Nitrogen oxides reducing aftercooler for turbocharged engines

摘要

An aftercooler apparatus that is connected to a turbocharger and to a reciprocating engine has a primary and a secondary saturation chamber, and a drying chamber. Turbocharged air from the turbocharger is directed into the primary saturation chamber. The incoming air is initially mixed with and cooled by water located at the bottom of the primary saturation chamber before being directed through a diffusion screen. The air exiting the diffusion screen enters the secondary saturation chamber where intense bubbling and foaming increases the air-water contact area to further cool the air and form an air-water mixture approaching the temperature and moisture level of saturation. The air-water mixture is then directed into the drying chamber where a majority of the moisture is removed from the air through the use of centrifugal force. The now cooler moist air is directed toward the engine intake manifold, whereby the moisture in the air stream acts to reduce the NOx formation during the combustion process. The aftercooler apparatus acts to reduce the formation of NOx emissions from turbocharged engines rather than attempting to remove the NOx emissions from the exhaust stream of the engines. The aftercooler apparatus may also be used to beneficially recycle industrial waste waters.
