摘要

An air-cooled internal combustion engine has one cylinder (2), a ventilator housing (6) which partially surrounds the cylinder housing (12), wherein one blower wheel (7) which is driven, by a crankshaft (5), is arranged. Means is provided for deviating the semi-axial flow of the cooling flow (10) emerging from the blower wheel. An independent claim is also included for four stroke internal combustion engine with two intake valves.
