を特徴とする電子制御式燃料噴射装置。A basic injection amount setting means for setting a basic injection amount of fuel from an intake air amount and an engine speed; a starting amount increase setting means for increasing the injection amount and setting the increase ratio to a larger value as the engine temperature is lower; and gradually reducing the injection amount set by the starting amount increasing setting means over a predetermined time from the time of complete engine explosion. and a means for setting an increase in amount after starting to gradually increase the increase value from zero to the predetermined increase value over a set time within the predetermined time immediately after complete explosion when the engine is idling, and after the set time has elapsed, the increase value is increased to the predetermined increase value. The present invention is characterized by comprising an idle increase setting means for setting an increase value, and an idle increase correction means for lengthening the set time for the idle increase as the engine temperature is lower to make the rising slope of the idle increase gentler.
