Abstract

See full text

To provide a method of reducing a nitrogen oxide in an exhaust gas of an internal combustion engine, an apparatus for reducing a nitrogen oxide, and an internal combustion engine system that can effectively reduce a nitrogen oxide in the exhaust gas of the internal combustion engine in a simple manner. A method of reducing a nitrogen oxide in an exhaust gas of an internal combustion engine includes: a step of moisturizing air at a pressure equal to or lower than atmospheric pressure by bringing the air into contact with one surface of a steam permeable membrane (11) while flowing water along the other surface of the steam permeable membrane (11); and a step of introducing the moisturized air into the internal combustion engine.
