Abstract:
A charge air management system for an automotive engine, comprising:an air intake plenum for furnishing air to the engine; a first duct for furnishing air to the intake plenum; a second duct for furnishing air to the intake plenum; a charge booster for increasing the quantity of air entering the plenum from the second duct; a liquid-cooled intercooler for removing heat from air flowing through at least the second duct, with the intercooler being provided with liquid coolant chilled by an air-to-liquid heat exchanger which is exposed to ambient air, and with liquid coolant being allowed to flow through the air-to-liquid heat exchanger only if the temperature of the liquid coolant leaving the intercooler exceeds the ambient temperature by an amount greater than a predetermined threshold; and a splitter valve for controlling the relative proportion of air flowing into the plenum from the first and second ducts.
