Engine Cooling System

A vehicle comprising:

• an internal combustion engine;
• a compartment having an enclosed duct;
• the duct having an air intake opening to ambient air and an exhaust opening to ambient air aft of the air intake opening;
• at least one heat exchanger positioned within the duct such that ambient air entering the air intake opening contacts the at least one heat exchanger;
• at least one radiator positioned within the duct and configured to circulate coolant for the engine;
• wherein the exhaust opening positioned downstream of the at least one heat exchanger and the at least one radiator, such that ambient air flows in the air intake opening, through the duct to contact the at least one heat exchanger and the at least one radiator, and exits the duct through the exhaust opening;
• and
• wherein the vehicle is selected from an aircraft, a land vehicle, an amphibious vehicle a marine vehicle, and a submarine vehicle.

A method for cooling an engine having a housing forming an enclosed duct having an air intake opening and an exhaust opening, the method comprising:

• placing at least one heat exchanger within the duct;
• connecting the at least one heat exchanger to condition combustion air in a combustion air intake line to the engine;
• placing at least one radiator configured to circulate coolant for the engine within the duct;
• and
• modulating an amount of ambient air flowing through the duct to maintain temperatures of the combustion air and the coolant within preferred temperature ranges.
