Description
Woodward 8290-191 Electrically Powered Governor (EPG) System
The
Woodward 8290-191 is a compact, 24V droop speed controller designed for diesel engines and other prime movers requiring precise speed regulation without mechanical drives or hydraulic oil systems. As part of the
EPG (Electrically Powered Governor) series, it integrates an electronic speed control unit, compatible electric actuators (e.g., 1712/1724 or 512/524), and a magnetic pickup for real-time feedback. Key features include dual dynamic control, start-fuel limiting for smoke reduction, and compliance with EU directives. Ideal for mobile equipment, small power generation systems, and industrial machinery, the
8290-191 offers plug-and-play compatibility with Woodward’s actuator lineup and supports both isochronous and droop control modes.

- No Hydraulic/Mechanical Complexity: Eliminates the need for oil pumps or gear drives, reducing maintenance costs.
- Dual Dynamic Control: Switch-selectable algorithms optimize response for different load conditions.
- Compact Design: Lightweight (4.3 kg) and space-efficient (263 × 58 × 28 mm) for mobile applications.
- Load Sharing: Compatible with accessories for parallel operation in power generation setups.
- Start-Fuel Limiter: Prevents excessive fuel injection during startup, minimizing emissions.
Industries:
- Small-scale power generation (diesel gensets).
- Mobile equipment (construction machinery, agricultural vehicles).
- Industrial drives (pumps, compressors).
Case Study:
A European construction firm deployed the 8290-191 on its diesel-powered excavators to improve fuel efficiency and reduce downtime. By integrating the EPG system with 1724 actuators, the firm achieved 15% faster load response and a 10% reduction in fuel consumption, translating to annual savings of $20,000 across its fleet.
Compared to traditional mechanical or hydraulic governors, the 8290-191 offers faster installation (no oil lines or mechanical linkages) and lower lifecycle costs. Unlike some digital alternatives, it requires no external power beyond the battery, making it ideal for remote or off-grid applications. Its modular design also allows for easy field upgrades, such as adding load-sharing modules.
- Voltage Compatibility: Confirm 24V system requirements; 12V alternatives are available (e.g., 8290-190).
- Actuator Size: Choose 1712/1724 for heavy-duty applications or 512/524 for lighter loads.
- Environment: Ensure the unit is protected from moisture (IP54-rated enclosure recommended for outdoor use).
- Battery Capacity: Use a 5A charger to maintain system reliability during extended operation.
- Magnetic Pickup Alignment: Properly position the sensor to avoid false speed readings.
- Software Configuration: Calibrate start-fuel limits based on engine type to prevent overloading.
