Because the Stirling engine has a low load following capability, it is difficult to use as a power, such as a car. In order to use the Stirling engine as the power of the car, it is necessary to not load control of the time lag in the continuously variable transmission. Continuously variable transmission to devise in this study occur without the time lag required minimum of low gear effect, depending on the load applied to the tire. Therefore, the engine takes only a certain following load, it can be extracted efficiently power. Although the Stirling engine requires a large flywheel in order to maintain the rotation, it is possible to reduce the flywheel to the limit by not loading the control of the time lag, it is possible to reduce the size and weight of the vehicle.
