Abstract
To facilitate construction of internal combustion engines rotating in opposite directions using the same crankcase, three recessed bearings 5, 5a, 5b, are formed in the crankcase. For engines operating in a first direction of rotation, a first bearing 5 supports a first intermediate gear 4 to provide the driving connection between the crankshaft 2 and the camshaft 7, and for an engine having an opposite direction of rotation the second and third bearings 5a, 5b, support a second intermediate gear 4 and the first intermediate gear 8 to provide the driving connection between the crankshaft 2 and the camshaft 7. This construction permits a simple conversion operation to change the rotation direction of the internal combustion engine.
