A method and an arrangement for treating the inlet air (21) and exhaust gases (22) of a large supercharged internal combustion engine (9), especially a diesel engine, in a system, in which water in a suitable form, for instance as water vapor or water mist, is supplied after the compressor (8) to the inlet air of the engine for cooling and saturating the inlet air (21), and in which the exhaust gases (22) from the engine are conducted to an exhaust gas scrubber (1, 2) to be washed and cooled at least mainly by water. The exhaust gases (22) are cooled in the exhaust gas scrubber (1, 2) in order to condensate the water vapor in the exhaust gases and recover clean water and the thus recovered water is supplied to the inlet air (21) of the engine so that said cooling and saturating of the inlet air (21) is at least mainly provided by the water recovered from the exhaust gas scrubber (1, 2). |
