Subaru EX Series Engines

Robin America introduces Subaru’s EX Series engines. These engines are the first to utilize high performance chain-driven overhead cam (OHC) technology in the industrial air-cooled market. Featuring four models with power ranges from 4.5 hp to 9 hp. Chain-driven OHC technology allows the intake and exhaust valves to be positioned for optimum engine performance. This offers lower resistance for the air/fuel mixture flow. An automatic decompression system reduces the required recoil pulling force by 30- to 40-percent when compared with overhead valve (OHV) engine designs. In conjunction with the newly designed combustion chamber, starts are fast and easy with no perceptible kickback.
