Stirling Engine Motor Model in gold color, constructed from zinc alloy and stainless steel. Designed as a handson physical experiment model, it uses a glass tube and a glass alcohol lamp for clear, direct observation of the piston and wheel motion. Fuel required is 95 percent alcohol. Package includes one Stirling engine motor model. Key benefits Clear visualization: Glass tube and glass alcohol lamp let students and hobbyists watch piston motion and heat transfer in real time for effective demonstration and study. Simple operation: Replenish with 95 percent alcohol, ignite the combustor, allow the flame to heat the cylinder end for 60 to 120 seconds, then gently rotate the wheel to start motion. Stable, reliable setup: Four antiskid pads at the base provide steady placement and reduce unwanted movement during operation. Durable materials: Zinc alloy and stainless steel construction offer a solid build and consistent mechanical performance. Lownoise operation: Designed for smooth rotation and modest sound levels during use. Features and specifications Item type: Stirling engine motor model Materials: Zinc alloy and stainless steel with glass tube and glass alcohol lamp assembly Fuel: 95 percent alcohol Color: Gold Package contents: 1 x Stirling engine motor model Practical use scenarios Classroom demonstration: Use as a visual aid in physics lessons to demonstrate thermodynamic principles, piston motion, and basic engine cycles. Science fair or lab display: Present a functional, compact example of external combustion engines and heattomotion conversion. Desk or hobby display: Operate as an educational desktop model for hobbyists who enjoy mechanical models and smallscale thermal engines. Operation notes Use only 95 percent alcohol as the fuel source. After extended operation, replenish the combustor with alcohol before relighting. Ignite and let the flame heat the cylinder end for 60 to 120 seconds, then gently start the wheel by hand to initiate continuous motion. Place the model on a stable, flat surface to maximize performance and stability. This Stirling engine motor model combines visible engineering action, simple fueling and startup, and a stable mounting base for effective demonstrations and handson learning.
