RCV Small UAV Engines
Easy to calibrate. High power-to-weight ratio. Minimal carbonization.
RCV Rotary Valve Engines are 4-stroke single-, twin- and four-cylinder internal combustion engines designed for small UAV applications, with power outputs from 2.2 to 8.61 kW and a capacity range from 20cc to 140 cc. Delivering low emissions, low fuel consumption and turnkey heavy-fuel operation, and available in air-cooled and liquid-cooled versions, they are ideal for fixed-wing, rotary-wing and hybrid drones.
The lightweight, fuel-efficient propulsion solutions are easy to calibrate and provide consistent performance. RCV Engines’ unique combustion system has no injectors in the combustion chamber to decarbon, no valve clearances to adjust, and features shielded spark plugs, resulting in high reliability and low maintenance.
In addition to off-the-shelf units, RCV can provide engines specifically customized for your unique UAV designs.
