Abstract: 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).

Abstract: A method for controlling a spraying apparatus, especially a spraying apparatus designed for the humidification of intake air, said apparatus comprising at least two spraying nozzles (1a, 1b, 1c, 1d) for injecting liquid into the intake air. In accordance with the control system's instructions, when the required amount of liquid to be supplied through the nozzles increases, liquid flow passages are opened for more nozzles (1a, 1b, 1c, 1d) and/or the liquid flow is directed into a flow passage leading to a nozzle that permits a larger liquid flow through it per unit of time, and when the required amount of liquid to be supplied through the nozzles decreases, liquid flow channels are closed at least for some of the nozzles (1a, 1b, 1c, 1d) and/or the liquid flow is directed to a nozzle that permits a smaller liquid flow through it per unit of time.

Abstract: The invention relates to a device for humidifying the intake air of internal combustion engines that are equipped with a turbocharger. The device comprises a humidifying unit (14, 16) through which the intake air and humidifying liquid flow and come into contact with one another. The humidifying unit is arranged upstream from the compressor (6) of the turbocharger in the direction of flow of the intake air. A heat exchanger (13, 15), which serves to pre-heat the intake air and through which the atmospheric intake air flows, is located upstream from the humidifying unit in the flow path of the intake air. Said heat exchanger is connected to a liquid circuit (11, 21) with which the humidified intake air that is compressed by the compressor and supplied to the internal combustion engine is cooled by another heat exchanger (9).

Abstract: An internal combustion engine includes an asynchronous injection valve configured to inject water into an intake port when one or more intake valves are closed and a synchronous injection valve configured to inject water into the intake port when the one or more intake valves are open. The asynchronous injection valve and the synchronous injection valve are configured to have injection characteristics that are different between the asynchronous injection valve and the synchronous injection valve.
