摘要

The air feed system has a first system branch (3a) for delivering fresh air to the individual cylinders of the engine and a second system branch (3b) for feeding used air to the individual cylinders of the engine. The channel lengths (L1,L2) of the first system branch and the channel lengths (L1,L2) of the second system branch correspond to each other.
