Abstract

A system includes an electronic fuel injection system of an engine, the electronic fuel injection system including an electronic governor control unit for controlling various functions of the engine.

Claims (28)

1. A system for tracking health of an air cleaner of an engine comprising:

an air manifold through which air passes in route to the engine;

an air cleaner through which air passes in route to the engine;

at least one sensor;

an electronic governor control unit in communication with the at least one sensor, wherein the electronic governor control unit is configured to receive at least one signal from the at least one sensor, to determine a threshold based on the at least one signal, and to average, record, and set over a first pre-determined number of hours of engine operation an average air flow;

an air pressure sensor configured to sense an air pressure in the manifold after the threshold has been determined and to generate a corresponding air pressure signal, wherein the electronic governor control unit is configured to receive the corresponding air pressure signal and to compare the corresponding air pressure signal to the threshold; and

wherein the electronic governor control unit is further configured to send a warning signal when the threshold has been exceeded.

2. The system of claim 1 , wherein the at least one sensor comprises the air pressure sensor.

3. The system of claim 1 further comprising a throttle, wherein the at least one sensor comprises a throttle position sensor configured to generate a throttle position signal based on a position of the throttle.

4. The system of claim 3 , wherein the at least one sensor further comprises the air pressure sensor.

5. The system of claim 1 , wherein the electronic governor control unit is configured to learn a baseline for the engine and the air cleaner based on the average air flow.

6. The system of claim 1 , wherein the electronic governor control unit is configured to determine the average air flow based on a correction factor.

7. The system of claim 1 , wherein the electronic governor control unit is configured to determine the average air flow based on an air flow calculation.

8. The system of claim 1 , wherein the electronic governor control unit is configured to determine the average air flow based on the corresponding air pressure signal.

9. A system for tracking health of an air cleaner of an engine comprising:

an air manifold through which air passes in route to the engine;

an air cleaner through which air passes in route to the engine;

at least one sensor;

an electronic governor control unit in communication with the at least one sensor, wherein the electronic governor control unit is configured to receive at least one signal from the at least one sensor, wherein the electronic governor control unit is configured to average, record, and set over a first pre-determined number of hours of engine operation an average air flow, and wherein the electronic governor control unit is configured to determine a threshold based on the at least one signal;

an air pressure sensor configured to sense an air pressure in the manifold after the threshold has been determined and to generate a corresponding air pressure signal, wherein the electronic governor control unit is configured to receive the corresponding air pressure signal and to compare the corresponding air pressure signal to the threshold; and

wherein the electronic governor control unit is further configured to send a warning signal when the threshold has been exceeded.

10. The system of claim 9 , wherein the at least one sensor comprises the air pressure sensor.

11. The system of claim 9 further comprising a throttle, wherein the at least one sensor comprises a throttle position sensor configured to generate a throttle position signal based on a position of the throttle.

12. The system of claim 11 , wherein the at least one sensor further comprises the air pressure sensor.

13. The system of claim 9 , wherein the electronic governor control unit is configured to learn a baseline for the engine and the air cleaner based on the average air flow.

14. The system of claim 9 , wherein the electronic governor control unit is configured to determine the average air flow based on a correction factor.

15. The system of claim 9 , wherein the electronic governor control unit is configured to determine the average air flow based on an air flow calculation.

16. The system of claim 9 , wherein the electronic governor control unit is configured to determine the average air flow based on the corresponding air pressure signal.
