Beveled dampening element for a fuel injector |
摘要 |
A direct fuel injection cylinder for an engine of a vehicle includes a direct fuel injector disposed in an injector bore within a cylinder head. A beveled conical wave washer is disposed between a shelf in the injector bore and a shoulder of the direct fuel injector. During operation of the vehicle, the beveled conical wave washer is elastically deformed by radial displacement caused by absorption of high frequency energy from the direct fuel injector. Elastic deformation of the beveled conical wave washer may reduce noise which may be caused by impact of the direct fuel injector and the cylinder head. |
