Abstract
A fuel injector support assembly for mounting a fuel injector to the cylinder head of an engine. The fuel injector support assembly includes a fuel injector clamp attached to a bracket. The bracket is secured to the cylinder head by cylinder head mounting bolts, which are used also to fasten the cylinder head to the engine block. The fuel injector clamp is attached to the bracket and secures the fuel injector to the cylinder head.
Claims24
An engine, comprising:
- an engine block;
- a cylinder head;
- at least one cylinder head mounting bolt that fastens the cylinder head to the engine block;
- a bracket mounted to the cylinder head using the at least one cylinder head mounting bolt;
- and
- a fuel injector clamp attached to the bracket.
An engine comprising:
- an engine block;
- a cylinder head secured to the engine block;
- a fuel injector configured to be secured to the cylinder head;
- and
- means for both fastening the cylinder head to the engine block and fastening the fuel injector to the cylinder head.
A method of fastening a fuel injector to an engine, comprising:
- securing a cylinder head to a block of the engine using a plurality of cylinder head mounting bolts;
- mounting a fuel injector support assembly to the cylinder head using at least one of the plurality of cylinder head mounting bolts;
- and
- securing a fuel injector to the fuel injector support assembly.
An engine comprising:
- an engine block;
- a cylinder head secured to the engine block by a plurality of cylinder head mounting bolts;
- a bracket, having a recessed portion, mounted to the cylinder head using at least one of the plurality of cylinder head mounting bolts;
- a fuel injector clamp attached to the bracket using a threaded fastener that mates with a threaded bore located in the recessed portion of the bracket, wherein the fuel injector clamp has a forked arm that receives a fuel injector and a heel that contacts the bracket;
- and
- a fuel injector engaged by the forked arm of the fuel injector clamp and secured to the cylinder head by a downward force created upon tightening of the threaded fastener into the threaded bore.
A fuel injector support assembly, comprising:
- a bracket that mates with at least one mounting boss of a cylinder head of an engine;
- and
- a fuel injector clamp attached to the bracket and configured to securely engage a fuel injector.
The fuel injector support assembly 21, further including a fastener that secures the fuel injector clamp to the bracket, wherein the fastener is a threaded fastener that extends through the fuel injector clamp and into a threaded bore in the bracket.
The fuel injector support assembly 21, wherein the bracket and fuel injector clamp are formed together as an integral unit.
