Method for controlling fuel of a spark ignited engine while regenerating a particulate filter

Method for controlling fuel of a spark ignited engine while regenerating a particulate filter

A system for filtering and oxidizing particulate matter produced by a gasoline direct injection engine is disclosed. In one embodiment, engine cylinder air-fuel is adjusted to allow soot to oxidize at an upstream particulate filter while exhaust gases are efficiently processed in a downstream cataly...
