Abstract

A method for controlling a compression ignition electronic control module equipped compression ignition internal combustion engine installed in a vehicle to permit engine idling to conform to requirements of a geographical location.

Claims

1. A method for controlling an electronic control module equipped internal combustion engine idling to conform to requirements of a geographical location, comprising;

determining whether the engine is idling;

determining whether the engine is located within a geographical location that restrict engine idling;

determining whether the engine idle time is greater than or equal to the allowed engine idle time within the geographical location within which the engine is operating;

shutting down the engine when the engine idle time exceeds the allowed idle time within the geographical location within which the engine is operating.

2. The method of claim 1, further including the step of determining whether auxiliary devices mode require engine operation.

3. The method of claim 1, further including the step of overriding idle shutdown by depressing the accelerator pedal.

4. The method of claim 1, wherein the electronic control module is equipped with look up tables that contain data on engine idle operation permitted by any given geographical location.

5. The method of claim 1, wherein said geographical location of the engine is communicated to the electronic control module by wireless communication.

6. The method of claim 5, wherein said wireless communication is a global positioning satellite transmission signal.

7. The method of claim 1, wherein said geographical location of the engine is communicated to the electronic control module through an interface to the electronic control module.

8. The method of claim 1, wherein said power take off mode includes said auxiliary power mode.

9. The method of claim 1, further including monitoring the vehicle engine to determine whether the vehicle engine is idling.
