Abstract
A carburetor has an apparatus for compensation of idling revolution of an internal combustion engine. The apparatus comprises a bypass passage one end of which is opened to the air suction conduit of the carburetor upstream of a throttle valve, the other end opened to the same downstream of the throttle valve. A fuel passage supplies fuel into the bypass passage to form a fuel-air mixture, a solenoid valve provided on the bypass passage for controlling a quantity of the fuel-air mixture in response to operation of a load such as, for example, heater, a radiator fan, lights, an air conditioner, etc. so that the idling rotational speed to be decreased by such operations is compensated by supplying fuel-air mixture into the air suction conduit.
