Abstract
An internal combustion engine-based system including an engine, a shutdown circuit coupled to the engine to shut down the engine, a controller in communication with the shutdown circuit, and a carbon monoxide (CO) sensor in communication with the controller. The controller communicates with the shutdown circuit to shut down the engine at a predetermined CO threshold concentration when the CO sensor provides the controller with signals that are representative of a CO level proximate the engine that indicate a trend of building CO levels over a set time interval.
