TECHING DM13 Pre-Assembled Inline 4 Cylinder Metal Engine Model Limited Clearance
Hero Section: A Rare Opportunity to Own Industrial History
Step back to 1913, the year Jules Goux dominated the Indianapolis 500 with the revolutionary inline four-cylinder engine. The TECHING DM13-L4-P is a tribute to that golden era of mechanical engineering. Note: This is a special "Factory Display Edition." Unlike our standard DIY kits, this engine comes fully pre-assembled by our factory technicians. It is the perfect choice for collectors who want the stunning industrial aesthetic and mechanical motion immediately, without the 4-hour assembly time. With only 40 units remaining of this classic version, this is your final chance to own a piece of mechanical art at an unbeatable price.
Why Choose This "Factory Display" Edition?
- Instant Gratification (Pre-Assembled): Skip the complex assembly. This unit has been professionally assembled by the factory for display purposes. It is ready to run the moment you take it out of the box. Perfect for those who love mechanics but lack the time or patience for building.
- Unbeatable Value: Because these were used as display models or are the "Classic Version" stock, they are offered at a significant discount compared to the brand-new DIY kits. You get the same full-metal quality for a fraction of the price.
- Full Metal Luxury: There is no plastic here. The engine is crafted from CNC-machined aluminum alloy and stainless steel, finished with an anodic oxidation process. It feels cold, heavy, and premium to the touch—a true centerpiece for any executive desk.
- Limited Collector's Run: This is the classic version of the L4 engine. With production ceased and only 40 pieces left in the world, once they are gone, they are gone forever.
Technical Highlights: Engineering Transparency
- Visible Mechanics: The open-skeleton design allows you to see the internal combustion logic clearly. Watch the crankshaft rotate, the connecting rods push the pistons, and the valves open and close in perfect synchronization.
- Historical Accuracy: Based on the 1894 Maybach design and the 1913 racing engines, this model features a realistic overhead camshaft structure, demonstrating the evolution of automotive power.
- Electric Drive System: Powered by a built-in 500mAh lithium battery, the engine runs smoothly and quietly. It simulates the operation of a real engine without the noise, fumes, or need for flammable fuel.
- Precision Casting: Over 300 parts (already assembled) were created using precision casting and specialized abrasive tooling, ensuring that every gear mesh and piston stroke is smooth and reliable.

Important Tips from the Workshop
- Condition Note: As these are factory display/clearance units, the packaging may show minor signs of shelf wear, but the engine itself is fully functional and inspected.
- Charging: Please use a standard 5V USB charger (like a computer port or phone block). Do not use high-voltage "fast chargers" as they may damage the battery circuit.
- Maintenance: Although pre-assembled, the engine is mechanical. Keep it dust-free. A soft cloth is all you need to maintain its metallic shine.
