Noxguard Diesel Exhaust Fluid and some interesting facts

We would like to share some interesting facts regarding Noxguard Diesel Exhaust Fluid and it’s performance inside the Selective Catalytic Reduction (SCR) system of a diesel engine.
First of all, the difference between the combustion process of a gasoline engine and a diesel engine are significant. Diesel engines, in order to combust, require high pressure (no spark plugs) and lots of air, about 65 parts of air for every part of diesel; meanwhile gasoline engines use 14 parts of air per 1 part of gasoline. Thus the reason for NOX emissions to be higher in diesel. Also gasoline engines operate at lower temperatures than diesel engines.
And now, the magic of the chemistry of our Noxguard DEF inside the SCR System step by step:

 

 

Noxguard Disesl Exhaust Fluid Chemistry Facts

 

 

  • Combustion is performed in the engine, and emissions are released.
  • In the SCR system, Noxgard DEF is sprayed to the fumes and the chemical magic begins.
  • With the high heat of combustion, the DEF converts to ammonium.
  • Ammonium is mixed with the NOX of the fumes, and there is water vapor present too.
  • The result of this mixture produces Nitrogen (which we find naturally in the air we breathe).
  • And on the other side we obtain water, yes water.

 

 

The Chemistry looks like this:

 

  • Ammonium which are 3 atoms of Hydrogen plus one of Nitrogen (4NH3).
  • Plus NOX which is 1 atom of Nitrogen plus 2 atoms of Oxygen (2NO2).
  • Adding in Oxygen (O2).
  • Results in Nitrogen (N) plus Water molecules (H2O).

SURPRISINGLY MAGIC!

 

 

Yes, of course, you need the specially designed SCR system that has all the dosage technology and the filtration process to accomplish the job.
