The invention relates to a control method and system for an internal combustion engine incorporating an engine shut-off valve, and in particular an air intake shut-off valve for a diesel or gas-fueled engine. The control system comprises a valve controller unit including a receiver capable of receiving sensor signals, and being in communication with the shut-off valve for permitting or preventing air flow in the shut-off valve upon receiving a triggering sensor signal.

1. A control system for an internal combustion engine having an air-intake shut-off valve, the system comprising a valve controller unit (VCU) including a receiver adapted to receive a sensor signal, a logic device capable of actuating the shut-off valve for permitting or preventing air flow to the engine, upon the VCU receiving a triggering sensor signal, and a data link for transmitting an outbound wireless signal from the VCU, wherein the VCU causes the data link to transmit the outbound wireless signal upon the VCU receiving the triggering sensor signal, andwherein the outbound wireless signal comprises either one or both of: another triggering sensor signal for another VCU associated with another internal combustion engine to actuate another air-intake shut-off valve associated with the another internal combustion engine; orelectronic data for audio or visual display of a message by a monitoring station or a mobile communication device that the engine is shut down. 2. The system of claim 1, wherein the internal combustion engine is a compression ignition or a spark ignition engine. 3. The system of claim 2, wherein the internal combustion engine is a compression ignition engine. 4. The system of claim 1, wherein the VCU is responsive to a wireless signal transmitted by a zone transmitter in a system comprising a worksite having two or more zone transmitters, each having a coverage zone within the worksite which is not coterminous with the coverage zone of any other zone transmitter. 5. The system of claim 1, further comprising an engine management computer or vehicle management computer interface operatively connected to the VCU. 6. The system of claim 1, further comprising a GPS receiver connected to the VCU. 7. The system of claim 1, further comprising an audio or visual recording device connected to the VCU. 8. A system for controlling at least one vehicle having a control system for an internal combustion engine having a shut-off valve in a worksite, divided into a plurality of zones, comprising a first zone transmitter associated with a first zone, and a second zone transmitter associated with a second zone, wherein the first zone transmitter does not reach the second zone, and the second zone transmitter does not reach the first zone, except for any overlapping areas, and wherein the control system of the at least one vehicle is responsive to signals from each zone transmitter to activate the air-intake shutoff valve. 9. A method of controlling at least one vehicle having a control system for an internal combustion engine having a shut-off valve in a worksite divided into a plurality of zones, comprising the steps of: (a) providing a plurality of zone transmitters, each associated with a zone, and each adapted to send a valve-shutoff signal to a control system within its zone; and(b) activating one or more zone transmitters for a selected zone or zones. 10. The system of claim 1, wherein the triggering sensor signal comprises a signal received from one or more of an engine sensor, a vehicle sensor, an environmental sensor, or an operator sensor. 11. The system of claim 10, wherein the triggering sensor signal is indicative of an operating condition of the engine or an ancillary component of the engine. 12. The system of claim 11, wherein the triggering sensor signal comprises a signal indicative of one or more of the following: revolutions per minute, running time, oil pressure, coolant temperature, engine vibration, battery voltage or charging conditions. 13. The system of claim 10, wherein the triggering sensor signal comprises a vehicle accelerometer signal. 14. The system of claim 10, wherein the sensor detects biometric properties of an operator. 15. The system of claim 10, wherein the sensor detects the intoxication level of an operator. 16. The system of claim 11, wherein the ancillary component is an actuator selected from a warning horn, a light, an interlock mechanism, or a pump controller. 17. The system of claim 11, wherein the ancillary component is a vehicle or engine control module capable of transmitting signals representative of operating conditions of the vehicle or engine to the VCU through a data bus. 18. The system of claim 1, further comprising a control panel connected to the VCU and having means for receiving a manual input for generating the triggering sensor signal. 19. The system of claim 18, wherein the control panel comprises display means providing visual or audible indicators for indicating whether the shut-off valve is open or closed. 20. The system of claim 1, further comprising a control panel is adapted to receive a voice command for generating the triggering sensor signal. 21. The system of claim 1, wherein the outbound wireless signal comprises the another triggering sensor signal for another VCU associated with another internal combustion engine to actuate another air-intake shut-off valve associated with the another internal combustion engine. 22. The system of claim 1, wherein the outbound wireless signal comprises the electronic data for an audio or visual message by a monitoring station or a mobile communication device that the engine is shut down. 23. A control system for an internal combustion engine having an air-intake shut-off valve, the system comprising a valve controller unit (VCU) including a receiver adapted to receive a sensor signal, and a logic device capable of actuating the shut-off valve for permitting or preventing air flow to the engine, upon the VCU receiving a triggering sensor signal, wherein the VCU is responsive to a wireless signal transmitted by a zone transmitter in a system comprising a worksite having two or more zone transmitters, each having a coverage zone within the worksite which is not coterminous with the coverage zone of any other zone transmitter.
