Abstract

A charge air duct for an internal combustion engine includes a housing with at least one entrance and at least one exit for charge air. A heat exchanger is arranged inside the housing to cool the charge air, a bypass is arranged on the housing to at least partially circumvent the heat exchanger and an actuator is arranged on the housing to influence the charge air flow. The charge air is guided from the entrance to the heat exchanger in a first position of the actuator and from the entrance to the bypass in a second position of the actuator, and the actuator at least partially reduces a cross-section of the charge air in a third position.
