DEF fluid in heavy equipment !!

[1strodeo]

This is a brief explanation thats in a powerpoint presentation I have on it :

SCR works by injecting a very precise amount of DEF into the vehicle’s hot exhaust stream where the urea is converted into ammonia.
Once inside the SCR catalyst, the ammonia gas forms a chemical reaction with the NOx emitted by the engine.
As a result of this chemical reaction, SCR converts NOx into water vapor and harmless nitrogen gas.

Now that's as clear as the exhaust as I see out of trucks . Not picking on anyone but as I understand it you can drink it and laugh yourself silly ? Mike who has enough trouble with the electronics on a RC truck . Maybe soon I'll be taking my 1945 International A to work !
