ABSTRACT:
This specification discloses an apparatus and method for controlling the air fuel ratio in an internal combustion engine in response to a feedback signal from an exhaust gas oxygen sensor. The sensor output signal is sampled periodically. Control of the air fuel ratio utilizes time based averaging of the oxygen sensor signal to generate an error signal which is proportional to the difference between the actual and desired air fuel ratio.
