Abstract
A charge air management system for an automotive engine includes a charge air-to-liquid coolant heat exchanger for receiving refrigerated liquid coolant from a reservoir. The liquid coolant is refrigerated by means of an engine driven refrigerant system including a compressor, a condenser, and an evaporator mounted within the reservoir.
Claims17
A charge air management system for an automotive engine, comprising:
- a coolant reservoir containing a quantity of liquid coolant;
- a refrigeration system for removing heat from the liquid coolant within the reservoir;
- and
- a charge air-to-liquid coolant heat exchanger for receiving refrigerated coolant from the reservoir and for chilling charge air entering the engine.
1 more element
A charge air management system for an automotive engine, comprising:
- an engine driven booster for increasing the quantity of charge air entering the engine's air inlet;
- a coolant reservoir containing a quantity of liquid coolant;
- a refrigeration system for removing heat from the liquid coolant within the reservoir;
- and
- a charge air-to-liquid coolant heat exchanger, positioned between the booster and the air inlet, for receiving refrigerated coolant from the reservoir and for chilling charge air entering the air inlet.
2 more elements
A method for providing charge air to an automotive engine, comprising the steps of:
- increasing the quantity of air entering the engine by means of an engine driven booster;
- increasing the density of the charge air leaving the booster by passing the charge air over a charge air-to-cooling liquid heat exchanger positioned between a booster outlet and an air inlet for the engine;
- providing the charge air-to-cooling liquid heat exchanger with a supply of cooling liquid maintained within a reservoir at a sub-ambient temperature;
- and
- refrigerating the cooling liquid within the reservoir by means of a refrigeration system powered by the engine.
