Abstract
PURPOSE: To make an improvement of performance of the engine with the fuel injection quantity controlled in high precision, by operating an electromagnetic mechanism for controlling an opening degree of the variable throttle valve in accordance with the detected signal of an air-fuel ratio, which is detected from the constituent of exhaust gas of the engie.
CONSTITUTION: Judging an output voltage of the air-fuel ratio sensor 8 for whether above or below the set value, to discriminate a mixture, fed to the engine 1, for whether rich or lean, the sensor 8 produces a high voltage for a rich mixture. This voltage, if inputted to a control circuit 70, is pulse-modulated by a duty ratio control circuit 70c, and the pulse voltage, after being amplified by a driver circuit 70d, is applied to a three-way solenoid valve 60, with a fuel injection quantity decreased to increase the air-fuel ratio. Thus with the fuel injection quantity controlled in high precision and an injection operated from a fuel injection nozzle 10 to correctly maintain the air-fuel ratio, an effectiveness of fuel consumption improvements of the engine can be displayed.
