Abstract

A fuel delivery device for a fuel delivery system incorporates an electronic compensation device that either incorporates information that is relevant to the specific fuel delivery device or includes a processor that generates an actuator control signal that is based at least in part upon the information contained in the memory device.

Claims

1. A fuel delivery device comprising:

a fuel delivery device body;

an actuator mounted on said fuel delivery device body; and

an electronic compensation device mounted on said fuel delivery device body.

2. The fuel delivery device of claim 1, wherein the electronic compensation device comprises a processor in communication with the actuator, wherein the processor is responsive to a fuel delivery command to generate an actuator control signal.

3. The fuel delivery device of claim 1, wherein the electronic compensation device is an electronic memory device that includes information related to the fuel delivery device.

4. The fuel delivery device of claim 3, wherein the information includes test data regarding the fuel delivery device.

5. The fuel delivery device of claim 4, wherein the test data includes information regarding one of control curves, actuator delays, drain flow, injector cup flow and control orifice flow.

6. The fuel delivery device of claim 3, wherein the information includes manufacturing data.

7. The fuel delivery device of claim 6, wherein the manufacturing data includes information regarding one of orifice sizes, spring installed heights and spring load.

8. The fuel delivery device of claim 1, further comprising a sensor.

9. The fuel delivery device of claim 8, wherein the sensor comprises one of an injector temperature sensor, a fuel temperature sensor, a lift sensor, a start of injection sensor, an end of injection sensor, a fuel pressure sensor and a counter.

10. A fuel delivery system comprising:

an electronic control module; and

a fuel delivery device including;

a fuel delivery device body;

an actuator mounted on said fuel delivery device body; and

an electronic compensation device mounted on said delivery device body.

11. The fuel delivery system of claim 10, wherein the electronic compensation device comprises an electronic memory device that includes information related to the fuel delivery device.

12. The fuel delivery system of claim 10, wherein the fuel delivery device further includes a processor in communication with the actuator and the electronic control module, wherein the processor is responsive to a fuel delivery command from the electronic control module to generate an actuator control signal.

13. The fuel delivery system of claim 11, wherein the information includes test data regarding the fuel delivery device.

14. The fuel delivery system of claim 13, wherein the test data includes information regarding one of control curves, actuator delays, drain flow, injector cup flow and control orifice flow.

15. The fuel delivery system of claim 11, wherein the information includes manufacturing data.

16. The fuel delivery system of claim 15, wherein the manufacturing data includes information regarding one of orifice sizes, spring installed heights and spring load.

17. The fuel delivery system of claim 10, wherein the fluid delivery device further includes a sensor.

18. The fuel delivery system of claim 17, wherein the sensor comprises one of an injector temperature sensor, a fuel temperature sensor, a lift sensor, a start of injection sensor, an end of injection sensor, a fuel pressure sensor and a counter.
