| description | A vehicle propulsion system includes an internal combustion engine with a first combustion chamber and a second combustion chamber, a catalytic converter in an exhaust stream in communication with an exhaust of the internal combustion engine, a gasoline particulate filter in the exhaust stream downstream of the catalytic converter, and a controller in communication with the internal combustion engine. The controller is programmed to determine if a soot loading of the gasoline particulate filter exceeds a predetermined threshold, and adjust a set of engine operating parameters of the internal combustion engine to disable combustion in the first combustion chamber and enrich a fuel mixture in the second combustion chamber if the soot loading in the gasoline particulate filter exceeds the predetermined threshold. |
