Abstract: The invention relates to a control system for an internal combustion engine incorporating an engine shut-off valve for permitting or preventing air flow to an engine, and in particular a diesel or gas-fueled engine. The control system comprises a valve controller unit including a receiver capable of receiving incoming signals from a plurality of sources, and processing a received incoming signal to generate an output signal to output a shutdown command for actuating the shut-off valve for preventing air flow to the engine, and recording, in a memory, event data including a source identifier of the received incoming signal resulting in output of the shutdown command signal.

Abstract: A method and system of periodically cycling an air shutoff valve, upon a pre-determined length of time elapsing since the last valve cycle; or upon the cumulative run time of an engine since the last valve cycle exceeding a pre-determined value.

Abstract: 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.

Abstract: A method and system for reducing the risk of a moving machine colliding with an object involves a receiving antenna attached to the machine receiving an RF signal transmitted by a transmitting antenna attached to the object and energized by a power source. A processor operatively connected to the receiving antenna carries out a computer-implemented process under the direction of a set of program instructions stored in the memory component to determine the machine-object distance based on the strength of the RF signal at the receiving antenna. If the machine-object distance is less than a specified minimum safe distance, then the processor takes a preventative action such as actuating a sensory alarm, actuating a means for slowing the machine, or actuating an acoustic location device to more accurately determine the machine-object distance. The processor may also take a preventative action based on a state variable encoded in the RF signal.

Abstract: The invention is directed to a shut-off valve for stopping the air-flow to an engine. A butterfly valve disposed in an air passage is moved between a first open position and second closed position in a controlled fashion to prevent the build up un-burnt fuel in the event of the activation of the valve.
