An engine cooling system may include a housing forming an enclosed duct having an air intake opening, an air intake door, an exhaust opening, and an exhaust door; at least one heat exchanger positioned within the duct such that ambient air entering the air intake opening flows through the duct to contact the at least one heat exchanger and exits the duct through the exhaust opening; and a controller connected to vary a degree that one or both of the air intake door and exhaust door is open to modulate a mass flow rate of ambient air contacting the at least one heat exchanger to vary a heat transfer from the at least one heat exchanger to the ambient air in the duct to maintain a temperature of a fluid within the at least one heat exchanger within a preferred temperature range.

Engine cooling system

An air charge system for an internal combustion engine may include a charge path having a charge inlet configured to receive air, and a charge outlet configured to convey air to an intake of the internal combustion engine; a first compressor in the charge path, the first compressor being driven by a motor and configured to receive the air from the charge inlet and increase temperature, pressure and volumetric flow rate of the air in the charge path; a first valve in the charge path downstream of the first compressor configured to divert at least a portion of the air leaving the first compressor from exiting the charge path through the charge outlet; and a controller configured to modulate at least one of the first valve and a speed of the motor to adjust a volumetric flow rate of air leaving the charge outlet.

Air charge system and method for an internal combustion engine

An engine cooling system may include a housing forming an enclosed duct having an 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 circulating coolant for the engine, at least one radiator positioned in the duct such that ambient air entering the air intake opening contacts at least one radiator, and the duct configured to include an 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 heat exchanger and the radiator, and exits the duct through the exhaust opening.
