Abstract

PURPOSE: To save fuel and improve precision control of air fuel ratio, by setting a check valve between a return hole and the upper portion of an accelerating fuel passage close to an inlet of an accelerating nozzle.
CONSTITUTION: Adjusting control of an adjusting screw 20 in a return hole 18 can provide high precision adjustment of differential fuel for acceleration on while removing the influence of bubbles, and a check valve 21, set between a passage communicated with an accelerating nozzle 17 and the return hole 18 facing the adjusting screw 20 through an adjusting clearance, can prevent deterioration of controllability and uniformity of air fuel ratio due to the reversed flow air caused by the return hole 18 in case of power operation with increased opening of a throttle vavle 1. An air bypass passage 23, set on the outlet side of an orifice 22 through a check valve 24, can prevent uncontrollableness of air fuel ratio due to injection of fuel from the accelerating nozzle 17 in accordance with the increase of suction air to the engine at the time of power operation.
