ABSTRACT:
A crankcase for multi-cylinder reciprocable piston internal combustion engines of the single row type, in which a lubricant feeding bore extending in the longitudinal direction of the crankcase is arranged in the vicinity of the camshaft bearings and communicates through connecting bores with the crankshaft bearings. These connecting bores extend outside the connecting screws for the bearing covers through abutment surfaces by means of which the crankshaft bearing covers engage the crankcase, and lead into transverse bores in the crankshaft bearing covers. The above mentioned connecting bores intersect bores through which the connecting screws for connecting the bearing covers pass and eventually lead into the crankshaft bearings.
