Abstract

Official abstract text for this publication.

An internal combustion engine has an oil circuit for supplying oil to powertrain components and cylinder head components of the internal combustion engine. At least one oil pump and one oil filter module are incorporated into the oil circuit. The oil circuit branches into a powertrain oil gallery and a cylinder head oil gallery in the oil filter module or downstream of the oil filter module in a flow direction. The oil circuit is designed so that a lower oil pressure prevails in the powertrain oil gallery than in the cylinder head oil gallery.

First claim

Opening claim text (preview).

What is claimed is: 1. An internal combustion engine comprising: powertrain components that include crankshaft bearings and connecting rod bearings; cylinder head components that include hydraulic consumers, camshaft bearings and/or valve drive components; and an oil circuit for supplying oil to the powertrain components and the cylinder head components of the internal combustion engine, an oil pump and one oil filter module being incorporated into the oil circuit, the oil circuit including: an outlet bore extending down from the oil filter module, a powertrain oil gallery extending along a straight path from the outlet bore, and a cylinder head oil gallery branching laterally from the outlet bore at a branching point downstream of the oil filter module and upstream of both the powertrain oil gallery and the cylinder head oil gallery in a flow direction so that an oil flow from the outlet bore is divided at the branching point upstream of both the powertrain oil gallery and the cylinder head oil gallery into separate oil flows going respectively to the powertrain oil gallery and the cylinder head oil gallery, a diameter of the powertrain oil gallery being greater than a diameter of the cylinder head oil gallery at least in a sub-region downstream of the branching point, wherein the greater diameter of the powertrain oil gallery and the straight path of the powertrain oil gallery from the outlet bore ensures that a lower oil pressure and a higher volume flow of oil prevails in the powertrain oil gallery than in the cylinder head oil gallery that branches laterally from the outlet bore, and wherein a quotient of the diameter of the powertrain oil gallery and the diameter of the cylinder head oil gallery is between 1.2 and 2.0. 2. The internal combustion engine of claim 1 , wherein the oil circuit is part of a dry-sump lubrication arrangement. 3. The internal combustion engine of claim 1 , further comprising an oil cooler between the oil pump and the oil filter module.
