摘要: 为深入研究柴油机微粒捕集器的微波再生机理,基于模糊综合评价法,结合层次分析主观赋权法与熵值赋权法,建立了柴油机微粒捕集器微波再生系统的两级模糊综合评价模型,完成了微波功率、微粒沉积量、排气温度、排气氧含量、排气质量流量对再生效率、再生时间、再生峰值温度及再生性能权重的定量分析,并得到了各因素取不同值时的再生性能评价结果.研究表明: 排气温度对再生效率与再生时间的影响最大,权重分别为0. 4701 与0. 5361; 微粒沉积量对再生峰值温度的影响最大,权重为0. 424 4; 再生效率在再生性能中所占权重最大,为0. 6162.

Abstract:

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.

Key words: particulate filter, microwave regeneration, fuzzy comprehensive evaluation, analytic hierarchy process, entropy weight
