PURPOSE:To improve the performance of acceleration upon reacceleration, by providing an electronic control device which opens a solenoid valve for closing a low speed fuel supply system upon deceleration, for carrying out reacceleration when the vehicle speed is lower than a predetermined speed. CONSTITUTION:A signal indicating an open degree of a throttle valve 2 and a signal indicating a vehicle speed are calculated in an electrinic control device 20 and actuate, when they reach predetermined values, a solenid valve 12 for shutting off low speed fuel. That is, a valve seat 13 is closed for shutting off the supply of low speed fuel when the rate of closing the throttle valve reaches a predetermined value. Then, a signal is issued to the solenoid valve 12 which is therefore closed, when the vehicle speed is gradually decreased to a value lower than a predetermined vehicle speed. |
