Zusammenfassung:	Provided is an engine control device for a saddle-type vehicle with which responsiveness can be improved when accelerating from a state in which the engine speed has fallen below the engine speed at which a centrifugal clutch is disengaged. In this engine control device for a vehicle that is applied to a vehicle (1) equipped with a mechanical centrifugal clutch (C) that connects/disconnects driving force transmitted from an engine (E) to a drive wheel (WR), the vehicle (1) is equipped with: a throttle operator (47) for adjusting the engine (E) output; a motor (8) for causing a crankshaft (2) of the engine (E) to rotate; and a control unit (100) for controlling the motor (8) and a fuel injection device (52). The control unit (8) executes an injection stopping control for stopping the fuel injection when the vehicle (1) is decelerating, and executes an acceleration assist control for causing the crankshaft (2) to rotate by means of the motor (8) when an operation for opening the throttle operator (47) is performed after the engine speed has reached or fallen below a centrifugal clutch disengagement speed (Ne3) at which the centrifugal clutch (C) is disengaged.
