  • Controlled condensate collection and evacuation for charge air cooler
    Patent number: 7980076
    Abstract: A condensate extractor assembly is provided for collecting and evacuating condensate from inside a charge air cooler in an internal combustion engine assembly. The condensate extractor assembly includes a sump that is attached to or formed in the charge air cooler. The sump is adapted to drain and collect condensate from the charge air cooler. A hose is fluidly coupled at one end to the sump, and fluidly coupled at a second end to the intake manifold. The hose is configured to evacuate condensate from the sump and distribute it directly to the intake manifold in response to the pressure gradient generated by the engine assembly when in an on-state. The hose defines an orifice that restricts the flow of air and condensate through the hose. A filter is fluidly coupled to the hose, fluidly intermediate the orifice and the sump member.
