• means for detecting a fully closed state of a throttle valve disposed in an intake pipe of the engine;
• means for detecting an engagement between an output shaft of the engine and a driving wheel of a vehicle;
• means for increasing a rate of fuel supply by said supply means when said throttle valve is found to be fully closed by said closed state detecting means and when said engagement detecting means detects the engaging state between said output shaft and said driving wheel;
• means for detecting an operative state of a brake device mounted on the vehicle;
• and
• means for limiting said increase in rate of fuel supply by said increasing means when the operative state of the brake device is detected by said brake detecting means.
