What do you need to know about Adblue diesel exhaust fluid?
Adblue is one of two commonly used methods to reduce NOx emissions as part of a SCR.
How is Nox made that AdBlue removes?
AdBlue or Diesel Exhaust Fluid (DEF) is a solution of 32.5% Urea in de-ionised water. It is sprayed into the exhaust system of modern engines as part of a selective catalytic reduction system (SCR) to reduce NOx (nitrogen oxides) emissions from the exhaust that cause acid rain and lung problems. How is NOx made that Adblue removes?
Where does the AdBlue go in the tank?
AdBlue is always stored in a completely separate tank. However, in many vehicles the AdBlue filler will be located next to the fuel filler.
Where can I buy AdBlue fluid for my Mercedes?
First of all, check the AdBlue level and top it up if needed. You can buy AdBlue fluid from any Mercedes dealer, or you can get a generic Diesel Exhaust Fluid from auto part stores or gas stations. If there is a fault within the system, the following should be checked:
What happens when you put AdBlue in the tank?
If you drive your vehicle with the AdBlue in the tank, this can cause the fluid to be circulated throughout the fuel system. The fluid can cause corrosion to some metals and that will degrade the components of the fuel system. The first thing you need to do is to contact a mechanic to drain the tank.
How is AdBlue used in the exhaust system?
AdBlue is just another name for Diesel Exhaust Fluid or DEF. This solution of urea in water is injected into exhaust gases as a part of the exhaust treatment system called selective catalytic reduction or SCR. This process converts up to 90% of the harmful nitrogen oxides produced by the vehicle into nitrogen and water.
First of all, check the AdBlue level and top it up if needed. You can buy AdBlue fluid from any Mercedes dealer, or you can get a generic Diesel Exhaust Fluid from auto part stores or gas stations. If there is a fault within the system, the following should be checked:
What happens if my AdBlue system does not work?
Fault with the SCR system. No matter the cause, an AdBlue system that doesn’t work will not have any effect on the engine operation or performance. You can easily drive for years without AdBlue, without affecting your engine.
