              SCR system                                                                                          DI
              Overview

              The Chinese meaning of SCR is selective catalytic reduction, which is to take 31.8% ~ 33.2% AdBlue (DEF)   EG
              as a reducing agent, and inject it into the exhaust gas stream, in the high temperature exhaust gas, DEF is
              atomized into ammonia, under the action of the reducing agent, the ammonia gas chemically reacts with the
                                                                                                                  TR
              nitrogen oxides (NOx) in the exhaust gas to produce harmless nitrogen and water.
