Abstract

A fuel injector system comprising a universal fuel injector assembly having a universal electrical receptacle, and a family of specific adaptors for connecting the universal fuel injector assembly to a corresponding family of specific engine harnesses and/or design layouts. The universal fuel injector assembly has an injector tip and fuel rail tip compatible with the engine and fuel rail sockets of a plurality of engines. Each adaptor comprises a fuel-injector plug at a first end for mating with the electrical socket and a harness-specific plug or socket at a second end for mating with a specific harness socket or plug.

Claims

1. A fuel injector system for use with a plurality of internal combustion engines having differing wiring harnesses, comprising:

a) a universal fuel injector assembly having a universal electrical receptacle; and

b) a plurality of adaptors for connecting said universal fuel injector assembly to any one of a corresponding plurality of specific engine wiring harnesses.

2. A system in accordance with claim 1 wherein said universal fuel injector assembly includes an injector tip compatible with a plurality of injector sockets on said plurality of internal combustion engines.

3. A system in accordance with claim 1 wherein said universal fuel injector includes a fuel rail tip compatible with a plurality of fuel rail sockets on said plurality of internal combustion engines.

4. A system in accordance with claim 1 wherein each of said adaptors includes a first end for connection to said fuel injector universal electrical receptacle and a second end for connection to a one of said plurality of engine wiring harnesses.

5. A system in accordance with claim 4 wherein said first end includes a plug for mating with said fuel injector universal electrical receptacle, and wherein said second end includes a plug or socket for mating with said wiring harness.

6. A system in accordance with claim 5 further including a wiring cable electrically connected between said first end plug and said second end plug or socket.

7. An internal combustion engine comprising a fuel injector system for use with a plurality of internal combustion engines having differing wiring harnesses, said system including a universal fuel injector assembly having a universal electrical receptacle, and a plurality of adaptors for connecting said universal fuel injector s assembly to any one of a corresponding plurality of specific engine wiring harnesses.
