摘要:
The bearing system for an automotive engine includes a first bearing support structure formed in a cylinder block bulkhead and having a first bearing insert. A second bearing support structure is removably mounted to the first bearing support structure and contains a second bearing insert. A lubrication channel formed in an inside diameter of the first bearing insert and an inside diameter of the second bearing insert extends along a portion of the first bearing insert from a smaller bearing clearance position offset from a first bearing parting line and into a smaller bearing clearance portion of the second bearing insert extending past a second bearing parting line. The lubrication channel provides an improved flow of oil to a drilled passage formed in a shaft, such as a crankshaft, to feed oil to various bearings, such as connecting rod bearings, while reducing oil leakage from such a bearing system.
