ABSTRACT:
A carburetor for supplying the mixture of optimum air-fuel ratio to the engine at all times under any accelerating condition. The carburetor comprises a fuel adding valve and associated valve mechanism whereby when the vacuum pressure in the suction pipe decreases as a result of acceleration, the fuel adding valve is opened to deliver extra fuel in addition to the main fuel to produce the mixture of optimum richness. With this invention, the conventional drawback can be precluded that after the first stage of acceleration the mixture becomes leaner than is required.
