Hot Air Stirling Engine Motor Model Education Toy Electricity Power Generator

  
Material: SUJ Alloy Steel, 304 Stainless Steel, 6061 Aluminum Alloy, Brass and Bamboo. Ages: This hot air Stirling Engine Model Toy Kit Only Suitable for People Over 16 Years Old. This Stirling Engine Model Kit is two?

-type twin-cylinder double-piston Stirling engines: The? -type Stirling engine does not have a separate air distribution cylinder.

Since there are two independent and structurally identical sets of cylinders, one set generates heat while the other set performs cooling work, and both sets generate power. Due to their complete independence, the two sets of cylinders have a significant temperature difference. When the temperature on the heating side reaches 600 degrees Celsius, the temperature on the cooling side remains around 50 degrees Celsius after continuous operation for 20 minutes. This creates a temperature difference of over 500 degrees Celsius, which is sufficient for sustained power output and is a key feature of Stirling engine performance.

The connecting rods of the two sets of cylinders are not directly connected but rather linked through two gear systems with a gear ratio designed as 2:1. The crankshaft speed reaches 100 RPM while the flywheel with a diameter of 78mm and weighing 155g rotates at 200 RPM due to its powerful inertia, making the machine operation more stable. For single-cylinder diesel engines aiming to handle strong vibrations and achieve smooth operation, this design is adopted.

To improve the lifespan as much as possible for both cylinder walls and pistons, we use GCR15 bearing steel as raw material for cylinder liner and piston sleeve. After CNC machining, they undergo quenching treatment to increase hardness to between 58-62 HRC before being subjected to grinding treatment where precision can reach around ±.

While pistons perform reciprocating motion within cylinders, they also need to seal gases inside cylinders as effectively as possible; this is key in demonstrating precision in Stirling engines. Exquisite Craftsmanship: The base, bracket and 2 flywheels are made of 6061 aluminum alloy, high strength, weldability and corrosion resistance. 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; Axle joints connected with very high precision miniature bearings, stability without lubrication; The power and heat cylinder is made of brass and 304 stainless steel, service life is long. Heavy Duty & Stable : This engine is Much More Bigger than most of the Stirling engines you can find.

It's very heavy, 3.96 lb, so it can run stably on table. To achieve smoother operation along with reduced noise levels during machine operations, this Stirling engine model utilizes 14 precision bearings. This hot air steam motor engine model uses dynamic power cylinder measuring Ø20MM along side stainless steel heating tubes also totaling Ø20MM on either side ;the heating tube length on one side is noticeably longer than that on the cooling side.

This design is intended to achieve a better compression ratio. The biggest advantage of vertical cylinders is that the vertical pressure exerted by the piston on the cylinder wall can be minimized. This is also why many four-cylinder engines in household cars are designed vertically. This Stirling Engine Model Kit employ a separate design for cooling and heating cylinders, with stainless steel heat insulation plates used to isolate both sets of cylinders. The ability for Stirling engines to achieve greater temperature differences has been a primary consideration for designers.

EASY OPERATION & LONG LASTING: Fill the alcohol burner with your 95% alcohol (we recommend this fuel) and light it. Let the light burn the ended cylinder for about 20 seconds, then give the wheel a gently push, it will run like a charm.

COLLECTION & GIFT: When you don't play with it, it can be placed on your desktop or cabinet as a work of art. You can also give it as a gift to your relatives or friends. If you are a Stirling collector, it will be an indispensable collection. PRIORITY GIFT OPTION FOR MANY APPLICATIONS : It is an amazing and fantastic product at this price. Its elegant gift package makes it spruce up and presentable. It has a wide range of application as, great gift for Kids' science project, Physical/mechanical learning, teacher's Demo props on the class, birthday gift for friends, families, parents, kids, etc. Many of our customers come from school, colleague, etc. Exquisite Stirling Engine Model Kit x1. ONLY SUITABLE FOR PEOPLE OVER 16+. DON'T TOUCH THE SURFACE OF THE MACHINE DURING OPERATIONS TO AVOID BURNS. IF THE MACHINE DOES NOT WORK PROPERLY, DO NOT FORCEFULLY START IT.
