Abstract

The paper shows a digital model of a dwell mechanism dedicated to an α-Stirling Engine. The low efficiency of an α-Stirling Engine drives us to improve on its work characteristics in order to rise-up its efficiency [2]. The main way to achieve this is to improve the engine characteristics. There are a lot of mechanisms species that could be used to obtain a dwell movement function that is necessary to the compression cylinder. A bar mechanism could be more reliable than cam mechanism despite that the cam mechanism is more precise. The bar mechanism presented in this paper has seven bars but seems to be reliable enough for this application. There are other ways to improve the efficiency, to change the working gas from the cylinders. A good efficiency is obtained using a gas that has a high specific heat, like hydrogen or helium.
