ABSTRACT:
Turbocharged engine air supply cooling arrangement and method that utilizes an air-to-air heat exchanger provided with a fan to circulate ambient air about the heat exchanger to cool turbocharger compressor discharge air. The air is cooled to near, but above, the temperature of the ambient air as it passes through the heat exchanger. The air is then conveyed through a turbine which is mechanically connected to rotate the fan in response to the energy of expansion of the air. As the air expands through the turbine, it is cooled to a lower temperature, even below that of the ambient air before delivery to the engine.
