PURPOSE:To improve the engine response under low load by recirculating fuel at the downstream of suction to suction upperstream position while closing the fuel recirculation path under low load. CONSTITUTION:A fuel recirculation path 8 for catching non-gasified liquid fuel and returning to the suction upper stream position is provided between a blower 4 and an air flow meter 5. One end 8a of said path 8 is connected to a liquid fuel catching section 10 having dish-shaped cross-section formed in the wall face of a suction path 1 positioned in the fuel injecting direction. At the intermediate position of said path 8, a control valve 9 equipped with a valve body 14 energized in the direction to choke a valve port 8c at the liquid catching section 10 of said path 8 is provided. |
