ABSTRACT:
Waste heat generated by an internal combustion engine is utilized by an apparatus comprising a supercharger, a turbine drivably engaging the supercharger, a vaporizer, a condenser and fluid injection duct means. The turbine, the vaporizer and the condenser form a closed loop within which a motive fluid is circulated. The vaporizer is intimately associated with the internal combustion engine, and the motive fluid within the vaporizer is converted to gaseous form by heat transfer from the engine. The vaporized fluid is then used to drive the turbine which, in turn, drives the supercharger, thereby increasing the efficiency of the engine. Spent motive fluid is recovered from the turbine, condensed, and recycled to the vaporizer. Additionally, a fluid injection duct introduces fluid preferably in the form of steam into the air which enters the engine.
