COOLER BYPASS TO REDUCE CONDENSATE IN A LOW-PRESSURE EGR SYSTEM

摘要

Various systems and methods are described for an exhaust gas recirculation (EGR) system including an EGR cooler coupled to a turbocharged engine in a vehicle. One example method comprises, under selected operating conditions, controlling a mixture temperature of cooled and uncooled EGR at a mixing location upstream of an intake passage inlet by routing at least a portion of exhaust gas through a bypass around the EGR cooler.
