This is an external combustion engine in which the fuel is burned continuously, and the piston is moved by the expansion of air (or helium or hydrogen) as a medium, and the expansion gas is cooled in the cold chamber, and the cycle is repeated. Only a small alcohol lamp, you can make it fast rotation and generate strong power.As the external combustion engine, it avoid the explosion risk when traditional internal combustion engine working, in order to achieve a high efficiency, low noise, low pollution and low operating costs. The biggest advantage of the external combustion engine is that the output and efficiency are not influenced by altitude, very suitable for high altitude areas.Instructions: Put the engine model on the horizontal position, toggle the flywheel to see if it is smooth, if there is a strong sense of raw astringent, check the connection rod, whether the cylinder has oil and dust, and if so, please use toilet paper to erase. Toggle the flywheel feel pressure rebound within the cylinder body is a normal phenomenon, the cylinder is sealed.The packing bag of alcohol lamp cotton wear into the metal cap lamp. Please go to the pharmacy to buy 95% purity alcohol, anhydrous industrial alcohol better. Fill the alcohol lamp to less than two-thirds. Alcohol lamp to the alcohol lamp, at the premise of ensuring safety, ignite the alcohol lamp about 2 minutes after the flywheel, until the flywheel automatic operation so far, the whole process of heating, hands may not touch.Led lights can be directly into the generator output interface, if not inserted, the exchange can be positive and negative, led a long foot for the cathode.Safe End Procedure:After use, allow the engine to cool naturally.After the engine cools naturally, keep the engine out of the reach of small children.Children in adults under the care of the use of the engine, so as not to burn or break accidentally broken bar injury.Note:Do not touch the baked test tube and the metal connected to it, so as not to burn.Long time light alcohol lamp, alcohol lamp can not easily touch, so as not to burn.Suitable for more than 8 years of age, 8 years of age need to operate under the guardianship of parents.When heating, do not touch the tube of alcohol lamp tube, wick combustion will produce moisture, if touched, may lead to tube cracking.Both ends of the connecting rod joint activities need to add regular oil lubrication, the piston can not refuel, otherwise it will not work the resistance.Name: Stirling Engine ModelModel: 479857Flywheel Diameter: about 60mmTransmission Wheel Diameter: about 25mmPower Cylinder Bore: about 12.5mmPiston Stroke: about 13mmGenerating Voltage: 3-5vSuitable Age: 8 years old and aboveExperiment Type: physicalcolour: silverMaterial: metalPackage Contents:1 x Engine Motor ModelOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
