E3 Lean-Burn Air-Fuel Ratio Control
Woodward E3 lean-burn control systems include an E3 controller, inlet air throttle, fuel trim valve, and oxygen sensor to provide excellent and stable control of the engine lean-burn combustion process to enable high thermal efficiency at low exhaust gas emission levels.
Woodward E3 lean-burn combustion control systems offer an optional integrated engine speed control. Ignition control is supported with the latest CD ignition control systems, like Woodward’s IC-920 or IC-922. The E3 lean-burn control system is designed to integrate the CD ignition systems, enabling the engine to operate at a very lean-burn limit and achieve high thermal efficiency.
