Abstract
A control system for an engine comprising a turbocharger includes a cold light off catalyst (CLOC), a CLOC valve, an oil control 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 oil control valve regulates lubrication oil from the engine to the turbocharger. 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 of the turbine of the turbocharger; compare the determined pressure to a pressure threshold; determine a target position of the oil control valve to mitigate oil leakage from the turbocharger during CLOC operation; and command the oil control valve to the target position.
