ABSTRACT:
A deceleration control device of an engine comprising an intake passage which has a throttle valve therein. A bypass passage is branched from intake passage upstream of the throttle valve and is connected to the intake passage downstream of the throttle valve. A flow control valve is arranged in the bypass passage. At the time of deceleration, when the supply of fuel is cut, the flow control valve opens to increase the flow area of the bypass passage by a predetermined flow area.
