The performance characteristics of the low power beta type Stirling engine were determined by gas exchange in this research, and the results were compared and presented by graphics. The performance tests of the Stirling engine heated by using the thermal specification of the sun were realized as 673 K, 773 K, and 873 K for the heater temperatures. The charge pressure was increased from 100 kPa up to 400 kPa with the ranges of 100 kPa. The maximum power was calculated by taking the frequency of crankshaft 10, 30, 50, and 60. Also, the electrical power increase was provided by raising the temperature difference between the hot edge of the displacer and the cooler temperature.
