Charge Air Cooler: Operation

The purpose of the charge air cooler is to reduce the air inlet temperature thereby increasing air density thus producing an increase in engine efficiency. The charge air cooler operates as an air-to-water heat exchanger. The charge air cooler extracts heat from the incoming compressed air, leaving the supercharger. Transfering the heat in the air to the to the coolant in the charge air cooler. The hot coolant is then circulated to the charge air cooler radiator where it is cooled.
