ABSTRACT:
The present invention relates to a cooling means for the squish part of an air cooling over head valve engine, comprising a fan disposed in front of said engine for generating cooling wind. A fan case is provided which covers the front side of the fan and engine. A wind tunnel is formed through the cylinder head of said engine near the squish area and is aligned so as to pass a cooling wind, generated by the fan, above the squish area. The engine is provided with an intake and exhaust ports opening at the front and rear surfaces of said cylinder head, respectively. In the lateral side of the wind tunnel, an intake or exhaust pipe is disposed laterally over the front space of the tunnel, so as to guide cooling wind blown up from the fan to the tunnel along its lower peripheral surface thereof.
