柴油發(fā)動機(jī)尾氣顆粒物研究進(jìn)展

摘要: 柴油發(fā)動機(jī)尾氣顆粒物的形成是一個復(fù)雜的物理化學(xué)過程, 對其進(jìn)行研究有助于發(fā)動機(jī)尾氣排放的控制, 并對改進(jìn)發(fā)動機(jī)和排氣管道的結(jié)構(gòu)設(shè)置有指導(dǎo)意義. 從物理化學(xué)特性、實(shí)驗(yàn)測量、數(shù)值模擬等方面對柴油發(fā)動機(jī)排放顆粒物研究的最新進(jìn)展進(jìn)行了綜述, 并認(rèn)為在統(tǒng)一系統(tǒng)中綜合考慮各種尺度顆粒的數(shù)值模擬工作還需進(jìn)一步的發(fā)展.
