Abstract: Various systems and methods are provided for exhaust gas recirculation. In one example, an exhaust gas recirculation (EGR) system includes an EGR passage coupling an engine exhaust system to an engine intake system, a first EGR cooler positioned in the EGR passage, the first EGR cooler configured to cool EGR with a first fluid, and a second EGR cooler positioned in the EGR passage downstream of the first EGR cooler, the second EGR cooler configured to cool EGR with a second fluid.

Abstract: Various methods and systems are provided for cooling exhaust system components. In one example, a system comprises heat shield surrounding at least a part of an engine exhaust passage valve positioned in an engine exhaust passage of an engine, and an air jet configured to direct compressed air into the heat shield. The heat shield contains the compressed air around an exterior of the at least the part of the engine exhaust passage valve.
