Patent ID: 6857411

Claim:
Lubricating oil supply system for connecting rod bearings of a crankshaft of a multi-cylinder internal-combustion engine, in which oil ducts extend from bearing journals to crank pins of the crankshaft, oil supply taking place by way of main bearings of the crankshaft, wherein the oil ducts extend from one main bearing or bearing journal respectively to the crank dins or connecting rod bearings in each case adjoining on both sides, wherein, in respective bearing journals of the crankshaft, for lubricating oil supply to the connecting rod bearings adjoining on the left and right, respectively, two oil bores respectively are provided which extend at an angle and, converging to a third oil bore, extend to two adjoining crank pins, wherein the two oil bores interact with oil supply grooves provided in the main bearings for the lubricating oil supply, and wherein the crankshaft is provided for a 6-cylinder opposed-cylinder engine, in which the two crank pins arranged adjacent to the bearing journals are arranged to be mutually offset by a crank angle of 180°.
