Woodward 8290-039C
Product Overview
A compact, all-electric governor designed for precise isochronous speed control of diesel engines. It eliminates the need for a mechanical drive or hydraulic oil supply, making it ideal for prime movers with low-mass, low-friction fuel linkages. The EPG governor receives a speed signal from a magnetic pickup and drives an integrated electric actuator to adjust the engine’s fuel supply.
