发明名称 AIR-FUEL RATIO CONTROLLER FOR INTERNAL-COMBUSTION ENGINE
摘要 PURPOSE:To suppress the formation of carbon monoxide gas etc. by installing a means which can control the air-fuel ratio in warming always to an optimum value, independently of the dispersion of preparation accuracy and the secular change of a carburetor and the using environment of an internal combustion engine, onto the air-fuel ratio controller for the engine. CONSTITUTION:An air-fuel ratio controller is equipped with an oxygen sensor 30 for detecting the conc. of oxygen in exhaust gas, temp. sesor 31 for detecting the temp. of the cooling water 32 for engine, idle switch 33 which is turned ON when the opening degree of a throttle valve 8 is nearly perfectly closed, i.e., in idle operation, valve opening-degree detector 34 which outputs a voltage signal corresponding to the opening degree of the throttle valve 8, and an engine revolution-number detector 35. A control circuit 38 controls the air-fuel ratio in all operation state to a theoretical air-fuel ratio or a set value by changing the opening and closing state of each of a main fuel solenoid valve 14, slow fuel solenoid valve 18, and a jet fuel solenoid valve 22, on the basis of each output signal of an oxygen sensor 30- an revolution-number detector 35.
