This is an external combustion engine that continuously burns the fuel, and the vaporized expanded hydrogen (or helium) acts as a motive gas to move the piston, and the expanded gas cools in a cold air chamber, and the cycle is repeated. The single-cylinder engine is the simplest of all engines, it has only one cylinder and is the basic form of the engine. This type of Stirling engine, known as the beta configuration, features just one cylinder with a hot end and a cool end. The working gas is transferred from one end of the cylinder to the other by a device called a displacer.\u003c\/p\u003e\n\u003cp\u003eThe simplified model of Stirling engine can be divided into two categories: ① hot and cold cylinder split type (Alpha-type) ② cold and hot cylinder integrated type (Beta-type).\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cstrong\u003eHow does a single cylinder Stirling engine work?\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003eStep 1: Most of the gas is located in the hot cylinder and is in large-area contact with the high temperature cylinder. The gas expands after being heated. Since the hot cylinder has reached the maximum volume and the cold cylinder is at the minimum volume, the gas rushes into the cold cylinder and drives the flywheel to rotate. similar to an isothermal expansion process.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eStep 2: After the heated gas rushes into the cold cylinder, it contacts with the low temperature cylinder in a large area to reduce the temperature. Due to the flywheel's moment of inertia, the hot cylinder is ready to start shrinking. It is similar to an isovolumetric exothermic process.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eStep 3: Most of the gas enters the cold cylinder. After sufficient cooling, the pressure begins to decrease. Combined with the rotational inertia factor of the flywheel, the gas is compressed in the cold cylinder. similar to an isothermal compression process.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eStep 4: The volume of the gas is the smallest at this time, and the gas in the hot cylinder expands after being heated. Due to the position of the crank rocker, the capacity of the cold cylinder is almost unchanged, and the capacity of the hot cylinder becomes larger, returning to the state of the first step. It is similar to an isovolumic endothermic process.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe above four stages are a cycle, which constitutes the complete working process of a single-cylinder Stirling engine. The multi-cylinder Stirling engine just connects several Stirling engines of different phases to the same set of flywheels, and there is not much difference in principle.\u003c\/p\u003e","products":[{"product_id":"stirling-engine-kit-miniature-balance-stirling-engine-model-toy-with-crystal-glass-bottom","title":"Stirling Engine Kit Miniature Balance Stirling Engine Model Toy With Crystal Glass Bottom","description":"\u003cp\u003e\u003cem\u003e\u003ciframe width=\"340\" height=\"320\" src=\"https:\/\/www.youtube.com\/embed\/ZG38DlsukFI\" frameborder=\"0\" allow=\"accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStirling Engine Kit Miniature Balance Stirling Engine Model Toy With Crystal Glass Bottom\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e.Excellent performance and beautiful appearance.\u003cbr\u003e.High quality, the cylinder is carefully processed from brass, with high precision and wear resistance.\u003cbr\u003e.Support plates, connecting rods, pistons, etc. are made of stainless steel, and the bottom plate is made of crystal glass, which is full of luxury.\u003cbr\u003e.The model as a whole is a material that does not rust.\u003cbr\u003e.The pursuit of the details, the overall fine grinding, touched very smooth, very metallic and modern technology, to achieve a dual combination of texture and beauty.\u003cbr\u003e.The Stirling engine is powered by the expansion of the gas and the compression of the cold.\u003cbr\u003e.95% alcohol (self-prepared) should be used in the operation.

It has two hot cylinders and can run stably for a long time with strong power. At the beginning of an outstroke, a valve in the head of the cylinder opens and admits a charge of burning gas and air, which is trapped by the closing of the valve and expands. Towards the end of the stroke the charge comes into contact with a water- or air-cooled part of the cylinder and is chilled, causing a sudden drop in pressure sufficient to suck the piston – which is open towards the crank – back on the return stroke. The valve opens again in time for the piston to expel the burnt gases before the next outstroke begins.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-family: Arial,Helvetica,sans-serif;\" data-mce-style=\"font-family: Arial,Helvetica,sans-serif;\" data-mce-fragment=\"1\"\u003e\u003cspan style=\"font-size: 14px;\" data-mce-style=\"font-size: 14px;\" data-mce-fragment=\"1\"\u003e\u003cstrong\u003eHow to Start and Run Vacuum Engine?\u003c\/strong\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-family: Arial,Helvetica,sans-serif;\" data-mce-style=\"font-family: Arial,Helvetica,sans-serif;\" data-mce-fragment=\"1\"\u003e\u003cspan style=\"font-size: 14px;\" data-mce-style=\"font-size: 14px;\" data-mce-fragment=\"1\"\u003e1.Placed the Stirling engine in a horizontal position, use your hand to toggle the flywheel to see if it is smooth.\u003cbr\u003e2. inject 95% alcohol fuel into the alcohol lamp, light the alcohol burner,dry the air in the cylinder to generate pneumatic power, and at the same time toggle the flywheel after 2 minutes to help start.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-family: Arial,Helvetica,sans-serif;\" data-mce-fragment=\"1\" data-mce-style=\"font-family: Arial,Helvetica,sans-serif;\"\u003e\u003cspan style=\"font-size: 14px;\" data-mce-fragment=\"1\" data-mce-style=\"font-size: 14px;\"\u003e\u003cstrong\u003eWhy You Choose it?\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cstrong\u003e.Sophisticated Craftsmanship\u003c\/strong\u003e: \u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-family: Arial,Helvetica,sans-serif;\" data-mce-fragment=\"1\" data-mce-style=\"font-family: Arial,Helvetica,sans-serif;\"\u003e\u003cspan style=\"font-size: 14px;\" data-mce-fragment=\"1\" data-mce-style=\"font-size: 14px;\"\u003eIt is made of all copper, imported heat insulation board, heat resistance and higher stability.
