Processing Requirements

Injector nozzles require multi-hole arrays at 80-120μm diameter with extremely high hole wall finish

Technical Solution

EDM and laser hybrid processing — EDM pre-drilling followed by laser hole wall finishing

Processing Results

• Hole wall roughness Ra<0.2μm
• Spray cone angle consistency ±1°
• 8% fuel efficiency improvement
