An internal combustion engine includes a cylinder head, a cylinder block serving as an upper crankcase half for holding a crankshaft in at least two crankshaft bearings, at least one further shaft mounted in at least two shaft bearings, an oil circuit with oil-conducting lines for supplying oil to at least two bearings, and an exhaust-gas recirculation arrangement. A heat conductor runs between at least one of the bearings and a thermally more highly loaded region of the internal combustion engine which, at least in the warm-up phase of the internal combustion engine, is at a higher temperature than the associated bearing.
