Abstract
This invention teaches a system for interrupting operation of the internal combustion engine of a vehicle so as to prevent an undesirably high level of carbon monoxide in the ambient by using the voltage output signal from an engine oxygen sensor placed in the exhaust stream. Engine operation is interrupted when there are simultaneous signals indicating both an EGO sensor signal level above a predetermined value and idling condition of the engine.
