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 which would cause a low level of oxygen in the ambient. Engine operation is interrupted when there are simultaneous signals indicating an oxygen level below a predetermined value and an idling condition of the engine.
