Abstract
Engine-driven equipment includes a stopped-engine detector and a mechanism for safely shutting down the engine, including battery operated auxiliary devices, after detection that the engine has stopped. The engine may be shut down simply by closing a gas cock in the fuel line, but whatever the cause of engine stoppage, auxiliary devices are permitted to run for a predetermined time after stoppage to, for example, cool the engine or maintain warm glow plugs for easier restarting. If the gas cock is used to stop the engine, the engine will continue to run until fuel remaining in the fuel line has been expended, and then safely and automatically shut-down.
Claims13
Engine-driven equipment of the type including an engine, a generator driven by the engine, and a battery, and comprising:
- a generator output terminal to which said battery and said generator are connected via a switch;
- stopped-engine detection means for detecting that the engine has stopped and thereafter issuing a stopped-engine signal;
- and
- electric circuit opening means for opening at least said switch by means of the stopped-engine signal issued by said detection means.
Engine-driven equipment of the type including an engine and a battery, and comprising:
- stopped-engine detection means for detecting that the engine has stopped and thereafter issuing a stopped-engine signal;
- electric circuit opening means for opening electrical circuits by means of the stopped-engine signal issued by said detection means;
- main switch means for turning off said engine when thrown;
- and
- means for causing said engine to continue operating until fuel remaining in the fuel line has been expended after said main switch means has been thrown.
