Abstract
A control system for an engine comprising a turbocharger includes, a cold light off catalyst (CLOC), a CLOC valve, 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 controller is configured to command the CLOC valve to operate in a CLOC mode whereby exhaust flow is routed to the CLOC; determine, based on operation in the CLOC mode, a position of the CLOC valve; determine, based on the position of the CLOC valve, an available torque of the engine; and set a maximum available engine torque based on the determined available torque of the engine.
