Abstract
A control system for a vehicle powertrain having a normally aspirated engine includes an advanced device, a main catalyst, a cold light off catalyst (CLOC), a CLOC valve and a controller. The advanced device is positioned in an exhaust of the normally aspirated engine. The main catalyst positioned in the exhaust downstream of the advanced device. The CLOC is positioned in a bypass passage around the advanced device. The CLOC valve selectively routes exhaust flow from the normally aspirated engine between advanced device and the CLOC. The controller is configured to: determine a temperature of a main catalyst; determine, based on a temperature of the main catalyst being less than a temperature threshold, a first engine torque request; and command, based on the first engine torque request being less than a first torque threshold, the CLOC valve to operate in a CLOC mode.
