Abstract
A system for regeneration of a particulate filter in a V-pipe exhaust system includes a pair of post-converter universal heated exhaust gas oxygen (UHEGO) sensors disposed at a pair of pipes of the V-pipe exhaust system downstream from a pair of three-way catalytic (TWC) converters and the pair of post-converter UHEGO sensors measure lambda values. The system also includes an engine controller in communication with the pair of post-converter UHEGO sensors. The engine controller is configured to receive and compare measured lambda values from the pair of post-converter UHEGO sensors to a target exhaust gas lambda value for exhaust gas flowing into the particulate filter and provide at least one adjusted target exhaust gas lambda value as a function of a difference between the measured lambda values and the target exhaust gas lambda value.
