Air-cooled internal combustion engine with a crankshaft which rotates about a vertical axis, especially a single cylinder diesel motor

摘要

An air cooled internal combustion engine with a crankshaft that rotates about a vertical axis is provided. The engine may be a single cylinder diesel motor. The internal combustion engine includes an encapsulation which surrounds a plurality of cooling air channels. A flywheel is positioned at the top end of the crankshaft and is combined with a radial blower. An air distribution housing, which is joined to a top front wall of the crank case, forms a pressure chamber of the radial blower. At least two substreams of cooling air branch off from the pressure chamber. A first substream is guided through the housing encapsulation, which surrounds the cylinder and the cylinder head. A second substream is guided in a lining on the outside of the sidewall of the crankcase and the oil pan facing the cylinder. Both substreams are collected on the downstream side and exit through a common air-extractor shaft.
