An external combustion engine including a container 10 sealed with a working medium 14 in liquid phase adapted to flow, a multiplicity of evaporators 201 to 204 for heating and evaporating part of the liquid-phase working medium 14 , a multiplicity of condensers 221 to 224 for cooling and condensing the working medium 14 evaporated in the evaporators 201 to 204 , and an output unit 11 for outputting by converting the displacement of the liquid-phase portion of the working medium 14 into mechanical energy. The multiplicity of the evaporators 201 to 204 share a heat source from which heat is supplied thereto. The engine further includes an influent liquid amount regulation unit whereby the liquid-phase portion of the working medium 14 in a greater amount flows into the evaporators nearer the heat source upon displacement of the liquid-phase portion of the working medium 14 toward the multiplicity of the evaporators 201 to 204 from the output unit 11 , while the influent liquid amount is smaller for the evaporators farther from the heat source. In this way, heat loss is reduced resulting in improved efficiency.
