PURPOSE:To prevent a bubble generated by action of a solenoid valve from influencing the other fuel system, by providing an auxiliary fuel system, in which fuel is controlled by the solenoid valve, separately from a main fuel system with a low speed system branching and communicating the both main and auxiliary fuel systems with a common main nozzle. CONSTITUTION:Fuel is fed from a float chamber 2 in a carburetor 1 to a main nozzle 9 through a main jet 6, passage 5 and a well 8. And low speed system fuel, branching from the passage 5, is supplied from a slow port 15 and an idle port 16 through a passage 19, well 18 and a passage 17. While controlled auxiliary fuel is fed to the main nozzle 9 through a passage 10 and a well 14 from an auxiliary jet 11 duty ratio controlled by a solenoid valve 22. The valve 22 simultaneously controls low speed system bleed air by a valve body 26. A bubble of fuel, generated by opening and closing the auxiliary jet 11, gives no influence to the main fuel passage 5 and the low speed system passage 19. |
