• NOx (Oxides of Nitrogen)
– Causes smog
– Is created by high combustion temperatures
• 2010 NOx regulations could require
direct regular attention for the 1st time
– Drivers monitor, replenish urea
– Technicians maintain SCR system
What is NOx and why worry about it?
Air – 80% nitrogen, 20% oxygen
Heat from combustion forms NOx

2010 Alternatives
• Run hot combustion, create NOx, reduce out of
engine
– SCR effective but requires customer involvement
• European technology
• All 2010 SCR engines will retain EGR
– NOx adsorbers, Lean NOx traps do not scale
– GE / Tenneco SCR catalyst not mature
MaxxForce® is a registered trademark of , Inc.
• Run cool combustion with EGR, reduce NOx
– Best for customers
– Doable with High Pressure Common Rail - timing
challenge• 5 million engines produced with High Pressure Common Rail
– Large investment in R&D

Development Issues and Solutions
• Development - EGR runs engine “cold” with
reduced oxygen
– Issue: Condensation can form
– Solution: Cycle EGR 100-130 degrees
– Maintain or reduce condensation
MaxxForce® is a registered trademark of , Inc.
• Cool combustion reduces efficiency
– Issue: Could reduce power and fuel economy
– Issue: Could increase DPF regen, oil intervals
– Positive: Reduced thermal, mechanical loads
– Solution: Increase fuel pressure, recalibrate
• Restores power and efficiency to 2007 levels
• Restores oil intervals, DPF regen to 2007 levels

Timing challenge
Development Strategy:
mature the technology
for customers
• EPA and CARB reward cleaning environment earlier
• Rules assure cleaner environment forever
