Abstract
A control system for an engine comprising a turbocharger includes a throttle valve, 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 a first position whereby exhaust flow is routed to the CLOC in a CLOC mode; determine, based on operation in the CLOC mode, a pressure drop within the turbocharger; and command the actuator to move resulting in increased airflow into the engine while in the CLOC mode.
