Combustion engine and method for operating a combustion engine

The engine has inlet channels formed in a cylinder head (28) of an operating cylinder. A suction tube (34) for combustion air is connected with the inlet channels of the operating cylinder. A cooler (36) is arranged between the suction tube and the cylinder head such that the combustion air from the suction tube flows into the inlet channels through the cooler. The two inlet channels are designed as a filling channel (32) and a swirl duct (30). A partition is formed in the cooler that exhibits a cooling agent channel for a cooling agent that is selected from one of water, gas or oil. An independent claim is also included for a method for operating an internal-combustion engine.
