An engine assembly for a motor vehicle, the assembly comprising a bearing housing portion configured to support a bearing for a crankshaft of the engine assembly, wherein the bearing housing portion comprises a bearing interface surface configured to interface with the bearing and an end face adjacent to the bearing interface surface, the end face being arranged so as to face a web of the crankshaft when installed;
- wherein the engine assembly further comprises a thermal insulation layer provided on the end face, the thermal insulation layer being positioned between the end face of the bearing housing portion and the web of the crankshaft when the crankshaft is installed in the engine assembly.
A method of insulating an engine assembly, the assembly comprising:
- a bearing housing portion configured to support a bearing for a crankshaft of the engine assembly, wherein the bearing housing portion comprises a bearing interface surface, configured to interface with the bearing, and an end face adjacent to the bearing interface surface, the end face being arranged so as to face a web of the crankshaft when installed, wherein the method comprises:
- providing a thermal insulation layer on the end face, such that the thermal insulation layer is positioned between the end face of the bearing housing portion and the web of the crankshaft when the crankshaft is installed in the engine assembly.
An engine assembly for a motor vehicle, the assembly comprising:
- a bearing housing contacting a bearing for a crankshaft along a bearing interface surface,
- an end face of the bearing housing extending away from bearing interface surface in a radial direction of the crankshaft and positioned to face a web of the crankshaft;
- and
- a thermal insulation layer on the end face positioned between the end face and the web of the crankshaft.
