With a visible adjustable-flow main oil cup, a new-style carburetor, and a resonance exhaust pipe. The engine has a practical power output because the 2 enormous flywheels are perfectly balanced and equipped with a spring-loaded ball and a split widen pulley. A one-of-a-kind \"fast-slow switch gear\" has been specially built to fulfill the requirements of engine speed switching at super-slow speeds or high speeds for power output, providing users with increased playability and operational experience. In terms of craftsmanship, the entire model is treated with electrophoretic surface treatment in red, and the main components (body, flywheel, connecting rod, etc.) are cast in 304 stainless steel. All assembly surfaces are CNC precision processed, and the crankshaft is made of high-carbon steel and hardened. This is not only a playable engine model but also a highly collectible mechanical artwork.\u003c\/span\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\u003cspan style=\"font-size: 14px;\" data-mce-fragment=\"1\" data-mce-style=\"font-size: 14px;\"\u003e\u003cspan style=\"font-family: Arial,Helvetica,sans-serif;\" data-mce-fragment=\"1\" data-mce-style=\"font-family: Arial,Helvetica,sans-serif;\"\u003e.Notes: the RETROL HM-01 engine typically includes the engine itself.

One cylinder generates heat, while the other cools, resulting in a significant temperature difference that serves as a continuous power source. With 20mm power cylinders and stainless steel heating tubes on both sides, the engine achieves optimal compression ratios.\u003cbr data-mce-fragment=\"1\"\u003eThe connecting rods of the two cylinders are not directly linked but connected through a gear system with a designed gear ratio of 2:1. Running at 1000r\/min, the crankshaft and a powerful 78mm, 155g flywheel at 2000r\/min ensure stable operation. The engine incorporates 14 precision bearings for smooth and quiet operation. To enhance the lifespan of cylinders and pistons, GCR15 bearing steel is used, processed through CNC machining, quenching to increase hardness to 58-62HRC, and precision grinding to achieve an accuracy of ±0.005mm. The large-sized flywheel, twin cylinders, twin pistons, dual gears, brass connecting rods, crankshaft, and dual 10mm aluminum alloy supports contribute to a compact yet robust engine measuring 200138125mm and weighing 1.8kg.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eSpecifications:\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e.Material: Stainless Steel + Brass + Aluminum Alloy\u003cbr data-mce-fragment=\"1\"\u003e.Brand: ENJOMOR\u003cbr data-mce-fragment=\"1\"\u003e.Model: Alpha-Type Twin-Cylinder Twin-Piston Stirling Engine Model\u003cbr data-mce-fragment=\"1\"\u003e.Item Number: M20-W-01\u003cbr data-mce-fragment=\"1\"\u003e.Engine Form: Assembled Version\u003cbr data-mce-fragment=\"1\"\u003e.Heating Replacement Cylinder Inner Diameter: 20mm\u003cbr data-mce-fragment=\"1\"\u003e.Power Piston Diameter: 20mm\u003cbr data-mce-fragment=\"1\"\u003e.Piston Stroke: 20mm\u003cbr data-mce-fragment=\"1\"\u003e.Flywheel Diameter: 78mm\u003cbr data-mce-fragment=\"1\"\u003e.Pulley Diameter: 20mm\u003cbr data-mce-fragment=\"1\"\u003e.Total Bearings: 14\u003cbr data-mce-fragment=\"1\"\u003e.Start Method: Manual Start\u003cbr data-mce-fragment=\"1\"\u003e.Product Weight: 1816g\u003cbr data-mce-fragment=\"1\"\u003e.Product Dimensions: 20 x 13.8 x 12.5cm\u003cbr data-mce-fragment=\"1\"\u003e.Package Dimensions: 23 x 13 x 16cm\u003cbr data-mce-fragment=\"1\"\u003e.Package Weight: 2016g\u003cbr data-mce-fragment=\"1\"\u003e.Paking: Box\u003cbr data-mce-fragment=\"1\"\u003e.Ages: 16+\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Stirlingkit","offers":[{"title":"Default Title","offer_id":45609518891221,"sku":"3536302","price":176.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0134\/7446\/3808\/files\/stirlingkit-enjomor-alpha-type-stirling-engine-twin-cylinder-twin-piston-ec-engine-model_7.jpg?v=1705457057"},{"product_id":"14-engine-crankshaft-for-retrol-hm-01-hit-and-miss-engine-model","title":"#14 Engine Crankshaft for RETROL HM-01 HIT AND MISS Engine Model","description":"\u003cp\u003e\u003cspan style=\"font-size: 14px;\"\u003e\u003cspan style=\"font-family: Arial,Helvetica,sans-serif;\"\u003e\u003cstrong\u003e#14 New Engine Crankshaft for RETROL HM-01 HIT AND MISS Engine Model\u003cbr\u003e\u003cbr\u003eFeatures:\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e.This crankshaft is specifically designed for the RETROL HM-01 Hit-and-Miss engine model.

What needs to be emphasized is that engine production is far different from ordinary product manufacturing—it relies on multiple sophisticated and complex production lines with extremely strict production standards and processes. For this exclusive anniversary batch, the raw materials we prepared are only sufficient for 100 units of production. Though we actually produce a small quantity more than 100 units in the manufacturing process, every single unit has to go through rigorous quality testing afterwards. Inevitable material scrappage and unqualified products from the testing lead to our final available stock being exactly 100 units.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eOnce this limited batch is sold out, a re-stock will require waiting \u003cstrong\u003eanother 60 days\u003c\/strong\u003e for a brand-new production run, and the engine production cycle is quite long due to its complicated manufacturing requirements. This limited 100-unit production is also a special tribute to our precious 100th anniversary celebration.
