ABSTRACT:
An electric motor is placed on an upstream side of an exhaust gas recirculation passage of a housing in a direction that is parallel to an intake air flow direction. A first heat release part on a motor housing part of the housing is placed on an upstream side of an exhaust suction aperture in a direction of an intake air flow. A heat release of the electric motor is promoted by direct contact between a new intake air with much lower temperature than an EGR gas and the first heat release part of the motor housing part. Therefore, on the upstream side of the exhaust suction aperture in the direction of the intake air flow, the electric motor can be cooled by the new intake air. By utilizing the intake air suctioned into an inlet port of an engine, the electric motor and the like can be efficiently cooled.
