Abstract
Abstract An engine power enhancement/pollution control system which utilizes a vortex air separator. The invention comprises a compressor for receiving air from the environment and providing high pressure air output. The high pressure air output is cooled to partially liquefied air having a mass fraction of less than 30% liquid. A vortex air separation apparatus is provided for separating the partially liquefied air into gaseous nitrogen enriched air and liquid oxygen enriched air. The oxygen enriched air is introduced to an internal combustion engine, thereby enhancing the power of the engine and minimizing pollution thereof.
