Product Information:
Looking for a running V12 engine model with real mechanical operation? The RUIFEIYA V12-180 combines 180cc displacement, 48-stem DOHC construction, water cooling, dual-pump lubrication, brushless electric start and electronic monitoring for RC applications, workshops and mechanical demonstrations.
Realistic 1/4 Scale V12 Engine Structure:
Built from 500+ precision components, the V12-180 features a 60° V12 layout, DOHC stem train, 48 stems, 13.7:1 pressure ratio and three-ring pistons. During operation, the pistons, gears and timing components move visibly to demonstrate the character of a working V12 engine.
Dual-Pump Lubrication System:
High- and low-pressure oil pumps work together to circulate engine oil through key components. The crankshaft incorporates oil passages, while the camshaft receives dedicated lubrication, supporting consistent oil circulation during extended running sessions.
External Centrifugal Water Cooling:
An independent centrifugal water pump and enlarged external water passages help transfer heat far from the cylinder block. The water-cooling system supports stable operating temperatures during demonstrations, testing, and compatible RC vehicle or boat applications.
Brushless Electric Start and Electronic Monitoring:
A 3660 brushless motor provides one-button electric starting. The system includes a V12 ECU, CDI high-voltage ignition controller, oil and coolant temperature sensors, and an RPM display. Three independent carburetors provide fuel delivery, with a 200A ESC and 5–6S lithium battery recommended.
Pre-Assembled Performance Engine for RC and Display:
The engine arrives pre-assembled with cooling components, sensors, ECU, RPM display, spark plugs, oil filter, and related components. Its 17 HP output is designed for compatible 1/4 and 1/5 RC vehicles and large RC boats, while the running mechanism also makes it suitable for workshop displays and mechanical demonstrations.

RUIFEIYA V12-180 is a pre-assembled V12 engine model developed over six years and constructed from more than 500 precision components. At 1/4 scale, it presents the complete structure of a high-performance V12 internal combustion engine. The engine arrives pre-assembled, eliminating the need for DIY assembly.
During operation, the pistons, timing mechanism and exhaust manifolds move in coordination, accompanied by the characteristic mechanical sound of a V12 engine. The system incorporates dual-pump lubrication, external centrifugal water cooling and one-button brushless electric starting to support extended operation.
The engine can serve as a high-end mechanical display model and can provide power for compatible 1/4 and 1/5-scale RC vehicles and boats. It can also be used for mechanical engineering demonstrations and internal-combustion-engine education.
Important Operating Notice: This is a high-performance precision internal-combustion-engine model intended only for users aged 18 and above with practical internal-combustion-engine operating experience. A new engine requires approximately 25 hours of idle break-in. Avoid high-RPM operation during the break-in period. Operate only in a well-ventilated, open environment and follow the instruction manual for maintenance and servicing. Non-professional users should not disassemble the engine.

Inheriting the engineering heritage of high-performance racing, the V12-180 features a dedicated four-valve configuration for each cylinder, precisely driven by a Dual Overhead Camshaft (DOHC) system. Its 48-valve architecture maximizes intake and exhaust efficiency, optimizes gas exchange cycles, and delivers faster, more precise response throughout the entire power range, while showcasing the distinctive mechanical beauty of a true high-performance V12 engine.
Dual-Pump Full-Circulation Lubrication System
High-Pressure Lubrication Pump: Precisely delivers lubricating oil to critical moving components such as the crankshaft, camshaft, and connecting rods. The internal oil passages within the crankshaft, combined with the main oil gallery in the engine block, ensure comprehensive lubrication throughout the entire system.
Low-Pressure Scavenge Pump: Responsible for recovering and returning oil back to the reservoir, creating a fully automatic closed-loop lubrication system.
This design effectively reduces component wear, minimizes the frequency of failures, and significantly extends maintenance intervals for long-term, stable operation.
High-Compression Three-Ring Piston Design
Engineered to withstand intense thermal loads, the connecting rod and piston assemblies feature a true automotive-grade three-ring layout (two precision gas compression rings and one dedicated oil control ring). This ensures immaculate cylinder sealing, minimizes blow-by, and stabilizes power output at high revs.
External Centrifugal Water Cooling
An independent centrifugal water pump and enlarged external water passages help transfer heat far from the cylinder block. The water-cooling system supports stable operating temperatures during demonstrations, testing, and compatible RC vehicle or boat applications.
Brushless Electric Start and Electronic Monitoring
Powered by a 3660 high-torque brushless motor, the V12-180 delivers a convenient and reliable one-key electric start experience, eliminating the hassle of traditional pull-start systems. The three independent carburetors precisely regulate fuel delivery, ensuring efficient atomization, stable combustion, and maximum V12 performance.
