An electronically controlled closed-loop carburetor system has been developed. This system's air-fuel ratio control is characterized by the air bleeds being controlled by turning the solenoid valves on and off at a constant frequency. The frequency above 30 Hz was desirable for practical performances. Some improvements and developments were made to the carburetor, the solenoid valve and the control unit. In application of this system to a three-way catalytic system with O2 sensor, the emissions met the 1978 Japanese standards.
