Abstract

The present invention relates to an engine front cover with a rotational support insert. The engine front cover assembly includes a plastic engine cover. A metal insert is secured within the plastic engine cover and defines a bore configured to receive a rotating engine component. A seal is located in a seal seat defined within the bore of the metal insert and configured to sealingly engage the rotating engine component. The metal insert is overmolded within the plastic engine cover and serves as a datum point to properly locate the seal relative to the rotating engine component.

Description

technical field [0001] The present invention relates to an engine assembly and, more particularly, to a front and rear engine cowl made of plastic and having an insert molded metal insert defining an aperture for receiving rotating engine components. Background technique [0002] This section provides background information that is not necessarily prior art that is related to the present invention. [0003] Currently, engine covers (front or rear) are manufactured from aluminum castings or steel stampings. Aluminum castings offer flexibility in design, but the cost and mass of aluminum is considerable and it is desirable to use significantly lighter components. Contents of the invention [0004] The present invention relates to a front hood assembly including a plastic hood. Metal inserts are secured within the plastic hood and define apertures for receiving rotating engine components. A seal is located within a seal seat defined within the bore of the metal insert and ...
