Evaluation of displacement - time characteristics of stirling engine drive mechanisms - II

The relative merits of the mechanical configurations tried out so far in Stirling prime movers is examined based on isothermal analysis taking into account dead volume. Single and double acting cases are considered. It is concluded that the modified Rhombic configuration proposed in the first part, is superior to the conventional Rhombic and Slider crank configurations, in single and double acting modes. Further investigations on frictional losses and transient effects are necessary in making a final choice of the drive con figuration for implementing the Stirling cycle.
