Intercooler having condensate reservoir
View Patent ↗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.
1. An engine air intake system for a vehicle having an internal combustion engine comprising:
a turbocharger;
a CAC heat exchanger having an inlet end configured to receive compressed intake air from the turbocharger and an outlet end;
a remote condensate reservoir mounted in the vehicle spaced from the CAC heat exchanger, configured to store condensate therein, and having a top surface;
a condensate drain tube extending from the outlet end to the remote condensate reservoir configured 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 and configured to direct air flow from the outlet end to the engine; and
a reservoir outlet hose connected to the top surface of the remote condensate reservoir at a first end and connected to the air duct at a second end and configured to allow condensate evaporating from the remote condensate reservoir to be drawn through the reservoir outlet hose into the air duct.
2. The engine air intake system of claim 1 wherein the condensate drain tube has a first end connected to the outlet end and a second end connected to the remote condensate reservoir at an elevation that is lower than the first end of the condensate drain tube.
3. The engine air intake system of claim 1 wherein the reservoir outlet hose has an inside diameter that is at least an order of magnitude smaller than an inside diameter of the air duct.
4. The engine air intake system of claim 1 wherein at least a portion of the condensate drain tube is made of silicone.
5. The engine air intake system of claim 1 wherein at least a portion of the reservoir outlet hose is made of silicone.
6. The engine air intake system of claim 1 wherein the condensate drain tube connects to a side of the remote condensate reservoir at an elevation below the top surface of the remote condensate reservoir.
7. An engine air intake system for a vehicle having an internal combustion engine comprising:
