Abstract:
An engine charge air-cooling system with water fumigation for an internal combustion engine includes a charge air cooler having a housing, a heat exchanger core, an air inlet and an air outlet. The charge air cooler inlet is connected to an outlet of 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 cylinder intake ports of the engine. The cooler intake header is adapted to receive water in a passage below the cooler inlet. Hot, compressed charge air entering the charge air cooler through the intake header mixes with water vapor formed in the header, thereby humidifying the charge air that enters the cylinders from the charge air cooler. The high, energy absorbing capability of the water molecule reduces the peak combustion temperature, thereby reducing Nox production in the combustion reaction.

Abstract:
The present disclosure generally relates to a locomotive diesel engine and, more particularly, to a heavy particle oil separator splash shield. Specifically, provided is a system and method for reducing exhaust particulate emissions. The present shield prevents large oil droplets in close proximity to the oil separator from easily entering the element, thus preventing less saturation of the oil separator and increasing the efficiency of the oil separator. As a result, environmental pollution is reduced.
