摘要： An exhaust gas recirculation (EGR) system for an internal combustion (IC) engine. The EGR system has a first cooler configured to cool exhaust from an exhaust system of the IC and to drain exhaust liquid formed by the cooling. The EGR system has a mixture chamber configured to mix exhaust cooled by the first cooler with intake air to form an exhaust-air mixture. The EGR system has a second cooler configured to cool the exhaust-air mixture. The EGR system has a heat exchange system for circulating and cooling coolant fluid used by the first and second coolers, and includes a split valve configured to divide coolant fluid flow between the first and second coolers. The EGR system has an engine control module configured to adjust the split valve based on comparing a temperature of the exhaust-air mixture to a determined dewpoint temperature of the exhaust-air mixture.

摘要： An exhaust gas recirculation structure includes an EGR cooler and an EGR duct, and the EGR duct includes an inflow portion into which the exhaust gas flowing out from the EGR cooler flows, a flow path, and an outflow portion from which the exhaust gas flows out. The flow path is provided such that the height on the side of the inflow portion is lower than the height on the side of the outflow portion, and has a region in which the distance between the center line of a flow path cross section of the flow path and a line along the lowest end in the height direction gradually increases from the outflow portion side toward the inflow portion side.
