In order to effectively evaluate the anti-deposition ability for aftertreatment system(ATS) of diesel engine, an evaluation method that is based on NH3 distribution uniformity testing and simulation results, liquid film temperature simulation results, steady-state and transient-state deposition risk testing results was proposed. Several influences were also considered in the method including engine emissions and exhaust temperature characteristics, urea injection temperature calibration and transient injection control parameters calibration. This method can not only quantitatively evaluate the overall anti-deposition ability of ATS, but also quantifies the degree to which the overall anti-deposition ability is affected by urea injection system, mixing system, ATS software calibration, engine emissions and exhaust temperature characteristics, which indicating the specific optimization directions for improving the anti-deposition ability of ATS clearly.
