Title:
CRYOGENIC AIR COOLER FOR IMPROVING POWER AND FUEL EFFICIENCY OF A MOTOR VEHICLE INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2010/039517
Kind Code:
A3
Abstract:
A cryogenic air condenser is disclosed that pre-cools and thereby condenses air before it enters an internal combustion engine of a vehicle, allowing more fuel to be burned during each combustion cycle and enhancing the power of the engine without placing any drag on the engine. The air is cooled by making thermal contact with a cryogenic liquid, such as liquid nitrogen, liquid air, or liquid helium. For example, the air can flow through pipes surrounded by cryogenic liquid, or air can flow past pipes filled with cryogenic liquid. Cooling of the combustion chamber by the chilled air also allows higher compression ratios without dieseling, and slower burning of the fuel, thereby providing additional enhancements. The cryogenic air condenser requires no modifications to the engine, and can be added to a vehicle after manufacture. Evaporated cryogenic liquid can be vented into the vehicle exhaust, providing Venturi suction for additional cooling.
