Abstract
The invention relates to a method for cleaning exhaust gases from a combustion engine, in which method humid air is fed into the combustion chamber of the combustion engine. In order to reduce nitrogen emissions effectively, particularly when a diesel engine is running at partial power, and in order for the method to be very accurately adjustable to meet the requirements of each particular engine application and use, in accordance with the invention, a mixture of gas and aqueous mist is fed with a spray head (3) into a space (2), which leads to the combustion chamber. The method can be readily implemented by an apparatus, which can be mounted in a small space without having to make substantial changes in the combustion engine. The invention also relates to an apparatus for cleaning exhaust gases from a combustion engine.
