New tractors, excavators, cranes and other mobile engines that run on diesel, but not on roads, are equipped with SCR technology, which requires AdBlue ®.
SCR technology and AdBlue ® for NOx reduction is now common in several types of non-road engines, eg:
- Agriculture / farm engines such as tractors and combine harvesters
- Mobile cranes
- Engines used in harbours and airports
- Excavators and engines used in mines or construction
