5.9 Mini Hot Air Stirling Engine Motor Model Science Education Toy Kit New
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 Do not wear high-speed ultra-long-running Heating cylinder of quartz glass High temperature resistance and low temperature resistance. Package included: 1 x Stirling engine model. Description: Name:Stirling Engine Model Material:quartz glass+galvanized aluminum Color:silver Temperature range:-30? Size:15580130mm Note: - There will be the operation of steam, when steam too much time, the engine will stop working, inside and outside the needle often set aside to reduce friction - Do not rotate the nut too tightly, otherwise the glass is broken, if the piston is cracked, can be bonded with glue. The alcohol lamp wick do not touch the glass, do not get too tight ring - Pulling the piston connecting rod can not force the front end, because the front end is easy to breakpare parts piston. This is traditionally known as an external combustion engine in contrast to an internal combustion engine where the heat input is by combustion of a fuel within the body of the working fluid. Unlike the steam engine's use of water in both its liquid and gaseous phases as the working fluid, the Stirling engine encloses a fixed quantity of permanently gaseous fluid such as air or helium. As in all heat engines, the general cycle consists of compressing cool gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cycle.
