ABSTRACT:
A closed loop air/fuel ratio controller for an internal combustion engine is disclosed in which a proportional term is based on a fast filtered air/fuel ratio signal and an integral term is based on a slow filtered air/fuel ratio signal as well as the magnitude of the air/fuel ratio error outside of a deadband and the rich-lean conditions of the fast and slow air/fuel ratio signals.
