## Abstract

A fuel injector assembly for use with an engine block of a direct injection engine. The fuel injector assembly includes an elongated tubular fuel rail which is fluidly connected to a high pressure fuel source. At least two fuel cups are attached to and extend downwardly from the fuel rail and each fuel cup is adapted to receive one fuel injector. First fasteners attach a bracket to the engine block while second fasteners attach the bracket to the fuel rail. These second fasteners, furthermore, are positioned so that the second fasteners are coplanar with a plane extending through a longitudinal axis of each fuel injector.

## Claims

### Claim 1

A fuel injector assembly comprising:
an elongated tubular fuel rail adapted to be fluidly connected to a fuel source,
at least two fuel cups attached to and extending outwardly from said fuel rail, each fuel cup adapted to receive one of fuel injectors,
a bracket,
first fasteners for attaching said bracket to an engine block,
second fasteners for attaching said bracket to said fuel rail, said second fasteners positioned so that said second fasteners are configured to secure said fuel rail under said bracket through a longitudinal axis of each fuel injector in a bank of fuel injectors.

### Claim 2 (depends on 1)

The fuel injector assembly as defined in claim 1 wherein said second fastener is configured to secure said fuel rail so that a vibration dampener is sandwiched between said bracket and said fuel rail.

### Claim 3 (depends on 2)

The fuel injector assembly as defined in claim 2 wherein said dampener comprises an elastomeric material.

### Claim 4 (depends on 1)

The fuel injector assembly as defined in claim 1 wherein each said second fasteners comprise a pin attached to and extending outwardly from said fuel rail, said pin extending through an opening in said bracket, and a clip attached to said pin.

### Claim 5 (depends on 4)

The fuel injector assembly as defined in claim 4 wherein said clip is positioned on the side of said bracket opposite from said fuel rail.

### Claim 6 (depends on 4)

The fuel injector assembly as defined in claim 4 wherein an axis of said pin lies in said plane.

### Claim 7 (depends on 1)

The fuel injector assembly as defined in claim 1 wherein said second fasteners are positioned between said fuel cups.

### Claim 8 (depends on 1)

The fuel injector assembly as defined in claim 1 further comprising said fuel injectors.

### Claim 9 (depends on 2)

The fuel injector assembly as defined in claim 2 further comprising said fuel injectors.

### Claim 10 (depends on 4)

The fuel injector assembly as defined in claim 4 further comprising said fuel injectors.

### Claim 11

A vehicle comprising:
a fuel pump,
an engine block, and
a fuel injector assembly,
wherein said fuel injector assembly comprising:
an elongated tubular fuel rail adapted to be fluidly connected to said fuel pump,
at least two fuel cups attached to and extending outwardly from said fuel rail,
each fuel cup adapted to receive one of fuel injectors,
a bracket,
first fasteners for attaching said bracket to said engine block,
second fasteners for attaching said bracket to said fuel rail, said second fasteners positioned so that said second fasteners are configured to secure said fuel rail under said bracket through a longitudinal axis of each fuel injector in a bank of fuel injectors.

### Claim 12 (depends on 11)

The vehicle as defined in claim 11 wherein said second fastener is configured to secure said fuel rail so that a vibration dampener is sandwiched between said bracket and said fuel rail.

### Claim 13 (depends on 12)

The vehicle as defined in claim 12 wherein said dampener comprises an elastomeric material.

### Claim 14 (depends on 11)

The vehicle as defined in claim 11 wherein each said second fasteners comprise a pin attached to and extending outwardly from said fuel rail, said pin extending through an opening in said bracket, and a clip attached to said pin.

### Claim 15 (depends on 14)

The vehicle as defined in claim 14 wherein said clip is positioned on the side of said bracket opposite from said fuel rail.

### Claim 16 (depends on 14)

The vehicle as defined in claim 14 wherein an axis of said pin lies in said plane.

### Claim 17 (depends on 11)

The vehicle as defined in claim 11 wherein said second fasteners are positioned between said fuel cups.
