To provide a Stirling engine mounted on a vehicle capable of cooling working fluid sufficiently when the vehicle runs, converting kinetic energy of the vehicle at braking time into temperature difference energy, and storing it to improve fuel economy.
This Stirling engine for driving the vehicle is provided with two pistons, and a phase difference changing mechanism 6 for changing relative phases of the pistons 1, 2 is installed as an operation condition changing device. A heat accumulator 5 is arranged in a heating part 12 of the engine, and a circuit for circulating a cooling medium provided with a radiator 22B, a heat transfer part temperature detector, and a cooling medium temperature detector is formed in a cooling part 22. When the vehicle applies the brake, an operation condition of the Stirling engine is switched by the phase difference changing mechanism 6 to operate as a heat pump, and the kinetic energy of the vehicle at braking time is stored in the heat accumulator 5 and the cooling medium as the temperature difference energy to utilize the energy at running time after that.
