ABSTRACT:
This specification discloses an apparatus and method for controlling the air fuel ratio in an internal combustion engine. The instantaneous air fuel ratio is compared with the inverse of a prior art fuel ratio to determine if an adjustment is necessary. If the inverted prior state of the air fuel ratio is the same as the present state, no change to the air fuel ratio will occur. If the inverted prior state is not the same as the present state, a control correction in the air fuel ratio will occur. The system will not change control voltage if the predicted stated and the actual state of the air fuel ratio agree.
