Abstract
A remotely activated engine shutdown includes an engine having an air intake and a normally open shutdown valve on the air intake of the engine. The shutdown valve blocks the flow of air through the air intake when placed in the closed position. An actuator is provided for moving the shutdown valve from the open to the closed position. A portable transmitter is provided which is adapted to send a shutdown signal. A receiver is provided which is adapted to receive the shutdown signal from the transmitter. A relay is provided from the receiver to the actuator, such that the actuator moves the shutdown valve to the closed position upon a signal being received by the receiver.
Description
TITLE OF THE INVENTION:
Remotely Activated Engine Shutdown FIELD OF THE INVENTION
The present invention relates to an engine shutdown which can be remotely activated.
BACKGROUND OF THE INVENTION
It is essential that all engines working in environments which may periodically experience a release of explosive gases have positive air engine shutdowns. An example of such an environment is a natural gas well. When explosive gases reach an air intake of an engine, the engine begins to race uncontrollably. An explosion can occur within the racing if the explosive gas mixes with oxygen and ignites. One form of engine shutdown presently in use, blocks the air intake to the engine. With the air intake to the engine blocked, no further explosive gases or air can enter the engine and the engine immediately stalls. The engine shutdowns generally have a shutdown switch mounted adjacent the engine. When the engine is in a vehicle, the shutdown switch is usually located in the cab of the vehicle. In order to activate the switch, workers must run toward the engine. In view of the danger of imminent explosion, it would be preferable if the workers could remotely activate the engine shutdown while running to safety away from the engine.
SUNMARY OF THE INVENTION
What is required is an engine shutdown which can be remotely activated.
According to the present invention there is provided a remotely activated engine shutdown which includes an engine having an air intake and a normally open shutdown valve on the air intake of the engine. The shutdown valve blocks the flow of air through the air intake when placed in the closed position. An actuator is provided for moving the shutdown valve from the open to the closed position. A portable transmitter is provided which is adapted to send a shutdown signal. A receiver is provided which is adapted to receive the shutdown signal from the transmitter. A relay is provided from the receiver to the actuator, such that the actuator moves the shutdown valve to the closed position upon a signal being received by the receiver.
With the remote engine shutdown, as described above, a worker in charge of an engine can remotely send a shutdown signal using the transmitter while running to safety.
In endeavouring to find a cost effective manner to place the present invention into effect, it was determined that a remote car starter could be modified to permit remote engine shutdown. A receiver unit of the remote car starter is connected to the actuator. A portable transmitter unit of the remote car starter can then send a shutdown signal.

DETAILED DESCRIPTION OF THE PREFERRED ENIDODIMENT
The preferred embodiment, a remotely activated engine shutdown generally identified by reference numeral 10, will now be described with reference to FIG. 1.
Structure and Relationship of Parts:
Referring to FIG. 1, an engine 12 has an air intake 14.
Air intake 14 is adapted with a shutdown valve 16. Shutdown valve 16 is, in turn, adapted with an actuator 18. A
receiver 20, adapted to receive wireless signals, is electrically connected to a relay 22. Relay 22 electrically connects to a power source 24 and then to actuator 18.
Portable transmitter 26 transmits wireless signals to receiver 20.
Operation:
The use and operation of remotely activated engine shutdown generally identified by reference number 10 will now be described with reference to the FIG. 1. Where remote engine shutdown is selected by an operator, a wireless signal is transmitted from portable transmitter 26 to receiver 20.
Receiver 20 signals relay 22 to provide power from the power source 24 to actuator 18. Actuator 18 causes shutdown valve 16 to close, cutting of the supply of air through air intake 14, effectively shutting down engine 12. With the remote engine shutdown, as described above, a worker in charge of an engine can remotely send a shutdown signal using the portable transmitter 26 while running to safety in the opposite direction.
In endeavouring to find a cost effective manner to place the present invention into effect, it was determined that a remote car starter could be modified to permit remote engine shutdown. In building an initial prototype, receiver 20 was a modified receiver unit from a remote car starter and portable transmitter 26 was a portable transmitter unit from the remote car starter.
In this patent document, the word "comprising" is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article "a" does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.
It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as hereinafter defined in the Claims.
