Abstract
There is provided a diesel engine shut-down device for stopping a diesel engine by actuating an engine shut-down mechanism with an actuator when an engine key switch is turned off. The device comprises a key switch detector for detecting the ON/OFF state of the key switch and for producing an engine stop signal when the key switch is in the OFF state, a rotation detector responsive both to the engine stop signal for detecting a rotation state of the engine so as to produce an actuator drive signal when the engine is rotating, an actuator driver responsive to the actuator drive signal for driving the actuator and a timer for stopping the production of the engine stop signal when a predetermined period of time elapses after the key switch is turned off, to stop the actuator after elapsing of the predetermind period of time even if the engine is not stopped though the actuator has operated.
