Free-Piston Stirling Engine Technologies and Models: A Review

The Stirling engine is an alternative solution to produce cleaner energy in order to achieve the reduction of the fossil fuel consumption and the CO<sub>2</sub> emissions. It comprises an external combustion engine that can convert any external heat source into mechanical power, through...
