ENJOMOR M20-TZ-01 Rhombic Drive Stirling Engine Model External Combustion Gift
Hero Section: The Geometry of Power
Step away from conventional engine designs and witness the elegance of the Rhombic Drive. The ENJOMOR M20-TZ-01 isn't just a Stirling engine; it is a kinetic sculpture that utilizes a rare, coaxial gear mechanism to achieve perfect balance and efficiency. Invented by Philips for high-tech applications, the Rhombic Drive eliminates side loads on the piston, resulting in smoother operation and less wear. This model brings that advanced engineering to your desktop in a stunning display of brass, steel, and aluminum.
Why Choose the ENJOMOR Rhombic Engine?
- Rare Rhombic Drive Mechanism: This is the star feature. Unlike standard crank engines, this model uses a complex linkage of gears and dual connecting rods to drive the pistons in a perfect vertical line. It’s a mesmerizing mechanical dance that is rarely seen in model form.
- Coaxial Cylinder Integration: The design cleverly integrates the power piston and the displacer piston within a single 20mm cylinder axis. This compact, high-tech layout maximizes thermal efficiency and minimizes dead volume.
- Industrial-Grade Durability: We use GCR15 bearing steel for the cylinder liners and piston sleeves, hardened and precision-ground. This ensures the engine maintains high compression and runs reliably for years, far outlasting cheaper models.
- Visual & Educational Value: The open architecture allows you to see the synchronized brass gears and the unique rhombic linkage in action. It is arguably the best way to demonstrate advanced kinematic principles to students or fellow engineers.
Technical Highlights: Engineering Excellence
- Optimized Heat Exchange: The redesigned heat exchange piston and 304 stainless steel heating tube work together to maximize the temperature differential, providing sustained, powerful output.
- Precision Gear Synchronization: Brass gears ensure the two crankshafts rotate in perfect counter-rotation, balancing the engine's momentum and reducing vibration to near zero.
- High-Inertia Flywheel: A large 78mm flywheel stores kinetic energy, smoothing out the power pulses and allowing the engine to run at a steady, hypnotic rhythm.
- 8 Precision Bearings: To support the complex linkage, the engine utilizes 8 high-quality bearings, ensuring friction is kept to an absolute minimum.

Usage Scenario: The Engineer’s Masterpiece
It’s a quiet evening. You place the heavy, solid engine on your desk. You light the alcohol lamp and wait for the stainless steel head to glow. With a gentle push, the flywheels begin to spin. The brass gears mesh silently, and the rhombic linkage expands and contracts like a breathing lung. It’s a moment of pure mechanical harmony—a perfect blend of history, physics, and art.
Important Tips from the Workshop
- Fuel Requirement: Use 95% purity alcohol. Lower grades contain water and will not generate enough heat to drive the high-compression rhombic mechanism efficiently.
- Pre-Heating: Allow the flame to heat the cylinder for about 60 seconds before starting. The internal air needs to expand significantly to overcome the initial inertia.
- Do Not Lubricate: The GCR15 pistons are designed for a precision dry fit. Never oil the pistons or cylinder. Oil will carbonize and seize the engine.
- Safety: The heating tube gets extremely hot. Do not touch it during operation or immediately after.
