Based on Domestic Split DCU and BOSCH ECU Cross Validation Study
At present,SCR(Selective Catalytic Reduction)technology is one of the most important means to reduce NOx in diesel exhaust.Along with the advancement of localization process,highly integrated post-pro-cessing control unit DCU is widely attention,the paper theoretically explains the localization of post-processing control system information interaction between DCU and engine control unit ECU,and through the discharge cy-cles and vehicle road test shows that the method satisfies the requirement of China'phase six laws and regula-tions,Further expansion and affirmation of domestic DCU application market potential.
