Selective Catalytic Reduction(SCR) System
With emissions regulations becoming more and more severe in Europe, America and Japan/Korea, SCR System tends to be generalized in Diesel Engine after treatment system reducing NOX(Nitrogen Oxides) emissions with urea injected in the exhaust line. ("AdBlue" in Europe and Diesel Exhaust Fluid "DEF" in America).
SCR is a means of converting nitrogen oxides, also referred to as NOX with the aid of a catalytic into diatomic nitrogen, N2 and water, H2O.
A gaseous reductant, typically anhydrous ammonia, aqueous ammonia or urea, is added to a stream of fuel or exhaust gas and is absorbed onto a catalyst.
The SCR controller (or Exhaust Control Unit), shall control urea delivery to the injector, monitor urea level, temperature and quality in the additional urea tank, control heaters to avoid urea freezing in cold conditions and communicate with main engine ECU to exchange depollution status and performances.
