ABSTRACT:
A control system in an automobile has a controller to provide an air-to-fuel ratio leaner than an ideally combustible air-to-fuel ratio when a lean control range of engine operating conditions is detected, and a controller to increase an air flow rate so as to enrich a fuel mixture when an engine operating condition is transitional to the lean control range. The control system conducts sequentially the lean control and the enrich control according to transitional patterns to the lean control range.
