Abstract
An air-cooled multi-cylinder internal combustion engine includes cylinder heads cast together in a cylinder head casting; the cylinder heads are cooled from the inside by an S-shaped air flow extending between the valves. The cooling air thereby flows-in through an inlet channel at the inlet side of the cylinder heads, is deflected through 90.degree. in a central connecting channel and after a once-more 90.degree. deflection flows into the atmosphere through outlet channels which are formed between the individually cast exhaust gas outlet channels.
