Product Introduction:
For any serious stationary engine enthusiast, the year 2026 is undoubtedly an important date to mark in their diary. Based on the suggestions of numerous antique engine model collectors, restorers, and builders, and in our unique way of paying tribute to the classic industrial machinery of 100 years ago, we have launched this miniature scale model engine. Its history began with the sale of the first engine in 1926 and continued until production ceased in 1964, with over 250,000 units produced during that time. This groundbreaking research covers significant changes and improvements to this scaled-down engine, encompassing areas such as the fuel tank, mechanical ignition system, flywheel, and exhaust system, and features the first use of a 16mm bore metal piston ring. Interestingly, many stationary engine enthusiasts worldwide began their collections with this very engine – including ourselves – and this seemingly ordinary single-cylinder engine is indeed extraordinary! The restoration and maintenance of these engines bring endless joy to enthusiasts of all ages. Many young people learn the principles of internal combustion engines through hands-on experience, often using this engine as a stepping stone to larger and more professional mechanical fields. To the untrained eye, all such engines may seem similar, but in reality, they are vastly different – something every enthusiast knows well.

Product Features:
1. A Century of Tribute - Classic Stationary Engine: This engine was the "entry point" for countless stationary engine enthusiasts. This model is built with a centennial anniversary theme, possessing both historical value and collectible significance.

2. Truly Operable - Convenient and User-Friendly: No complex assembly required, equipped with a mechanical ignition system, supporting manual or electric drill starting. A sturdy solid wood base ensures smooth operation, allowing both beginners and experienced users to experience the operation of a real four-stroke engine in minutes.

3. Metal Construction - Retro Craftsmanship and Texture: The main body uses precision-machined metal parts, providing a realistic weight and mechanical feel. The retro green coating enhances the visual style and provides excellent anti-oxidation properties, suitable for long-term display and repeated operation.

4. Display-Grade Collectible - A Conversation Starter: Whether displayed in a study, workshop, office, or display case, it will quickly attract attention. It can be operated and played with, or displayed statically, making it an ideal gift for mechanics, model collectors, and history enthusiasts.

5. Observation and Play - Science Education: More than just a retro ornament, it's also a visual "industrial science education tool." By observing the working principles of the stationary engine, one can clearly understand the power logic and mechanical structure of early internal combustion engines, suitable for cultivating mechanical interest in young people and satisfying the nostalgic exploration needs of adults.
