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.

Abstract: A generator includes an engine, an air-fuel mixing device coupled to the engine, where the air-fuel mixing device is structured to receive air from an air intake and combine the air with fuel to create an air/fuel mixture, an exhaust outlet positioned on a first side of the generator and coupled to the engine, wherein the exhaust outlet is structured to emit exhaust gases from the engine, and a carbon monoxide (CO) sensor positioned on a second side of the generator opposite the exhaust outlet, where the CO sensor is structured to detect CO concentration near the generator.
