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.
