UREA SELECTIVE CATALYTIC REDUCTION (SCR)
The urea SCR system reduces nitrogen oxides (NOx) in exhaust emissions. The
system uses diesel exhaust emission fluid (DEF) as a reducing agent and hydrolyzes
it into ammonia (NH
3
) using the heat from exhaust emissions. The nitrogen oxides
(NOx) are then reduced to nitrogen and water and purified by the generated ammonia.
Diesel exhaust emission fluid is a clear, colorless and harmless aqueous solution. It is
normal for diesel exhaust emission fluid to emit an odor in some circumstances.
When storing ;
•
Seal the diesel exhaust emission fluid container to prevent evaporation and
store it indoors or in places that are well ventilated and not exposed to direct
sunlight.
•
When stored, the expiration date of diesel exhaust emission fluid varies
depending on the temperature of the storage location. Contact your service for
details.
When refilling ;
•
Do not put anything other than diesel exhaust emission fluid in the diesel
exhaust emission fluid tank.
•
When refilling diesel exhaust emission fluid, doing any of the following may
cause a fire or malfunction of the urea SCR system.
- Diluting with water or other liquids
- Adding gasoline or diesel fuel
How to add
diesel exhaust emission fluid
1. Set the starter switch to the "LOCK" position and stop the engine.
2.
Slightly loosen the cap of the DEF tank and wipe off any dust or dirt adhered to the
cap or supply inlet.
3.
Turn the tank cap slowly to open the tank.
4.
Add DEF up to the "F" line while viewing the level gauge mounted in front of the
DEF tank.
5.
Turn the tank cap to securely install it to the DEF tank.
