ABSTRACT:
A heat energy recovery system for cooling an internal combustion engine is characterized by separate oil and water circuits. The oil circuit is used to lubricate and cool the engine. A heat exchanger between the oil and water circuits cools the oil and produces steam from the water. The steam is used to power a steam engine in the water circuit which in turn is used to drive accessories normally driven by the engine. The recovery of heat from the cooling oil and the generation of energy via the steam engine reduces the load on the engine, decreasing its fuel consumption and increasing its net output to drive a vehicle.
