Abstract

Selective catalytic reduction catalyst coated on filter (SDPF) is one of the important technical routes to meet the future Euro-Ⅶ emission regulations for engines. To efficiently control and optimize the SDPF, it is necessary to have a comprehensive understanding of its regeneration characteristics. Therefore, the temperature, particulate emission characteristics and reduction emission performance of SDPF under the drop to idle (DTI) regeneration with different soot loads were investigated. The results show that, during DTI regeneration, the SDPF inlet outer-ring temperature was the highest and the outlet outer-ring temperature was the lowest, the radial temperature gradient of the outer-ring was larger than that of the inner-ring, and the axial temperature gradient of the rear section was larger than that of the front section. As the soot load increased, the start of regeneration was delayed, the regeneration duration extended, and both the peak temperature and the maximum temperature gradient of the substrate increased. A rapid increase in the proportion of nucleation-mode particle at the SDPF outlet was a signal of the end of DTI regeneration. The higher the soot load, the higher the regeneration efficiency and the lower the particle filtration efficiency and NOx conversion efficiency of the SDPF after DTI regeneration.
