Internal combustion engine and method for exhaust gas aftertreatment of internal combustion engine

The invention relates to an internal combustion engine (10) with an intake manifold (20) and an exhaust device (40). The internal combustion engine (10) is designed as an internal combustion engine,in particular a gasoline engine, which is supercharged by means of an exhaust gas turbocharger (30). At least one three-way catalytic converter (46, 48) is arranged in the exhaust device (40) of the internal combustion engine (10). Furthermore, a low-pressure exhaust gas recirculation system (60) is provided that connects the exhaust device (40) downstream from a turbine (44) of the exhaust gas turbocharger (30) and upstream from the at least one three-way catalytic converter (46, 48) to the intake manifold (20) upstream from a compressor (32) of the exhaust gas turbocharger (30). The invention further relates to a method for exhaust aftertreatment of such an internal combustion engine (10). 本发明涉及一种具有进气管(20)和排气装置(40)的内燃机(10)。内燃机(10)设计为借助废气涡轮增压器(30)增压的内燃机、尤其是汽油发动机。在内燃机(10)的排气装置(40)中布置有至少一个三元催化器(46、48)。此外设置有低压废气再循环装置
