Color M14 V4 Stirling Engine Model A precisionbuilt, allmetal Stirling engine model designed for demonstration, experimentation, and display. Constructed from alloy steel, aluminium alloy, and brass with a polished finish, this V4 engine shows mechanical principles while providing a usable generator output for small electrical experiments. Key benefits Solid construction for lasting use: alloy steel, aluminium alloy, and brass components provide rigidity and wear resistance for repeated demonstrations. Clear demonstration of external combustion engine principles: the fourcylinder V4 layout, defined piston stroke, and visible flywheel make motion and timing easy to observe. Builtin generator and motor support: the included generator with a power output interface and an additional motor with external wiring let you measure output, connect LEDs, or extend the setup for DIY projects. Ready to run with simple assembly: assemble the quartz glass parts, fill the boiler with water, and light the four metal alcohol burners to start the engine without complex tuning. Features and specifications Cylinder configuration: V4 with four 16 mm cylinders and 16 mm piston stroke. Flywheel diameter: 54 mm for stable rotational motion. Electrical output: produces approximately 4 to 9 V suitable for lighting LEDs and powering small demonstrative loads. Materials: alloy steel, aluminium alloy, brass with a polished finish. Product size: 27 x 16.5 x 16 cm. Product weight: 2690 g. Package dimensions: 23 x 13 x 16 cm. Package weight: 2870 g. Color: M14. Packing: carton box. What is included 1 x Stirling engine model (V4) 4 x metal alcohol burners Generator with power output interface Additional motor with external wiring Quartz glass parts to assemble as shown Practical uses and applications Classroom and lab demonstrations: show thermodynamic cycles, conversion of heat to mechanical motion, and basic electrical generation using a compact, visible mechanism. STEM and hobby projects: use the generator output and external motor wiring for experiments, data collection, or to drive small indicators and LEDs. Desk display and mechanical education: a working mechanical model for technicians, students, and collectors who want to study movement, timing, and mechanical linkages. Operation notes Assembly requires fitting the quartz glass components and adding water to the boiler per the included instructions. Ignite the provided metal alcohol burners to start the engine; adjust burner placement and heat input for consistent operation. Use the generator output interface or the external motor wiring to connect LEDs or small loads for testing and demonstration. This Stirling engine model combines durable metal construction, a visible V4 cylinder mechanism, and integrated electrical output to support handson learning, experimental setups, and functional display applications.
