Abstract
The crankshaft of an engine is supported by bearing caps mounted on journal walls of a cylinder block and a bridge interconnects the bearing caps. Oil passages in each bearing cap lead from the bridge to each crankshaft journal bearing at a laterally offset location rather than on the cylinder axis. A longitudinal main gallery in the bridge supplies oil to the passages and is laterally offset even further to that side. A supply passage in the bridge and one bearing cap at one extreme lateral side supplies oil from a pressurized oil supply passage in the cylinder block to that supply passage in the bearing cap.
