In this study, a V-type Stirling engine with 163 cc total swept volume was designed and manufactured. Air was used as working fluid. Performance tests were conducted at the range of 1-3 bar charge pressure and within the range of hot source temperature 700-1050 °C. Experimental results are given. Variation of engine power and torque with hot source temperature at various air charge pressure are tested. Also variation of engine torque with engine speed for different air charge pressure are tested. According to experimental analysis, the maximum engine power was obtained as 21.334 W at 1050 ˚C hot source temperature and 1.5 bars charge pressure

• engine will improve as depend on high temperature resistant material technology.

• In the present study, a V-type Stirling engine with 163 cc total swept volume was manufactured and performance tests were conducted at various charge pressures and various hot source temperatures. The maximum engine power was obtained as 21.334 W at 513 rpm engine speed and 1050 ˚C hot source temperature. The engine power and torque were increased with the increase of charge pressure and heat source temperature. The engine power was decreased due to leakage problems after a certain charge pressure.
• The factors that effect the Stirling motor performance and efficiency are the heat capacity of the working material, friction, mechanical losses and most importantly leakage problems. Efficiency calculations could not be established due to some mechanical and leakage problems. These calculations are planned to be made by working with higher heat capacity fluids like nitrogen, helium and hydrogen as soon as these problems are overcome.
• Turkey is an agricultural country with high solar energy potential. An electrical oven was used in the system for the beginning but solar energy with parabolic reflectors is aimed to be used for further studies.
