METHOD AND ARRANGEMENT FOR RECIRCULATION OF EXHAUST GASES OF A COMBUSTION ENGINE

摘要

The invention relates to a method and an arrangement for recirculation of exhaust gases of a combustion engine (10) with a turbocharger (50). A first cooler (82) is adapted to make a heat exchange between the exhaust gases of a return line (3) led through a first path of the first cooler (82), and the exhaust gases 'of the exhaust line (2) downstream of the turbine (54) of the turbocharger unit (50) with respect to the intended direction of the exhaust gas flow in the exhaust line (2) led through a second path of the first cooler (82), wherein the first path and the second path of the first cooler (82) are cleaned by nitric dioxides (N02) produced in an oxidation catalyst (32) upstream of the turbine (54) of the turbocharger unit (50) with respect to the intended direction of the exhaust gas flow in the exhaust line (2).
