Subaru was the first to offer chain-driven overhead cam (OHC) technology in the small, air-cooled engine market with its Subaru Industrial EX engine series. A standard for high-performance automotive engines, 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. With fewer moving parts, OHC engines produce less mechanical noise than competitive technologies and offer better cooling performance to combat overheating.
