<p>An engine charge air-cooling system with water fumigation for an internal combustionengine includes a charge air cooler having a housing, a heat exchanger core, anair inlet and an air outlet. The charge air cooler inlet is connected to an outletof a compressed air source, such as a turbocharger, through a cooler intake header. The charge air cooler outlet is connected through a cooler outlet header to cylinderintake ports of the engine. The cooler intake header is adapted to receive waterin a passage below the cooler inlet. Hot, compressed charge air entering the chargeair cooler through the intake header mixes with water vapor formed in the header,thereby humidifying the charge air that enters the cylinders from the chargeair cooler. The high, energy absorbing capability of the water molecule reducesthe peak combustion temperature, thereby reducing Nox production in the combustionreaction.</p> |
