Spark-ignited engines

The Generac 9.0 L engine for 80kW and 100kW generators and the Generac 12.9 L engine for 150-300 kW generators.

Generac Power Systems has designed and manufactured two new gaseous-fueled engines specifically for use in several Generac Industrial Power systems: The Generac 9.0 L engine for 80 kW and 100 generators, and the Generac 12.9 L engine for 150 to 300 kW generators. In manufacturing its new engines, Generac used stainless steel for the intake and exhaust valves to ensure durability and long life. Stellite, a cobalt-based alloy, makes the valve seats especially resistant to corrosion and wear. Valve angles were reduced to minimize the friction that can result from using dry fuel. Hypereutectic cast aluminum pistons were chosen to resist thermal expansion for tighter clearances that result in quieter operation and longer piston ring life. Manufacturing its own engines also helps Generac ensure that it can deliver products to customers as quickly as possible. Each of the generators using one of the new Generac engines will retain all of its current features and configurable options. Both new engines will also meet all regulatory requirements.
