LDI Technology

What's the goal of LDI (lean direct injection)?

  • Reduce emission while maintaining flame stability
  • Inject fuel directly into flame zone to avoid flashback
  • Fuel-lean combustion, reduce NOx emission
  • Multi-swirler injection for uniform F/A mixing and low residence time

Fuel-staging features to simulate flight conditions (idle, cruise, SLTO)

Current results from testing have been very promising:

  • Low equivalence ratio
  • Ultra-low LBO

+ Future testing: Emission analysis on High Pressure Test Rig #1
