摘要

In terms of diesel oxidation catalyst(DOC)and catalyst diesel particulate filter(CDPF)diesel engine after treatment system, the effects of ash deposited in CDPF on the BTEX(Benzene, Toluene, enthylbenzene and xylene) and carbonyl compound emission were studied. Research results indicate that the tendency of the BTEX emission before CDPF with ash is U shaped with the ash accumulation. Meanwhile, the BTEX emission after CDPF with ash increases clearly compared with the BTEX emission before CDPF with ash in different working conditions and the BTEX contents are also changed in different degrees. The total carbonyl compound emission before CDPF with ash increases obviously compared with the CDPF without ash. In addition, the total carbonyl compound emission after CDPF with ash decreases obviously and the carbonyl compounds change a lot in different working conditions compared with the compounds before CDPF with ash.
