Highly realistic V12 mechanical structure: The entire unit is crafted from over 500 precision parts, a 1\/4 scale replica of a real V12 engine. It features a 60° V-type layout, DOHC-48 valves, a high compression ratio of 13.7:1, and three-ring pistons to enhance cylinder sealing. During operation, the gears, belts, and pistons are dynamically visible, recreating the iconic deep, resonant sound of a V12 engine.\u003cbr\u003e2. High and Low Pressure Dual Oil Pump Circulation Lubrication for Durable Operation: Utilizing a high and low pressure dual oil pump system, the high-pressure oil pump supplies oil to the crankshaft and camshaft, with the camshaft receiving jet lubrication; the low-pressure oil pump recovers and recirculates the oil. The crankshaft has its own oil port, supplying oil via the main oil passage in the cylinder block, reducing component wear and malfunctions, and supporting long-term continuous operation.\u003cbr\u003e3. External Centrifugal Water Cooling for Efficient Temperature Control and Heat Dissipation: Equipped with an independent centrifugal water-cooling pump and enlarged intake and drainage channels, it quickly dissipates heat from the cylinder block, effectively suppressing overheating at high speeds. Whether for extended demonstration runs or RC installations, it maintains a stable engine operating temperature.\u003cbr\u003e4. Brushless One-Button Electric Start with Full Electronic Control Monitoring: A brushless motor enables one-button electric start. It features a V12-ECU, CDI high-voltage ignition system, oil and coolant temperature sensors, and a speed display; it uses a three-carburetor oil supply system and is compatible with 200A ESCs and 5-6S lithium batteries.\u003cbr\u003e5. Ample Power, Suitable for RC Car and Boat Modification: The powerful engine can drive 1\/4 scale cars, 1\/5 scale monster trucks, and large RC boat models, delivering realistic internal combustion engine power feedback and fully satisfying the needs of hardcore enthusiasts for modification, tuning, and testing.\u003cbr\u003e6. Multiple Values for Collection, Display, and Education: The dynamic operation creates a strong visual impact, suitable for display and collection in studios and showrooms. It can also be used as a teaching aid in schools and maker organizations, intuitively demonstrating the working principle of internal combustion engines, and is a high-end and unique gift for mechanical enthusiasts.\u003cbr\u003e7. Complete Package Included, Simplifying Tuning Preparation: The engine unit is pre-assembled, eliminating the need for self-assembly. It comes fully equipped with water-cooling components, sensors, ECU controller, tachometer, spark plugs, oil filter, and other accessories. Only a fuel tank, external oil tank, and power battery are required for tuning.\u003cbr\u003e8. ⚠️Warm Reminder: This product is a high-performance precision internal combustion engine model, intended only for users aged 18 and above with practical experience operating internal combustion engines; new engines require 25 hours of idling break-in; during the break-in period, it is strictly forbidden to violently increase the engine speed; operation must be carried out in a well-ventilated and open environment, and maintenance must be performed according to the instruction manual; non-professionals should not disassemble the engine themselves.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRecommended Age:\u003c\/strong\u003e 18+\u003cbr\u003e\u003cstrong\u003ePackaging: \u003c\/strong\u003eSuitcase\u003cbr\u003e\u003cstrong\u003ePack List:\u003c\/strong\u003e\u003cbr\u003eV12 Engine*1\u003cbr\u003eInlet Water Hose*1\u003cbr\u003eOutlet Water Hose*1\u003cbr\u003eOutlet Water Hose Elbow*1\u003cbr\u003eInlet Water Hose Elbow*1\u003cbr\u003eInlet Water Hose One-Way Valve*1\u003cbr\u003eRadiator*1\u003cbr\u003eRadiator Fan*2\u003cbr\u003eWater Grate*1\u003cbr\u003eOil Inlet Hose*1\u003cbr\u003eOil Outlet Hose*1\u003cbr\u003eOil Tank*1\u003cbr\u003eOil Filter*1\u003cbr\u003e200A ESC*1\u003cbr\u003eSpark Plugs*12\u003cbr\u003eHigh Voltage Coil*2\u003cbr\u003eIgnition Controller*1\u003cbr\u003eOil Temperature Sensor*1\u003cbr\u003eCoolant Sensor*1\u003cbr\u003eTachometer Display*1\u003cbr\u003eLimited Edition Metal Nameplate*1\u003cbr\u003eInstruction Manual*1\u003c\/p\u003e","brand":"enginediyshop","offers":[{"title":"Default Title","offer_id":53400359633036,"sku":"3746032","price":10999.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0548\/8377\/8700\/files\/44b13500-6eaa-4115-843c-991f92a65342.jpg?v=1787301279","url":"https:\/\/www.enginediyshop.com\/de-de\/products\/ruifeiya-v12-180cc-4-stroke-gasoline-engine-model-dohc-48-valve-water-cooled-engine-with-ecu-cdi-electric-start","provider":"enginediyshop","version":"1.0","type":"link"}
