Abstract
An external combustion engine comprises a container () with a working liquid () sealed therein in a state adapted to flow, a heater () for heating and vaporizing the working liquid () in the container (), and a cooler () for cooling and liquefying the vapor of the working liquid () heated and vaporized by the heater (). The displacement of the working liquid () caused by the vapor volume change is output as mechanical energy by being converted into the mechanical energy. A pressure regulating liquid () is sealed in a pressure regulating container () communicating with the container (). A pressure regulating unit () regulates the internal pressure (Pt) of the pressure regulating container (). A control unit () controls the pressure regulating unit () in such a manner that the internal pressure (Pt) is decreased in the case where it is higher than the saturation vapor pressure (Ps) of the working liquid () at the temperature (T) of a heated portion () of the container for vaporizing the working liquid (), while the internal pressure (Pt) is increased in the case where it is lower than the saturation vapor pressure (Ps).
