Abstract
PURPOSE: To feed a main fuel of proper gas-liquid ratio over a wide suction gas flow rate range by providing a bleed hole in an emulsion tube wall and a nozzle orifice thereover.
CONSTITUTION: A bleed hole 12 is formed in the wall of an emulsion tube 11 and a bleed hole 17 is formed in a nozzle orifice 16. With suction gas flowing in a venturi portion 9 to develop a negative pressure at the orifice 16, the air sucked in from a main air bleed 10 flows into the venturi portion 9 through the hole 17. With the suction gas flow rate in the venturi portion 9 increased to a medium extent, bleeding is started; air is injected into the tube 11 and suckes up the liquid fuel in the tube 11 to form a gas-liquid mixture which flows into the venturi portion. Mixture gas according to the engine revolution rate can be fed smoothly.
