Abstract
A manifold anti-rotation system for engines includes a manifold having an end for interfacing with a manifold interface portion of an engine cylinder head, and a mounting collar. The manifold includes a protrusion extending from a periphery of the manifold end. The mounting collar comprises a collar body having a central aperture defined by an aperture wall wherein the aperture receives the manifold end therein. The mounting collar further includes a projection extending from a top surface thereof. The manifold protrusion and the collar projection are positioned to abut one another to prevent the manifold from rotating with respect to the mounting collar beyond the manifold protrusion.
Claims19
A manifold anti-rotation system for engines having an engine cylinder head with a manifold interface portion, said anti-rotation system comprising:
- a manifold having an end for interfacing with a manifold interface portion of an engine cylinder head, said manifold end having a protrusion extending from a periphery thereof;
- and
- a mounting collar further comprising a collar body having a central aperture therethrough defined by an aperture wall, said aperture receiving said manifold end therein, said mounting collar further including a projection extending from a top surface opposite from the cylinder head, said manifold protrusion and said collar projection cooperating to prevent said manifold from rotating with respect to said mounting collar beyond said manifold protrusion.
A mounting collar for mounting a manifold to a cylinder head of an engine, said mounting collar comprising:
- a collar body having a central aperture therethrough defined by an aperture wall for receiving an end of a manifold, and defining at least one aperture therethrough for receiving a fastener, and further including at least one collar projection extending upwardly from a top surface for cooperating with a corresponding protrusion extending outwardly from a manifold mounted by said mounting collar;
- and
- a seal retained by said collar body, said seal for abutting the manifold and the cylinder head.
A manifold anti-rotation system for engines having an intake portion of a cylinder head, said anti-rotation system comprising:
- an intake manifold having an end for interfacing with the intake portion of the engine cylinder head, said intake manifold end having a protrusion extending from a periphery thereof;
- and
- a mounting collar comprising a collar body and a seal, said collar body having a central aperture defined by an aperture wall, said central aperture receiving said manifold end therein and further including a projection extending from a top surface opposite from the cylinder head, said manifold protrusion and said mounting collar projection positioned to abut one to the other to prevent said intake manifold from rotating with respect to said mounting collar beyond said manifold protrusion, and further wherein said seal contacts said manifold and the intake portion of the cylinder head, said seal being retained by said collar body.
