Drake Controls supplies Woodward electronic engine control systems for natural gas, biogas, landfill gas, and dual fuel engine applications. From E³ full-authority emissions controls and fuel blending systems to speed governors, air-fuel ratio controls, ignition systems, and actuators, we provide complete solutions for power generation, compression, and pumping service.
Engine & Emissions Controls
E³ Rich Burn
Closed-loop air-fuel ratio control with StableSense O₂ sensor for three-way catalyst engines.
E³ Lean Burn
Full-authority lean-burn control for variable fuel quality including landfill and digester gas.
E³ Fuel Blending
On-engine fuel blending via TecJet valves. No plant-level blending facility needed.
L-Series A/F Ratio
Closed-loop air-fuel ratio control for small stoichiometric engines with three-way catalysts.
IC-920/922 Ignition
Ultra-high-energy ignition system for lean-burn and misfire-prone gas engines.
Actuators & Governors
ProAct ISC
Integrated speed control actuator for gas engine fuel racks and throttle bodies.
F-Series Modular
Electric bi-directional actuator for fuel rack, throttle, and wastegate positioning.
UG Governor
Industry-standard mechanical-hydraulic governor for gas engines.
