For its ideal approaching Carnot efficiency and wide acceptance of heating resources, Stirling engines are foreseen to be the eternal promise in the future. However, in practical use, Stirling engines still own the drawbacks of high cost and low thermal efficiency. The aim of this article is trying to solve these problems and give advice of how to improve the efficiency and reduce the cost. This article analyses the causes of these drawbacks from three aspects, vibrations, energy loss and regenerators. For each aspect, this article detailly talks about their causes, influence, and solutions. In the end, a comprehensive advice is given to improve the performance of Stirling engines with multiple ways ---- solving vibration problems with the method of ATMD, using β-type or γ-type Stirling engines, modified pistons and sidewall combustion chamber to reduce heat loss, and choosing the proper material and porosity for regenerators for different temperature.
