A convertor for a hot gas engine whereby such an engine may be more economically operated. The invention comprises an improvement to a standard hot gas engine including at least one combustion chamber and conduits for supplying a mixture of fuel and air to the combustion chamber comprising a heat sink disposed above the piston head, a fuel iris operatively mounted above the heat sink and a fuel flow controller connected to the heat sink and to the fuel iris for regulating the flow of fuel to the engine in response to the temperature of the heat sink. The improvement of this invention permits operation of the invention on residual heat, thereby permitting increased fuel economy. The invention further contemplates using the engine to power an alternator whereby electrical energy may be derived, stored and used for work.

1. In a hot gas engine including at least one combustion chamber and means for supplying a mixture of fuel and air to the combustion chamber, the improvement comprising: heat sink means disposed within the combustion chamber for improving the fuel efficiency of the engine; fuel iris means operatively mounted above said heat sink means whereby the transmission of combustion heat to and from said heat sink means may be regulated; and fuel flow controlling means connected to said heat sink means and said fuel iris means whereby the flow of fuel to the engine may be regulated in response to the temperature of said heat sink means. 2. The improved hot gas engine of claim 1 wherein said heat sink means comprises a metallic ring disposed within the combustion chamber, said heat sink means further comprising a plurality of metallic sleeves disposed within said ring in spaced apart, substantially transverse relation to the axis of said ring, each of said plurality of said sleeves including a heat storage material placed therein, whereby heat of combustion may be retained within said heat sink means. 3. The improved hot gas engine of claim 2 wherein said ring is formed from iron. 4. The improved hot gas engine of claim 2 wherein said ring is formed from copper alloy. 5. The improved hot gas engine of claim 4 wherein said plurality of sleeves are formed from cast iron. 6. The improved hot gas engine of claim 5 wherein said heat storage material comprises an inorganic metal compound. 7. The improved hot gas engine of claim 6 wherein said heat storage material comprises aluminum oxide. 8. The improved hot gas engine of claim 2 wherein said fuel iris means comprises a plurality of iris leaves, each of said leaves being movably attached to an iris operating ring, whereby rotation of said iris operating ring will open and close said fuel iris means. 9. The improved hot gas engine of claim 8 wherein said fuel flow controlling means comprises a fuel metering valve including a first fuel orifice and a second fuel orifice, said metering valve being movable to permit the flow of fuel through one of said first and second fuel orifices in response to temperature sensed within said heat sink means. 10. The improved hot gas engine of claim 9 wherein said fuel flow controlling means further comprises temperature sensing means mounted on said heat sink means metallic ring and electromechanically connected to said fuel metering valve to selectively position said valve at said first and said second fuel orifices. 11. The improved hot gas engine of claim 10 wherein said fuel flow controlling means further comprises an iris rod, one end of said rod being attached to said iris operating ring and the other end of said rod being electromechanically attached to said fuel metering valve to close said fuel iris means when said first fuel orifice is operable and to open said fuel iris means when said second fuel orifice is operable. 12. The improved hot gas engine of claim 11 further comprising transmission means operatively connected to said engine for translating engine power to work force. 13. The improved hot gas engine of claim 12 further comprising alternator means operatively connected to said engine for translating engine power to electrical energy. 14. The improved hot gas engine of claim 13 further comprising electrical energy storage means connected to the output of said alternator means for receiving and storing the electrical energy. 15. The improved hot gas engine of claim 14 further comprising electric motor means operably connected to said electrical energy storage means. 16. The improved hot gas engine of claim 15 further comprising switch means for controlling the operation of said alternator means.
