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 first heat exchanger arranged inside the housing to cool the charge air, a bypass arranged on the housing to at least partially circumvent the heat exchanger, and an actuator arranged on the housing to influence the charge air flow. The charge air is guided from the entrance to the first 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 bypass leads upstream of a second heat exchanger of the charge air duct.
