RCV Rotary Valve Multi-Fuel 4-Stroke Engines

Utilizing patented rotary valve technology and a four-stroke engine, RCV Engines designed for low emissions, low fuel consumption, and turn-key heavy-fuel operation. With their single-, twin-, and four-cylinder designs, these engines are easy to calibrate and provide consistent performance with RCV Engine’s unique combustion system. With no injectors in the combustion chamber to carbon up, no valve clearances to adjust, and shielded spark plugs, RCV engines have the high reliability and low maintenance that many midsize drone applications require. As the key features demonstrate, the RCV engine fits a variety of applications, including fixed-wing, rotary-wing, hybrid, marine, and portable power.

RCV Technology Key Features Include:

• Four-stroke cycle for low emissions and fuel consumption
