摘要: An electronic type air/fuel ratio control system for use in gasoline engines comprises an accelerator, a detector of the manipulation angle of the accelerator, a shunt conduit by-passing a throttle valve, an air by-pass valve exposed in the shunt conduit for controlling flow rate of by-pass air, and a control circuit. The control circuit is responsive to the output of the accelerator manipulation angle detector and generates a control signal for the air by-pass valve, whereby the air/fuel ratio can be controlled with high accuracy when the flow rate of air is low.
