Twelve cylinders. Forty-eight valves. Built to run.
The RUIFEIYA V12-180 compresses the architecture of a full automotive powerplant into a 1/4-scale, 180 cc working engine assembled from more than 300 components. Its four-stroke V12 layout combines DOHC cylinder heads, four valves per cylinder, triple carburettors and three-ring pistons.
Pressure-fed lubrication, external centrifugal water cooling and one-key electric start support genuine operation from 2,000 to 13,000 rpm, delivering the motion, sound and technical depth serious collectors expect.
RUIFEIYA / 1:4 WORKING V12
Twelve cylinders, engineered without shortcuts.
A finished working engine for collectors, engineering displays and ambitious large-scale vehicle or boat installations.
01 / ARCHITECTURE
More cylinders. More theatre.
A 180 cc V12, DOHC heads and 48 valves recreate the layered intake, exhaust and valvetrain complexity of a full-size performance engine.
02 / LUBRICATION
Pressure where it matters
Separate high- and low-pressure oil pumps feed moving parts and recover oil, while drilled crankshaft passages protect bearings during operation.
03 / OPERATION
Made for the starting ritual
Triple carburettors, electric starting and external water cooling support a 2,000–13,000 rpm operating range.
