ABSTRACT:
Disclosed is an improvement in aircraft engines of the opposed piston type comprising cylinders arranged side by side. Cooling efficiency is improved and both average and hot zone temperatures are decreased by an improved air distributor comprising channel and divider members. The channel member is so proportioned and arranged as to admit air in an open mouth near the unfinned portions of adjacent cylinder barrels and to divert some of the barrel zone cooling air to the heads. The divider penetrates substantially into the zone between heads and is offset so that the larger portion of diverted air goes to the hotter head zone.
