摘要： An arrangement for exhaust gas recirculation and turbocharging for an internal combustion engine comprising a low-pressure turbocharger (3) and a high-pressure turbocharger (4), an exhaust gas recirculation duct (5) having its starting point in an exhaust gas duct (2) upstream from the turbine (4a) of the high-pressure turbocharger(4)and its end point in an air intake duct (1) between the compressors(3b, 4b)of the turbochargers (3, 4), a control valve(6)for controlling the amount of exhaust gas to be recirculated, and a cooler (7) for the in take air located in the air intake duct (1) between the compressors (3b, 4b) of the turbochargers(3, 4). The arrangement also comprises a scrubber (10) for cleaning the recirculated exhaust gas before the exhaust gas enters the compressor (4b) of the high-pressure turbocharger(4). The invention also relates to a method for exhaust gas recirculation and turbocharging.

摘要： The invention relates to a method for removing particles from exhaust gas from an exhaust gas flow of an internal combustion engine (1 ). The exhaust gas from an internal combustion engine (1 ) is led to an exhaust gas particle cleaning device (9). In order to allow for efficient particle removal from the exhaust gas, water super saturation is provided in the exhaust gas particle cleaning device. The exhaust gas particle cleaning device is provided with a higher temperature section and a lower temperature section causing particle growth at the lower temperature section.

摘要： An arrangement for treating exhaust gases of an internal combustion piston engine in a marine vessel, includes an exhaust gas channel coupled at its first end to the engine and having its second end opening to the environment, and a scrubber unit arranged between the first end and the second end of the exhaust gas channel. The arrangement has an exhaust gas channel cleaning system arranged to apply cleaning liquid on inner surface of the exhaust gas channel to a portion of the exhaust gas channel between the scrubber unit and the second end of the exhaust gas channel.
