Cupid Arrow Hot Air Stirling Engine Model Educational Electricity Generator STEM Toy

The engine was invented by London’s pastor Robert Stirling in 1816, so it is named the “Stirling Engine”. The Stirling Engine is unique because its theoretical efficiency is almost equal to the theoretical maximum efficiency, known as the Carnot Efficiency. The Stirling Engine is made up of a sealed cylinder with a piston inside. It works by heating the gas (often air, hydrogen or helium) in one end of the cylinder, forcing the piston to move. Then the gas cools at the other end of the cylinder by means of a heat sink, forcing the piston to move back as the gas rushes back to its former position. The engine can only start with a brief boost of energy, after which this cycle will continue providing energy until the heat source dissipates. To start your engine follow these steps carefully: 1. Place the engine model on a flat surface in a horizontal position. 2. Secondly, gently turn the wheel to check whether it has a smooth rotation. The piston’s weight will hold back the rotation somewhat, but this is to be expected. If there is real resistance and the wheel cannot rotate, then there is a problem. Make sure that there is nothing stuck within the wheel that would stop it rotating. 3. Next, twist the wick into the metal ring. Thread it through until there is 1 cm on top. You may need to use this to help you push it through. 4. Next, use the syringe to suck up a little alcohol and pour it into the flask. 5. Put the wick in the flask 6. Put the flask under the cylinder. The wick should be nearly touching the cylinder. 7. Light the wick 8. After 20 seconds, spin the wheel. The engine will not turn on by itself; it requires a little push to get started. Maintenance plans (if the model is not running very well) 1. Check if there is enough alcohol in the alcohol lamp. 2. Check if the small and big wheel jackscrews loose or not. 3. Too high temperature in the air cylinder because of the continuous heating for a period of time will affect the performance of the product. 4. Check the valve position: the highest position of the flapper valve (2) is to cover one fourth of the valve port. 5. Check if the angle is correct or not: when the piston (7) lies in the innermost of the air cylinder, the small jackscrew (3) hole should be just facing the positioning port (6). If the position is wrong, please loosen the jackscrew; then tightly fix the jackscrew in the correct position.
