ABSTRACT:
An engine shut-down control device comprises a shut-down controller for outputting an engine shut-down signal in dependency on a rotation signal generated by an engine rotation when a key switch is turned off and for maintaining self-hold operation until the rotation signal stops, and a start controller for non-electrifying a starter while the rotation signal is output regardless of the position of the key switch. When the key switch is turned off, the shut-down controller automatically holds the device by outputting the engine shut-down signal in dependency on the rotation signal generated from the engine rotation. Namely, the engine shut-down signal is output until the engine completely stops and output of the rotation signal is stopped.
