Zusammenfassung:	An engine crankshaft includes a split crankshaft journal that includes offset connecting rod journals for two connecting rods. Oil supply systems disposed on opposite axial sides of the crankshaft journal each lubricate a corresponding one of the connecting rod journals. The oil supply systems are either axial or peripheral oil supply systems that do not require oil to be supplied to the crankshaft through the main crankcase bearings. Consequently, the oil supply systems sufficiently lubricate each connecting rod journal without requiring weakening holes or grooves in the main crankcase bearings.
