INTERNAL COMBUSTION ENGINE

A compressor that feeds intake air under pressure is attached to an intake passage of an internal combustion engine. An intercooler that cools intake air is attached to a portion of the intake passage on a downstream side of the compressor. One end of an exhaust gas recirculation passage that allows a part of exhaust air flowing in an exhaust passage to return is connected with the exhaust passage in the internal combustion engine. The other end of the exhaust gas recirculation passage is connected with a portion of the intake passage on an upstream side of the compressor. A dehumidifier that removes moisture contained in gas is attached to a portion of the intake passage from a connecting portion with the exhaust gas recirculation passage through the compressor.
