Patent ID: 12012091

Abstract:
Although internal combustion engines typically waste about 75% of their fuel energy, this invention can provides 31% or more brake horsepower than the engine alone by using anhydrous organic racing engine coolant or other anhydrous organic heat transfer fluid arranged to spiral around a combustion chamber until heated to over 250° C. without boiling while exceeding the boiling point of a separate working fluid that is heated by coolant then superheated by exhaust gas before entering a unique positive displacement vapor expander engine having a piston connected by a clutch to a driveshaft that is also driven by the combustion engine to create a high efficiency direct mechanical powertrain which avoids losses of about 15% had a generator charged a battery powering an electric motor-generator connected for regenerative braking to charge batteries. Highly elevated coolant temperatures also reduce cylinder and exhaust temperatures to lower emission toxicity while preventing lubricant burnout.
