摘要： The disclosure illustrates an opposed multicylinder internal combustion engine suitable for aircraft use. The engine is fabricated from a pair of matched crankcase halves which enable die casting for limited production. The matched crankcase halves and rows of cylinder barrels and cylinder heads on opposed sides are secured by bolts which extend the width of the engine. The crankcase halves are mounted together at a series of ribs symmetrically positioned with respect to the midpoint of the crankcase halves. The cylinder barrels are mounted on pads offset from the midpoint so that the opposed barrels are in a staggered relationship on the assembled engine.
