V4 4-Cylinder Parallel Stirling Engine Kit Micro External Combustion Engine Model
★MOST POWERFUL: one of the BEST and most powerful Stirling engines on the market. Once this engine runs, you will be wowed. People love the sound and the power it reveals. It runs at speed up to 1300 to 1500 RPM and will light up the multicolor LED on the generator.
★HEAVY&STABLE: this egine is MUCH MORE BIGGER than most of the stirling engines you can find. It's very heavy, 6.7lb, so it can run stably on table.
★ROBUST&FINE CRAFTED: key parts use SUJ2 alloy steel/bearing steel with tolerance up to 0.002mm; with stainless steel hot cylinders; 4-Cylinder engine equips 16mm power cylinders/16mm stroke power pistons/20mm hot cylinders.
★WIDE APPLICATIONS: people bought it for kids' science project, physics/mechanics learning, demonstration on class, etc. It's a well-designed and crafted mechanical toy; great to display basic principle of external combustion engines; fantastic gift for people you love.
This engine will be driven by the lamp to a speed around 1300-1500 RPM. Kinetic energy generated will be transmitted to the little generator and then light up the bulb on it.
The power cylinder and piston of the engine are made by fine milled SUJ2 alloy steel with 0.005mm tolerance; the rod to the displacer piston employs fine milled bearing steel with 0.002mm tolerance.
It is assembled and will run within 5 minutes after opening the package provided you have a bottle of alcohol(purity >= 95%) by your side.
