Abstract:
1. A system for separating and dispersing condensate formed in a charge air cooler, comprising: a turbocharger compressor inlet duct; a turbocharger attached to an engine; a charge air cooler connected to the turbocharger; a condensate drain defined in the charge air cooler; a condensate reservoir defining a condensate inlet, a condensate outlet, and a charge air recirculation outlet; a condensate supply tube having a first end that is directly connected to the condensate drain of the charge air cooler and a second end that is directly connected to the condensate inlet of the condensate reservoir, providing fluid communication therebetween; a condensate dispersion tube directly connected to the condensate outlet of the condensate reservoir, the condensate dispersion tube having an inner surface and an outer surface that defines a circumferential wall, the circumferential wall defining a plurality of apertures in communication with the inner and the outer surfaces; a plurality of nozzles, wherein one of each of the plurality of nozzles is connected to one of each of the plurality of apertures; a shut-off valve connected directly to the condensate dispersion tube between the condensate reservoir and the plurality of nozzles, the shut-off valve movable between a closed position where fluid flows through the condensate dispersion tube is prohibited and an open position where fluid flows through the condensate dispersion tube is allowed; a condensate level sensor directly connected to the condensate reservoir that generates a signal when a condensate level is at a first predetermined level; a control unit in communication with the shut-off valve, the control unit moving the shut-off valve to the closed position when the condensate is below the first predetermined level, the control unit moving the shut-off valve to the open position when the condensate is above the first predetermined level and when the engine is operating at high load conditions; and a charge air recirculation tube having a first end directly connected to the charge air recirculation outlet of the condensate reservoir and a second end connected to the turbocharger compressor inlet duct, providing a pressure differential necessary to draw condensate from the charge air cooler into the charge air cooler reservoir.
