PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine capable of removing deposit accumulated in a compressor.SOLUTION: A control device for an internal combustion engine includes: a supercharger having a compressor disposed in an intake path in the internal combustion engine and a turbine disposed in an exhaust path of the internal combustion engine; a low pressure gas circulation path connecting the exhaust path more downstream than the turbine to the intake path more upstream than the compressor; a low pressure EGR valve capable of opening and closing the low pressure exhaust gas circulation path; and an intake throttle valve capable of opening and closing the intake path more upstream than a connection part of the low pressure exhaust gas circulation path with the intake path. When the internal combustion engine is stopped, the intake throttle valve is fully closed, the low pressure EGR valve is fully opened. |
