研制出一种电子控制的闭合回路的化油器系统。这种系统空燃比的控制是以控制渗入空气为特色的。并用调节固定频率启闭的电磁阀来控制渗入空气量。实际应用时,频率最好超过30赫兹。对化油器、电磁阀以及控制单元作了某些改进和发展。将这种系统应用到有02传感器的三用催化系统上,汽车的排放量能符合1978年日本标准。 Developed a closed circuit electronic carburetor system. The control of air-fuel ratio of this system is controlled by the infiltration of air features. And adjust the fixed frequency solenoid valve to control the infiltration of air volume. In practice, the frequency is better than 30 Hz. The carburetor, solenoid valve and control unit made some improvements and development. Applying this system to a three-way catalytic system with 02 sensors, the vehicle’s emissions are in line with the 1978 Japan standard.
