A Real Working V12. Most engine models are designed to show what an engine looks like. The RUIFEIYA V12-180 is designed to demonstrate how a real multi-cylinder internal combustion engine actually works. Developed through years of refinement and assembled from more than 500 precision components, this engine recreates the mechanical architecture of a high-performance automotive V12 at 1/4 scale. Fuel delivery, ignition, lubrication, water cooling, valve timing and combustion work together as one integrated mechanical system. Start it, tune it and experience the synchronization of twelve cylinders, rotating timing components and a genuine four-stroke combustion cycle. For serious enthusiasts, the V12-180 delivers an experience that an electrically driven display engine simply cannot reproduce. LIMITED PRODUCTION 20 Units Only A Rare V12 Built for Serious Collectors The RUIFEIYA V12-180 is not a mass-market engine model. This release is strictly limited to 20 units. Each engine represents an unusually complex combination of precision machining, twelve-cylinder mechanical architecture, real gasoline combustion, dedicated lubrication, water cooling and electronic ignition. For enthusiasts looking for a working mechanical centerpiece rather than another static display model, the V12-180 offers a level of engineering presence that very few miniature engines can match. THE HEART OF THE MACHINE 180cc · 60° V12 Architecture At the center of the V12-180 is a genuine 60-degree twelve-cylinder configuration with a total displacement of 180cc — 15cc per cylinder. Each cylinder uses a 27 mm bore and 27 mm stroke, creating a compact square-engine geometry designed for high-speed operation. True 12-Cylinder Layout Twelve individual cylinders are arranged across two banks at a 60-degree angle, reproducing the iconic architecture of a performance V12. 13.7:1 Compression Ratio A high compression ratio combined with precision-machined combustion components creates an authentic high-performance engine architecture. 2,000–12,000 RPM The official operating specification spans approximately 2,000 to 12,000 RPM, creating a broad and dynamic operating range. Rated at 17 HP Despite its compact scale, the V12-180 is specified at 17 horsepower, placing it far beyond conventional desktop engine models. HIGH-PERFORMANCE VALVETRAIN DOHC · 48-Valve Cylinder Heads The V12-180 uses a Dual Overhead Camshaft (DOHC) valvetrain with four valves per cylinder for a total of 48 valves. This architecture brings the complexity and visual character of a performance automotive engine into miniature scale. Exposed timing belts and precision pulleys allow enthusiasts to observe one of the most important mechanical relationships in any four-stroke engine: synchronization between crankshaft position and valve timing. REAL FUEL DELIVERY Three Independent Carburetors Three independent carburetors manage fuel delivery across the twelve-cylinder engine. Unlike an electric demonstration model, the V12-180 requires real fuel supply and proper air-fuel mixture adjustment. The factory baseline for both the main and secondary carburetor needles is approximately 1.5 turns open, with fine adjustments made according to actual operating conditions. This tuning process is part of what makes the V12-180 a genuine mechanical enthusiast platform rather than a decorative display piece. ENGINEERED FOR REAL OPERATION Full-Circulation Dual-Pump Lubrication A high-performance combustion engine requires more than simply adding oil. The V12-180 features an independent high-pressure and low-pressure dual-pump lubrication system. The high-pressure system supplies lubricant to critical moving components such as the crankshaft, camshafts and connecting rods. Internal oil passages distribute lubrication throughout the engine while the low-pressure system returns oil to the external reservoir. This continuous circulation system helps reduce component wear and supports stable long-term operation. THERMAL MANAGEMENT External Centrifugal Water Cooling Twelve cylinders generate genuine operating heat. The V12-180 therefore uses an external centrifugal water pump with dedicated coolant passages to move heat away from the cylinder block. The cooling system is a functional requirement, not a cosmetic feature. A complete water-cooling circuit must be connected before the engine is operated. For adequate heat dissipation, the official operating instructions specify a radiator measuring at least 240 × 100 mm. CONTROLLED START-UP 3660 Brushless Electric Start Instead of relying on a traditional pull starter, the V12-180 uses a 3660 brushless motor electric starting system. Combined with its dedicated ignition electronics, temperature sensors and tachometer display, the system provides a significantly more sophisticated operating experience than a conventional miniature engine. BEFORE YOUR FIRST START What You Need to Operate the V12-180 The engine itself is supplied as a pre-assembled unit, but the V12-180 is a real fuel-powered internal combustion engine. Cooling, lubrication, fuel, ignition and electrical systems must be correctly prepared before operation. Fuel: 95#/98# pure gasoline Engine Oil: 5W-30 or 10W-40 fully synthetic four-stroke oil Oil Capacity: approximately 200 mL external oil supply Fuel Tank: 500 mL or larger recommended Cooling: water tank, radiator, coolant and water pump Starter System: 200A ESC with compatible 5S–6S battery CDI Ignition: 12V system using a compatible 3S battery Fuel Line: gasoline-resistant tubing Lubrication Hardware: oil reservoir, filter and oil cooler Important This is a high-precision gasoline-powered engine, not a plug-and-play electric display model.
