Abstract

An air-cooled internal combustion engine having a series of in-line cylinders with a cooling air blower adjacent an end cylinder. The blower delivers a stream of cooling air in the longitudinal direction of the engine which is redirected by air guide means laterally across the cylinders. To facilitate locating the blower nearer to the longitudinal central plane of the engine, several laterally spaced cooling fin parts are formed on the head structure of the end cylinder in alignment with the direction of flow of the stream of cooling air from the blower so that the overlapping relationship between the end cylinder head structure and the cross section of the blower does not adversely impede the air stream from the blower.
