WOODWARD 9906-707 E3 Gas Engine Controls

Woodward's E3 gas engine control system is a highly integrated solution that precisely controls the air-fuel ratio of gas engines. It can be applied to a variety of industrial gas engines, effectively improving engine efficiency and reducing emissions.

 

 

Product Configuration
E3 Rich-Burn Trim System: Designed for engines commonly found in gas compression and many power generation or irrigation pump applications. It analyzes and controls all engine and catalyst functions to optimize engine compliance time for stoichiometric, spark-ignited natural gas engines from 300kW to over 2MW.
E3 Lean-Burn Trim System: Used to control lean-burn industrial gas engines from 300kW to 2000kW (400-2700hp), the high-precision closed-loop control system helps customers meet regulatory emission levels while maintaining engine performance over a wide range of fuel qualities.
E3 Full Authority System: A fully integrated engine control solution with full control over spark, fuel and air. In addition, it integrates diagnostic functions such as knock, misfire, and other health monitoring functions to achieve precise speed regulation and air-fuel ratio control, and can flexibly respond to large changes in fuel quality. It is suitable for application scenarios with variable fuel supply energy quality, such as landfills, wastewater treatment plants, or biogas recovery plants.

 

Product Features
E3 Rich-Burn Trim System:
Greatly reduces non-compliant downtime.
Adopts exclusive StableSense* technology to maintain normal operation time and catalyst performance by using the only industrial gas engine-specific O₂ sensor.
Equipped with engine and catalyst health monitoring and alarm functions.
Ensures stable engine start-up under various conditions.
Integrated engine protection and diagnostic functions to ensure safe engine operation.
Applicable to single-row and double-row engines, double-row engines can achieve automatic online cylinder bank balancing to improve engine performance.
Integrated design improves reliability and reduces overall cost.
Strong scalability to meet all customer needs.
Supports RS-485 serial Modbus** slave multi-point communication with a baud rate of up to 115kbaud.
E3 Lean-Burn Trim System:
Allows the engine to use different fuels while maintaining engine efficiency.
Integrated design reduces system complexity and overall cost.
Speed-density based air-fuel ratio controller.
Without gas quality sensor, it can handle gas quality changes of ±10% CH₄; with external gas quality analyzer, it can handle gas quality changes of 100-2500BTU/scf (3.7-93.1MJ/m³).
Flexible configuration.
E3 Full Authority System: In addition to some of the above features, its fully integrated approach can flexibly adapt to fuel quality changes while providing precise control, providing strong support for stable operation and maintenance management of the engine.
