METHOD FOR CONTROLLING FUEL OF A SPARK IGNITED ENGINE WHILE REGENERATING A PARTICULATE FILTER |
| 摘要 |
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 catalyst.
