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, an EGR cooler positioned in the EGR passage, a recirculation passage coupling an outlet of the EGR cooler to an inlet of the EGR cooler, an EGR cooler recirculation valve positioned in the recirculation passage and controllable to change a flow of exhaust gas though the recirculation passage, and a controller configured to adjust a position of the EGR cooler recirculation valve based on a temperature at the inlet of the EGR cooler.
