Abstract

A device for fastening an exhaust manifold to an internal combustion engine is provided. The device includes two parts. A first part that has first elongated holes for a screw fastening to the engine and openings for a screw fastening of a second bracket part. The second bracket part is fork-shaped, angular, and has on the angle branch facing the first bracket part second elongated holes and on the other angle branch, third elongated holes. The longitudinal axes of at least two of the elongated holes are oriented perpendicular to one another.

Claims

1. A device for fastening an exhaust manifold to an internal combustion engine, the device comprising:

a first bracket part having first elongated holes in a first portion thereof for screw fastening of said first bracket part to an engine block,

a second bracket part having a U-shaped portion on one end thereof having spaced apart legs, and an end of said second bracket part opposite from said U-shaped portion extending in a first plane which is disposed at an angle to a second plane within which said U-shaped portion extends, and said opposite end of said second bracket having second elongated holes, and said U-shaped portion having third elongated holes,

said first bracket part including a second portion having openings spaced from said first elongated holes for screw fastening of said second bracket part to said first bracket part, said second portion of said first bracket part extending in a different plane than said first portion of said first bracket part, said first portion of said first bracket and said second portion of said first bracket being connected by a third bracket portion extending in a plane offset from the planes in which said first and second portions extend such that said first bracket portion has a stepped configuration,

wherein longitudinal axes of at least two of the first, second or third elongated holes are oriented perpendicular to one another.

2. The device according to claim 1, wherein said openings in said first bracket part are threaded.

3. The device according to claim 1, wherein nuts are welded on behind the openings in said first bracket part.

4. The device according to claim 1, wherein said first and second planes of said second bracket part are perpendicular to each other.

5. The device according to claim 1, wherein a longitudinal axis of said second elongated holes and a longitudinal axis of said third elongated holes are perpendicular to each other.

6. The device according to claim 1, wherein said third elongated holes are located in each leg of said U-shaped portion of said second bracket part.

7. The device according to claim 1, wherein said openings of said first bracket part and said second elongated holes of said second bracket part are of such dimension and are so positioned on said respective first and second bracket parts to permit attachment of said first and second bracket parts together.
