Abstract
An apparatus for controlling the proportion of air and fuel in the air-fuel mixture of the internal combustion engine includes a carburetor having a main system fuel tube, a main system air-bleeding passage, a slow system fuel tube and a slow system air-bleeding passage, and a proportional control solenoid valve including an air-inlet port, a first outlet port communicating with the main system air-bleeding passage, a second outlet port communicating with the slow system air-bleeding passage and a moving-coil linear motor incorporated therein, wherein the proportional control solenoid valve is adapted to supply air to the main system air-bleeding passage and the slow system air-bleeding passage at a flow rate proportional to the level of the intensity of an electric current supplied to the moving-coil linear motor when the intensity of the electric current lies within a range between two predetermined values Imin and Imax.
