Abstract
PURPOSE: To prevent evaporating fuel from discharging at the low speed in such a way that dilution of air-to-fuel ratio at the high load is prevented by opening an air bleeding port on the upstream side of a main nozzle, in addition, a throttle and an expansion chamber are formed in the fuel path.
CONSTITUTION: An emulsion tube 11 which provides a throttle 12 and an expansion chamber 13 located at its upper part is inserted in a main system fuel path 5, particularly at the idling time of an engine, steam bubbles which have been prouced in the path 5 are prevented from bleeding through a main nozzle 4. Besides, an auxliary air bleeder 16 is arranged maintaining a clearance in the span between it and an air jet 14 which is located on the upper part of the expansion chamber 13, further an air bleeding tube 17 is opened between the jet 14 and the bleeder 16, and the other end of the bleeding tube is located opposite to the nozzle 4 at the straight upstream of the nozzle 4. Thus, fuel can be made particulate by air through an air bleeding port 18, and at the high load, air which flows through the air jet 14 can be decreased.
