Supply module AdBlue MERCEDES RE-A0001405478

What is the AdBlue pump for a MERCEDES-BENZ trucks:

• The AdBlue supply module (AdBlue pump) is one of the key elements of the internal combustion engine. For the most part, these are trucks, buses and construction machinery.

• It is responsible for pumping the fluid (urea) that allows the decomposition of harmful nitrogen oxides in the catalytic converters of motor vehicles.

• After starting the engine, AdBlue, i.e. a urea solution, is distributed in the catalytic converter, where it turns into ammonia and carbon dioxide. As a result, nitrogen and water vapor are formed.
  
  
• Since 2014, the EURO 6 standard has been in force, which applies to all new diesel engines. The permissible emission of nitrogen oxides is 80 mg/km.

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.
