| 发明名称 | 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. | ||

| 主权项 | 1. A method, comprising: selectively routing exhaust from only a subset of engine cylinders to an exhaust passage via a first valve and to an intake passage via a second valve; obtaining one or more of a pressure or a temperature of the exhaust from the subset of engine cylinders; and indicating an engine component condition based on the one or more of the pressure or temperature. | ||
