摘要：

In order to further reveal the microwave regeneration mechanism of diesel particulate filter, a two-level fuzzy comprehensive evaluation model for the microwave regeneration system, which combines the AHP (Analytic Hierarchy Process) subjective weighting and the entropy objective weighting methods, is established based on the fuzzy comprehensive evaluation method. Then, a quantitative analysis is carried out to obtain the weights of microwave power, deposited particulate mass, exhaust temperature, oxygen content, mass flow on the efficiency, time, peak temperature and property of the regeneration. Finally, the regeneration properties affected by various factors are evaluated. The results show that exhaust temperature has the greatest effect on the regeneration efficiency and time, with the weights respectively being 0.4701 and 0.5361, that the mass of deposited particulate has the greatest effect on the regeneration peak temperature, with the weight being up to 0.4244, and that the regeneration efficiency is of the maximum weight on the regeneration efficiency, namely 0.6162.
