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.
Un système d'arrêt de moteur actionné à distance comprend un moteur ayant une admission d'air et une valve d'arrêt normalement ouverte aménagée sur l'admission d'air du moteur. La valve d'arrêt interrompt l'écoulement d'air dans le dispositif d'admission d'air lorsqu'elle est placée à la position fermée. Un actionneur permet de déplacer la valve d'arrêt de la position ouverte à la position fermée. Un émetteur portatif conçu pour envoyer un signal d'arrêt et un récepteur conçu pour recevoir le signal d'arrêt de l'émetteur sont également fournis. Un relais est installé entre le récepteur et l'actionneur de sorte que l'actionneur déplace la valve d'arrêt à la position fermée lorsqu'un signal est reçu par le récepteur.
