摘　　要：利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温升效应． 结果表明，过滤体上捕集的烟碳量对催化滤烟器在氮气中的微波加热温升至关重要，烟碳量的微小增加，可引起滤烟体温度的显著升高． 另外，当微波加热过程中隔离氧气时，滤烟体上出现了明显的金属氧化物催化剂被碳还原的现象．By using of the microwave heating setup and engine test bed, an experimental study has been carried out to investigate the temperature increase behavior of diesel soot catalytic filter in an inert atmosphere under microwave irradiation. The results indicated that the content of soot trapped in filters violently influenced the temperature increase of filters by microwave heating. When the soot content exceeded 1 98% in the Cu V trap, the carbothermic reduction phenomenon is observed. A duplicate experiment using electric TG DSC MS instrument showed no such reaction occurred.
