ABSTRACT:
An internal combustion engine shutdown device is disclosed. The device stops an engine running at high speed in a controlled fashion when a condition arises in a peripheral device or apparatus being driven or operated by the engine. The device provides a relay, a fuel shutoff control, an engine throttle control, and a timer. Upon the receipt of an external signal such as the de-energizing of a conventional "kill switch", the device immediately reduces engine speed to idle by the throttle control and delays the stopping of the engine by the timer until a pre-set time period has passed. Once the time period has elapsed so that the engine is in the proper state to be stopped, the fuel to the engine is cut off by the fuel shutoff control. The device is particularly adapted to the operation of an internal combustion engine used in a center pivot irrigation system.
