Medium and heavy-duty trucks manufactured starting on January 1, 2010 are required to meet the EPA Emission Standards. The majority of truck manufacturers chose to use selective catalytic reduction (SCR technology to meet the standards. As part of SCR technology, Bosch provides the Denonxtronic 2.2 dosing system which injects urea into the exhaust which interacts with the SCR catalyst to reduce the NOx emissions level. The supply module contains a main filter which filters the urea being pumped into the dosing module.
UREA Filter Replacement
The filter needs to be replaced per the manufacturer's scheduled maintenance requirements. The Bosch Urea Filter for diesel applications is designed for and supplied to OE manufacturers, and offers one SKU which covers up to 69% of Class 4 through Class 8 trucks in operation. When it comes time to change the filter, the exclusive extraction tool included grips the filter to make removal of the filter easier, along with the instruction sheet supplied in every box.
