Abstract
A device for stopping a diesel engine can properly control an engine stopping operation even if an engine rotation signal is not transmitted due to disconnection of a signal line at the time of the engine stopping operation and can prevent an engine stopping actuator from being burnt even if the engine does not stop due to mechanical trouble in a stopping mechanism. A contact 1a of a key switch 1 is turned from an ON terminal to an OFF terminal, whereby a transistor TR3 of a engine stopping operation section 8 us turned off. A transistor TR4 is turned on by a discharge of a capacitor C4, and a transistor TR5 and a relay switch 10 to follow are turned on to actuate a solenoid 11 to shut off fuel supply through a stopping mechanism. If a signal is not input into an engine rotation detection section 6, or, if the engine does not stop due to mechanical trouble in the stopping mechanism, the transistor TR4 is automatically turned off with expiration of a setting time defined by the capacitor C4, and the solenoid 11 returns to an initial state.
