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: 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 being incorporated into the oil circuit, the oil circuit branching 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, and the oil circuit being configured so that a lower oil pressure prevails in the powertrain oil gallery than in the cylinder head oil gallery. 2 . The internal combustion engine of claim 1 , wherein an area of a branching point of the powertrain oil gallery and the cylinder head oil gallery is designed so that a lower oil pressure prevails in the powertrain oil gallery than in the cylinder head oil gallery. 3 . The internal combustion engine of claim 1 , wherein a diameter of the powertrain oil gallery is greater than a diameter of the cylinder head oil gallery at least in a sub-region downstream of the branching point. 4 . The internal combustion engine of claim 3 , 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. 5 . The internal combustion engine of claim 1 , wherein the powertrain components comprise at least crankshaft bearings and connecting rod bearings, whereas the cylinder head components comprise hydraulic consumers, camshaft bearings and/or valve drive components. 6 . The internal combustion engine of claim 1 , wherein the oil circuit is part of a dry-sump lubrication arrangement.
