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.

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

System and method for regenerating a particulate filter

Various systems and methods are described for operating an engine in a vehicle in response to an ambient humidity generated from an exhaust gas sensor. One example method comprises, during engine non-fueling conditions, where at least one intake valve and at least one exhaust valve of the engine are operating, generating an ambient humidity from the exhaust gas sensor and, under selected engine combusting conditions, adjusting an engine operating parameter based on the ambient humidity.

Humidity detection via an exhaust gas sensor

Various systems and methods are described for controlling an engine in a vehicle which includes an exhaust passage and an exhaust gas recirculation system. One example method comprises adjusting an engine operating parameter based on an exhaust gas recirculation amount, the exhaust gas recirculation amount based on a first humidity and a second humidity, the first humidity generated from a first humidity sensor at a first location and the second humidity generated from a second humidity sensor located in the exhaust passage of the engine.
