HINGED ENGINE COVER FOR INTAKE MANIFOLD

摘要

An engine cover system for joining a cover with an intake manifold body. A plurality of structural ribs project from an external surface of the body including a pair of parallel ribs. Each parallel rib carries an integrally-molded U-shaped receiver strip extending transversely from the parallel ribs to form slots having closed ends proximate a first edge of the body and slot openings defined by respective edges of the receiver strips. The engine cover is comprised of a shroud, first and second radial arms, and first and second hinge pins projecting from the first and second radial arms, respectively. The hinge pins are configured to slide into the slots via the slot openings into the closed ends. First and second elastomeric ferrules are installed on the first and second hinge pins, respectively, configured to be compressed by the receiver strips when captured at the closed ends.

主权项

1. A combustion engine system comprising:
an intake manifold body comprised of molded polyamide defining a plurality of runners, an air intake passage, and parallel slotted ribs projecting from an external surface of the body oriented longitudinally and juxtaposed with a first edge of the body, wherein each slotted rib has a C-shaped slot with a mouth directed away from the first edge; an engine cover comprised of a shroud section adapted to cover the intake manifold body and a hinge section adapted to join with the slotted ribs, wherein the hinge section includes a spindle rotatably received by the slots; and elastomeric grommets disposed over the slotted ribs and within the slots adapted to compress within the mouth to capture the spindle within the slots, and wherein the spindle and cover are rotatable with respect to the slots.
