FourCylinder Precision Stirling Engine Model A mechanical demonstration built for clarity and longevity. This fourcylinder Stirling engine uses a synchronized multipiston arrangement to convert heat into mechanical motion and drive a small generator and LED light bulb. The model is designed for handson visualization of thermodynamic principles and for display by serious collectors. Key benefits Clear visualization of energy conversion: Watch heat applied from an alcohol lamp produce coordinated piston motion that powers the included generator and lights the LED bulb, making the entire process observable in real time. Ready to use: Fully preassembled for immediate operation. No tools or technical skills required to begin demonstrations. Robust construction: Major components are CNCmachined from stainless steel rather than stamped metal, improving resistance to wear, corrosion, and heat deformation for longterm use. Educational resource: Supplied with a detailed guide that explains the underlying physics, multicylinder mechanics, and design considerations that affect conversion efficiency. Reliable demonstration tool: Mechanical synchronization of four pistons provides a rare and intricate display of advanced thermodynamics suitable for teaching or collection. Function and compatibility Function: External combustion Stirling engine that converts heat into mechanical motion and electrical output through a small generator. Heat source compatibility: Designed to operate when heated with an alcohol lamp or similar lowtemperature heat source. Included accessories: Generator and LED light bulb included to demonstrate electrical output. Assembly: Delivered fully assembled for immediate demonstration. Typical use scenarios STEM classroom demonstration: Use to illustrate heat engines, thermodynamic cycles, and energy conversion with a visible, working model. Laboratory or lecture aid: Integrate into physics lessons to show multicylinder synchronization, efficiency factors, and mechanical timing. Collector or desktop display: Provide a precise, mechanical centerpiece that demonstrates engineering craftsmanship and motion. Materials and performance CNCmachined stainless steel components for durability and dimensional accuracy. Multipiston, fourcylinder arrangement for smooth, measurable motion.
