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. Engine operation is interrupted when there are simultaneous signals indicating a carbon monoxide level above a predetermined value and and idling condition of the engine.
Claims12
A system for the interruption of the operation of a motor vehicle equipped with an internal combustion engine, including the steps of:
- means for sensing when the carbon monoxide level in the surrounding ambient rises above a predetermined value and providing a first output signal;
- means for recognizing an idling condition of the engine and providing a second output signal;
- and
- means for interrupting engine operation when the first output signal indicates a carbon monoxide level above the predetermined value and the second output signal indicates an idling engine.
