Abstract

PURPOSE:To save fuel consumption of an engine, by providing feed fuel adjusting regulating valves in main and pilot fuel lines of a carburetor and performing automatic control of a mixture in accordance with speed of the engine and negative pressure in an intake pipe or negative pressure in the upstream side of a throttle valve in an air intake tube of the carburetor. CONSTITUTION:Fuel feed adjusting regulating valves consisting of a solenoid regulator valve 24, connected to a negative pressure switch 6 closing a circuit for intake pipe negative pressure of an engine at not lower than a certain degree of pressure, and solenoid regulator valve 13, connected to a negative switch 5 opening a circuit for intake pipe negative pressure of the engine at not lower than a certain degree of pressure, are provided respectively in a main fuel line 22 having a bypass air passage 23 and a pilot fuel line having a pilot mixture passage 12 in a carburetor 1. For instance, the negative pressure switch 5, for a large value of intake pipe negative pressure and high speed of the engine at deceleration time, and a speed sensor 4 closing a circuit, for not higher than a certain level of speed of the engine, are both opened, thus the valve 13 is closed not to feed unnecessary quantity of a pilot mixture. Further the switch 6 is opened at high loaded operation to close the valve 24 then supply of auxiliary air is ceased.
