摘要： An intake system for a multicylinder internal combustion engine includes a manifold having inlet runners for conducting charge air into the cylinders of an engine, and at least one secondary throttle valve situated within at least one of the inlet runners. An electrically driven motor positions the secondary throttle valve, with the motor being operated by a controller, which senses engine operating parameters including the temperature of an electrically driven motor which powers the secondary throttle valve.
