Electronic fuel injection system and method for engines

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

a throttle;

a throttle position sensor configured to determine a position of the throttle, wherein the throttle position sensor is configured to generate a throttle position signal based on the position of the throttle;

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

an air pressure sensor configured to sense an air pressure in the manifold, wherein the air pressure sensor is configured to generate an air pressure signal based on the air pressure in the manifold;

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

an electronic governor control unit in communication with the throttle position sensor and the air pressure sensor, wherein the electronic governor control unit is configured to receive the throttle position signal and the air pressure signal, and wherein the electronic governor control unit is configured to determine a threshold based on the throttle position signal and the air pressure signal;

wherein the air pressure sensor is configured to sense air pressure in the manifold after the threshold has been determined and is configured to generate a second air pressure signal, and wherein the electronic governor control unit is configured to receive the second air pressure signal and is configured to compare the second 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 , where the threshold is determined for a high RPM and a high load pressure averaged and recorded over ten hours.

3. The system of claim 1 , where the electronic governor control unit is further configured to control a remote start of the engine.

4. The system of claim 1 , where the electronic governor control unit is further configured to control a speed limit of the engine.

5. The system of claim 1 , where the electronic governor control unit is further configured to control a closed loop trigger of the engine.

6. The system of claim 1 , where the electronic governor control unit is further configured to control engine power.

7. The system of claim 1 , where the electronic governor control unit comprises a microprocessor.

8. The system of claim 1 , where the electronic governor control unit is configured to track at least one of a number of starts, throttle position history, engine RPM history, oil temperature history, air temperature history, fuel used history, and voltage history.

9. The system of claim 1 , wherein the electronic governor control unit is configured to determine a plurality of thresholds.

10. The system of claim 9 , wherein the electronic governor control unit is configured to determine the plurality of thresholds based on various positions of the throttle, and wherein the electronic governor control unit is configured to store the plurality of thresholds in memory.

11. The system of claim 10 , wherein the air pressure sensor is configured to sense air pressure in the manifold after the plurality of thresholds are determined and stored in the memory and is configured to generate a plurality of air pressure signals, wherein the electronic governor control unit is configured to receive the plurality of air pressure signals and is configured to compare the plurality of air pressure signals to the plurality of thresholds.

12. The system of claim 11 , wherein each of the plurality of air pressure signals corresponds to one of the various positions of the throttle, wherein the electronic governor control unit is configured to compare each of the plurality of air pressure signals to a corresponding one of the plurality of thresholds based on the corresponding position of the throttle, and wherein the electronic governor control unit is configured to send a warning signal when one of the plurality of air pressure signals exceeds the corresponding threshold.
