Methods and systems for exhaust gas recirculation |
摘要 |
Various methods and systems are provided for diagnosing an engine component condition in an exhaust gas recirculation system. In one example, a method includes selectively routing exhaust from a subset of engine cylinders to an exhaust passage via a first valve and to an intake passage via a second valve, and obtaining one or more of a pressure or temperature from the subset of engine cylinders. The method further includes indicating an engine component condition based on the one or more of the pressure or temperature. |
