Abstract

PURPOSE: To provide the subject device wherein an ide-up fuel passageway is newly provided in a fuel supply system by branching the same from the upstream side of a low-speed fuel adjusting screw, thereby making the idle burning ratio at the idle-up time adequate.
CONSTITUTION: In an ordinary idling state, an idle-up switch 15 is "OFF", and an electromagnetic valve 7 communicates a negative circuit A to the atmospheric air. When the above mentioned switch 15 is turned on, the electromagnetic valve 7 transmits the negative pressure within the suction pipe to a negative pressure chamber 6 of an electromagnet by way of an idle-up diaphragm 5 a suction pipe negative pressure circut B and a negative circuit A, and the diagram is slightly opens a throttle valve 4 to realize an engine rotating speed corresponding to the cooler idling. Upon this occasion, since the negative pressure circuit A is communicated with an operating circuit E a negative pressure valve 12 is actuated by the suction pipe negative pressure to open the idle-up fuel passage way F, and idle-up fuel corresponding to the increased sucked up air quantity by the opening of the throttle valve 4 is supplies, and idle burning ratio is adequate.
