A method for evaluation of power loss of the simple action type stirling engine due to piston leakage


The effectiveness of the expanding gas in converting its pressure energy into mechanical work clearly depends on power piston being well sealed in the cylinder in which it moves. The Schmidt ideal isotermal analysis of a working cycle of the Stirling engine was used in order to determine this dependence. As a result the approximate formulae for the leakage and for the power loss have been derived and are presented.
