines that the condensed water remains in the filter, limit an opening degree of a throttle valve to suppress power of the engine body as compared with a case where the condensed water does not remain in the filter.
