E3 Lean Burn Gas Engine Control System

Woodward's E3 Lean-Burn Trim gas engine control system controls the air-fuel ratio by controlling the fuel metering trim valve. The system is designed to control lean-burn industrial gas engines used in numerous power generation, pumping, and other stationary applications ranging from 300 kW to 2000 kW (400–2700 hp). The highly accurate, closed-loop control system helps customers meet regulated emission levels while maintaining engine performance over a wide range of fuel qualities.

The E3 Lean-Burn Trim system is a fully integrated engine control solution with full authority over spark, fuel, and air. Additionally, diagnostics such as detonation and misfire, as well as other health monitoring, are integrated into the system.

This fully-integrated approach permits precise governing and air-fuel ratio control while remaining flexible enough for large variations in fuel quality.

System Features:

• Integrated approach reduces system complexity and reduces overall cost
• Scalable to meet entire range of customer needs
• Integrated engine protection and diagnostics to ensure safe engine operation
• Power generation or mechanical drive applications
