Abstract (en)
[origin: WO8801016A1] Method for reducing the nitric oxide emissions of the exhaust gases from a diesel engine by means of a controlled recirculation of the exhaust gases, which are cooled off and humidified in a water bath. According to the invention, the exhaust gases created in the diesel engine (1) are conducted into the wet cleaner (3), and part of the exhaust gases conducted into the wet cleaner (3) are returned to the suction duct (10) of the diesel engine, so that the amount of the recirculated exhaust gas is maintained constant with respect to the total exhaust gas volume.
