Challenges With In-Cylinder NOx Control
 High EGR rates: increased risk of EGR condensation
– Power cylinder corrosion; water in oil
– Reliability and durability
 High EGR rates: high heat rejection
 5 - 9% fuel economy disadvantage
 Increased DPF regenerations
 Power density and torque limitations
 Throttle response and drivability

The Facts about the Fluid DEF Properties
 It is a solution comprised of:
– 32.5% automotive grade urea
– 67.5% deionized water
 DEF is safe to handle and store
– Non-toxic
– Non-polluting
– Non-flammable
 DEF freezes at 12° F (-11° C)
– Frozen DEF does not impact start up and normal
operation of the vehicle
