Generac Power Systems have designed two new gaseous-fueled engines for use in the brand’s industrial power systems. The 9-L engine will be used on the brand’s 80-kW and 100-kW generators. The 12.9-L engine will be used on the 150- to 300-kW generators. Stainless steel intake and exhaust valves ensure durability, while hypereutectic cast aluminum pistons result in quieter operation and longer piston ring life.
