  • Intercooler having condensate reservoir
    Patent number: 8307643
    Abstract: An engine air intake system for a vehicle having an internal combustion engine may include a turbocharger; a CAC heat exchanger having an inlet end for receiving compressed intake air from the turbocharger and an outlet end; a remote condensate reservoir spaced from the CAC heat exchanger, for storing condensate therein; a condensate drain tube extending from the outlet end to the remote condensate reservoir to allow condensate produced in the CAC heat exchanger to flow into the remote condensate reservoir; an air duct connecting the outlet end to the engine to direct air flow from the outlet end to the engine; and a reservoir outlet hose connected to the remote condensate reservoir at a first end and connected to the air duct at a second end to allow condensate evaporating from the remote condensate reservoir to flow through the reservoir outlet hose into the air duct.
    Type: Grant
