System for utilizing waste heat of an internal combustion engine

Claim 1

Apparatus comprising in combination, 1. an internal combustion engine having a completely independent liquid primary cooling system including a rediator and cooling fan, and 2. apparatus for utilizing waste heat from said internal combustion engine comprising, a. supercharger means having an impeller mounted on said engine and situated in an air intake conduit of said internal combustion engine; b. turbine means driving said supercharger means and provided with a motive fluid inlet port and a motive fluid outlet port; c. vaporizer means intimately associated with said internal combustion engine, heated by said engine, and provided with a motive fluid outlet communicating with said motive fluid inlet port of said turbine means and provided with a motive fluid inlet; d. condenser means provided with a motive fluid inlet communicating via a confined flow passageway with said turbine outlet port and provided with a motive fluid outlet communicating with said vaporizer inlet, said condenser means being located in front of said radiator so that air circulating through said radiator also cools said condenser; e. a check valve means situated in said confined flow passageway between said turbine outlet port and said condenser inlet and permitting only unidirectional flow of motive fluid from said turbine means to said condenser means; f. said turbine means, vaporizer means and condenser means together defining a closed loop for circulating a motive fluid completely independent of the primary cooling system and of the fuel system of the internal combustion engine; and g. non-combustible motive fluid within said closed loop.
