Abstract
Air air-cooled multi-cylinder internal combustion engine with a cylinder row through which cooling air flows transversely to the cylinders. Two guide ribs are cast-on at the cooling air discharge side of each cylinder at a distance to one another which are constructed as thin-walled profiles and are angularly bent through about 90.degree. in mutually opposite directions.
