SCR is an after-treatment system that is separate from the main engine function. This technology enhances engine performance without compromising horsepower or torque. The SCR after-treatment system transforms the nitrogen oxides (NOx) produced during the combustion process into nitrogen and water, which occur naturally in the atmosphere, through a chemical reaction with a diesel exhaust fluid (DEF).
SCR technology is extremely fuel efficient because it allows the engine to generate maximum power and optimizes the combustion process. The main components of the SCR system are the supply module, diesel exhaust fluid (DEF) tank, dosing module and SCR catalyst. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
