采用柴油机台架装置及微波加热装置，考察了柴油机催化滤烟器的微波加热再生效应．结果表明，过滤体上捕集的碳烟量对催化滤烟器在氧气中的微波加热燃烧再生至关重要，只有捕集的碳烟量超过某一下限值，滤烟器上的碳烟才有可能被微波加热至起燃温度； 但碳量也不可超过一上限值，否则滤烟器的微波加热催化再生可能失去控制，碳烟急剧燃烧产生的热量将使过滤基质烧结． 此碳烟上下限再生窗口随催化剂活性的差异而有所改变． 研究中还发现，在再生过程中，产物中ＣＯ和ＣＯ２ 的比率有较大波动．
Diesel engine bench device and microwave heating device were used to investigate the regenerative effect of microwave heating of diesel-catalyzed soot filter. The results show that the amount of soot captured on the filter body is crucial for catalyzing the microwave heating and regenerating of soot filter in oxygen. Only when the amount of captured soot exceeds a certain lower limit, the soot on the filter It may be heated by microwave to the light-off temperature; however, the amount of carbon should not exceed an upper limit, otherwise the filter regenerator may lose control due to the microwave heating of the soot filter, and the heat generated by the soot combustion will cause the filter substrate to sinter. The upper and lower regeneration windows of soot vary with the catalyst activity. The study also found that in the regeneration process, the product of CO and CO2 ratio fluctuations.
