Abstract
A control system for an engine comprising a turbocharger includes a cold light off catalyst (CLOC), a main catalyst, a CLOC valve, a first and second oxygen sensor, and a controller. The CLOC is positioned in a bypass passage around a turbine of the turbocharger. The CLOC valve selectively routes exhaust flow from the engine between the turbine and the CLOC. The first oxygen sensor is disposed between the CLOC valve and the CLOC. The second oxygen sensor is disposed between the CLOC and the main catalyst. A position of the CLOC valve is determined and a priority is assigned to one of the first and second signals of the oxygen sensors based on the position of the CLOC valve. An engine out lambda is determined based on the first and second signals and assigned priority. An engine parameter is commanded.
