Abstract
An efficient stirling engine comprises an expansion chamber with a heater and a compression chamber with a cooler, wherein the two chambers are connected through a regenerator. A passage between the heater and the expansion chamber is provided with a first valve system, a passage between the cooler and the compression chamber is provided with a second valve system, the first valve system can close or open the passage between the heater and the expansion chamber, and the second valve system can close or open the passage between the cooler and the compression chamber. After adopting the structure above, when a heating end is heated to expand, a cooling end at the other end is closed, and on the contrary, when the cooling end is cooled to shrink, the heating end at the other end is closed, so that the heating energy is fully used, so as to increase the efficiency of the stirling engine.
