Analysis of Sweep Volume Effect on the Output Power and Velocity of a Gamma-Type Stirling Engine with Slider-Crank Mechanism Features

The Stirling engine is an external combustion engine that can generate electricity without any pollution; in the other words, it can generate energy from renewable energy sources such as solar energy. In this research, the gamma-type Stirling engine with slider-crank mechanism with three different sweep volume ratios ۱, ۱.۵, and ۲ are manufactured and compared. It is observed that in the engine when the sweep volume ratio is ۲, the result is better and more than the remaining types; Another conclusion from this comparison is that a lower temperature difference is required for a larger sweep volume ratio. So, the engine when the sweep volume ratio is ۲, a lower temperature difference required for reaching a higher and better output is required.
