Subaru Industrial Power Products’ EX Series offers more power, easier starts and a lower total cost of ownership than same-class competitive engines. The EX Series engines are the first to utilize high performance chain-driven overhead cam (OHC) technology in the industrial air-cooled market and are ideal for use in general construction and compaction equipment, portable generators, pumps, compressors and other industrial engine applications.
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. Designed with a highly efficient pent-roof-type combustion chamber, the EX engines are able to utilize a high compression ratio, producing higher power and torque while limiting exhaust emissions and fuel consumption.
