E3 Rich-Burn Gas Engine Control System Datasheet

Product Specification 03396 (Rev. A) E³ Rich Burn System with StableSense* Technology Applications Woodward's E³ Rich Burn control system provides highly stable, closed-loop control of air-fuel ratio on engines using three-way catalysts, to help engine owners meet regulated emission levels without operator adjustment. The exclusive StableSense* technology maintains up-time and catalyst performance by using the only industrial-gas-engine-specific O2 sensor. The E³ Rich Burn system is designed for use on stoichiometric, spark-ignited natural-gas engines used in gas compression, power generation, pumping, and other stationary applications ranging from under 300 kW (400 hp) to over 2 MW (2700 hp). The system is the latest in the Woodward line of E³ All-Encompassing Engine and Emissions control systems designed to meet the performance and reliability needs of gas engine manufacturers, owners and operators. System Overview The E³ Rich Burn system is a fully integrated engine control solution. It can be used as a stand-alone air/fuel ratio controller or as a complete gas engine emissions and engine control. The system features exclusive StableSense technology, to optimize the amount of time the engine remains in compliance. The StableSense technology contains special software and uses an industrial natural gas O2 sensor that is unaffected by engine exhaust methane and hydrogen. The E³ Rich Burn system has full authority over spark, fuel, and air. Additionally, diagnostics such as misfire detection as well as other health monitoring and engine protection are integrated into the system. E³—A fully integrated system for increased reliability: ? Air-fuel ratio control (base system) ? Integrated speed/load control (optional) ? Ignition control (optional) ? Engine protection o Full misfire detection for increased catalyst life and engine diagnostics o Overspeed monitoring for immediate engine shutdown o Start fuel limiting for easier, more consistent starting ? Scalable from small mono- to large stereo-fuel systems The E³ Rich Burn system incorporates Woodward’s full range of gas engine components: ? Woodward Integrated fuel valves and engine throttle bodies, from 16 mm to 180 mm ? Fixed-venturi mixers ? Ignition systems (Woodward IC-920 or IC-922) Engine health and diagnostics are integrated to ensure the engine remains in a safe operating mode. *Trademark of Woodard, Inc. **—Trademark of Schneider Automation Inc. ?
