A Stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gas the working fluid at different temperature levels such that there is a net conversion of heat energy to mechanical work.The engine is like a steam engine in that all of the engine's heat flows in and out through the engine wall. - Description: Speed:1300 to 1500 RPM; - Features: Using mold steel manufacturing solid and firm; Flywheel fine milling texture and beauty double combination; Rod made ​​of stainless steel manufacturing; Dynamic link sets of aluminum alloy cylinder power cylinder and the power piston is SUJ2 material fine grinding surface of special treatment high hardness. Do not wear high-speed ultra-long-running; Heating cylinder of quartz glass.
