Abstract
A closed-loop mixture control system for an internal combustion engine includes an exhaust composition detector to provide information on the air-fuel ratio of the mixture to be controlled and a circuit arrangement which clamps the system to a rich mixture ratio when the operating characteristic of the composition detector becomes abnormal due to either an open or short circuit condition.
