Abstract:
A carbon monoxide detection system for vehicles having a motor controlled by an ignition switch, a speedometer, and a vehicle cab equipped with a driver's seat wherein the detection system comprises;an internal carbon monoxide sensor mounted on the interior of the vehicle cab;a computer operatively associated with both the internal carbon monoxide sensor and said ignition switch for terminating the operation of the vehicle motor in response to the levels of carbon monoxide gas sensed by said internal carbon monoxide sensor within the interior of the vehicle cab;an external carbon monoxide sensor mounted on the exterior of the vehicle cab and operatively associated with said computer and said ignition switch for termination of the operation of the vehicle motor in response to the levels of carbon monoxide gas sensed by the external carbon monoxide sensor on the exterior of the vehicle cab wherein said computer is operatively associated with said speedometer and both the internal and external carbon monoxide sensors to activate said internal carbon monoxide sensor in response to a selected output from said speedometer, and to activate said first external carbon monoxide sensor in response to a second selected output from said speedometer; and,a time delay mechanism interposed between said computer and said internal carbon monoxide sensor for delaying the activation of the internal carbon monoxide sensor in response to the first selected output from said speedometer.
