ABSTRACT:
A carbon monoxide detector and deactivating mechanism to monitor the level of carbon monoxide concentration within the passenger compartment of a vehicle having an internal combustion engine, and to stop the operation of such internal combustion engine when the level of carbon monoxide concentration reaches a danger point for occupants of the passenger compartment. The detector includes plural detecting means to determine such dangerous concentration level, at least two of which detect carbon monoxide in the atmosphere by different methods and principles of operation. The detector is electrically connected to the vehicle's electrical system and when the critical pre-determined level of carbon monoxide is reached, it triggers a vacuum switch to interrupt the ignition circuit of the vehicle for a long enough time to insure that the internal combustion engine has been stopped.
