The Woodward IC-920 and IC-922 are state-of-the-art capacitive-discharge ignition system controllers designed for spark-ignited engines in gas compression, power generation, and other industrial applications. Featuring ultra-high energy output, advanced diagnostics, and RS-232 ServLink programming, these controllers support up to 20 (or optionally 24) ignition coils with user-controlled energy levels.
Key Features
IC-920 (Standard Strike)
- Standard-strike energy for up to 20 ignition coils (24 optional)
- Adjustable stored energy up to 170 mJ
- Suitable for standard industrial engine applications
IC-922 (Big Strike)
- Big-strike energy for up to 20 ignition coils (24 optional)
- Adjustable stored energy up to 340 mJ
- Ideal for high-BMEP or misfire-prone engines
Common Features
- 16-bit CPU with sensor signal conditioning
- Three timing sensors: crankshaft position, camshaft position, engine speed
- Timing control via potentiometers, 4–20 mA, 0–5 Vdc, or 5-point speed curve
- Adjustable spark energy for optimized plug life
- Continuous ignition system monitoring and fault diagnostics
- RS-232 ServLink interface with Windows-based service tool
- Programmable overspeed shutdown setpoint
- Configurable from 2 to 20 (or 24) cylinders
- 4-stroke up to 1,800 rpm / 2-stroke up to 900 rpm (20-cyl); 1,500/750 rpm (24-cyl)
Applications
- Spark-ignited industrial gas engines
- Gas compression stations
- Electric power generation
- Lean-burn and high-BMEP engine applications
- Engines prone to misfire requiring high-energy ignition
