Estimating the term…
An air-cooled, reciprocating piston, internal combustion engine has at least two adjacent cylinder barrels with a plurality of cooling ribs lying substantially perpendicular to the longitudinal axes of the barrels on at least part of the periphery thereof. The intake ports of the cylinder heads are located on the cooling air inlet side while the exhaust ports are located on the cooling air outlet side, and an air deflection cover overlies the cylinder barrels on the cooling air outlet side. The cylinder barrels are provided on the cooling air outlet side with cooling ribs lying substantially parallel to the longitudinal axes of the cylinder barrels. The air deflecting cover is of a configuration such that at least some of the cooling air flowing, in the area adjoining the crankcase, around and between adjacent cylinder barrels, is deflected toward these parallel lying ribs, so that essentially the total flow of cooling air supplied may be used to cool the hottest area of a cylinder barrels.
An air-cooled, reciprocating piston, internal combustion engine having a crankcase and at least two adjacent cylinder barrels on said crankcase, comprising a plurality of cooling ribs lying substantially perpendicular to the longitudinal axes of said cylinder barrels on at least a part of the periphery thereof, cylinder heads on said cylinder barrels, said heads and said barrels having a cooling air inlet side and a cooling air outlet side, said heads each having an intake port at said inlet side thereof and each having an exhaust port at said outlet side thereof, at least one air deflecting means mounted on said outlet side of said cylinder barrels, and said cylinder barrels having cooling ribs on said outlet side thereof lying substantially parallel to said longitudinal axes, said air deflecting means overlying said parallel lying cooling ribs whereby at least some cooling air which flows laterally around and between said adjacent cylinder barrels is capable of being deflected toward said parallel lying cooling ribs.
