Abstract
PURPOSE: To obtain an optimal air-fuel ratio throughout the entire operational range of engine, by providing a subsidiary main jet in carburetor in parallel with the main jet and controlling the subsidiary main jet on the basis of the supercharging pressure or the density of exhaust gas.
CONSTITUTION: A subsidiary main jet 27 is provided in carburetor in parallel with main jet 26, in the manner that the outlet sides of these two jets are connected commonly to main nozzle 15. Inlet side of subsidiary main jet 27 is arranged to be opened or closed by solenoid valve 28, which is on-off controlled by control box 25 in response to the output signal of supercharging-pressure detector 23 for detecting the pressure of air supercharged by compressor 2. With such an arrangement, solenoid driving signals having different on-off time periods are produced from control box 25 in response to increase or decrease of the supercharging pressure for supplying a proper amount of fuel from subsidiary main jet 27, so that an optimal value of air-fuel ratio can be obtained.
