Abstract:
A system for reducing the formation of nitrogen oxides during the combustion process in a turbocharged engine, said engine having an intake manifold and a turbocharger for supplying compressed air to said intake manifold, said system comprising:a. means for increasing moisture within said compressed air to produce moist compressed air, disposed between said turbocharger and said intake manifold and being in fluid communication with said turbocharger and said intake manifold;b. wherein said moist compressed air is effective to reduce said formation of said nitrogen oxides during said combustion process;c. wherein said means for increasing moisture within said compressed air includes a saturation chamber having a lower portion and a water supply disposed in said lower portion of said saturation chamber such that when said compressed air is introduced into said saturation chamber, a portion of said water supply evaporates to increase moisture within said compressed air; andd. a drying chamber in fluid communication with said means for increasing moisture, said drying chamber having means for producing an air-water mixture having a temperature and moisture level approximate to that of saturation.
