ABSTRACT:
Emission control apparatus for an internal combustion engine includes a sensor for detecting the concentration of an exhaust composition to generate an error correction signal for controlling the air-fuel mixture ratio at a predetermined value to minimize noxious exhaust emissions and a transient compensation circuit to provide a step function voltage to compensate for transient engine operating condition in response to a sensed change of engine load.
