Explore the fascinating mechanics of combustion with this meticulously crafted Vacuum Engine Model, designed to demonstrate the principles of internal and external combustion engines in an engaging and educational way. Utilizing the inertia of the flywheel to drive the piston, this model creates a vacuum inside the cylinder that draws in flame for combustion, showcasing the cycle of negative pressure and piston movement with clear, visible valve and piston action. Key Features: · Educational Vacuum Engine Principle: Demonstrates how the flywheel’s inertia moves the piston, lowering air pressure in the cylinder, drawing in flame, and maintaining continuous operation through vacuum-generated negative pressure. · Fully Assembled & Easy to Operate: Ready to use out of the box—simply ignite the alcohol burner and flip the flywheel until the engine runs autonomously, with no water required. · Transparent Mechanical Movement: Clearly displays the motion of the valve and piston, providing a hands-on learning experience ideal for students, educators, and researchers studying combustion engine mechanics. · Premium Build Quality: Crafted from fine polished stainless steel with a solid wood base, durable copper axles, and an all-metal hot gas cylinder and alcohol burner, complemented by a heat-resistant wick for long-lasting performance. · Compact & Portable Design: With a base plate size of 15 x 7 cm and lightweight construction (282g), this model is easy to handle and store, perfect for classroom demonstrations or personal study. · Complete Educational Kit: Includes the engine model, alcohol burner, bottle, three wrenches for adjustments, and an English user manual to guide setup and operation. Specifications: · Model: QX-ZK-01 · Base Plate Size: 15 x 7 cm (5.9 x 2.7 inches) · Item Weight: 282g (9.9 oz) · Package Size: 20.5 x 12 x 11.2 cm (8.1 x 4.7 x 4.4 inches) · Package Weight: 437g (15.4 oz) Package Includes: · 1 x Vacuum Engine Model · 1 x Bottle · 3 x Wrenches · 1 x Alcohol Burner · 1 x User Manual (English) Note: Alcohol fuel is not included.
