DNOX dosing module MERCEDES R-A0001407139

DNOX dosing module R-A0001407139 for MERCEDES:

• The dosing module in heavy-duty vehicles serves a similar function to that in passenger vehicles. It is a device responsible for delivering a dosing fluid (most commonly AdBlue or DEF) to the SCR system.

• The primary goal of the dosing module in heavy-duty vehicles is the reduction of nitrogen oxide emissions, contributing to the protection of the natural environment and compliance with emission standards.

• In the transportation sector, particularly in the case of heavy-duty vehicles, effective control of NOx emissions is of significant importance due to the extensive number of miles traveled and the potential impact on air quality.

• Regular maintenance of the dosing module is crucial to ensure its proper operation. The manufacturer may recommend periodic inspections and monitoring of the dosing fluid level.

SCR technology
SCR technology consists in converting (reducing) nitrogen oxides into non-toxic nitrogen and water vapor in a catalyst using ammonia as a reducer. In commercial vehicles, a non-toxic, odorless, 32.5% aqueous solution of urea is used. Under the control of the engine management system, the urea solution (NOX), stored in a separate tank, is dosed in the desired amounts into the hot exhaust stream. Under high temperature exhaust gases, the urea solution decomposes to ammonia and carbon dioxide. Ammonia then reacts with nitrogen oxides to form free nitrogen and water vapor.

Denoxtronic Bosch systems have been used since 2004 in trucks equipped with diesel power systems. They add AdBlue to the SCR catalyst to reduce NOx emissions from exhaust gases by up to 85%. As a result, lorries meet the exhaust emission standards from Euro 4 to Euro 6.
