Abstract：Based on the diesel bus with oxidized catalyst (DOC) and catalyzed particulate trap(CDPF), an experimental study was conducted, which investigated the impacts of fresh/aged CDPF with different amount precious metal loads of 15g/ft3(type A)、25g/ft3(type B) and 35g/ft3(type C) respectively on characteristics of PAHs from particle emission of diesel engine under China typical city bus driving cycle (CCBC). The results showed that after using fresh and aged CDPF, PAHs emission was reduced significantly, at least by 93%. Compared to aged CDPF, the effect of reducing PAHs emission by all three fresh type CDPF was similar, the extreme difference was only 0.009ng/cm2.The effect to reduce toxicity of PHAs emission of all three aged type CDPF were better than when they were fresh. Besides, the effect of reducing PAHs emission and toxicity of aged B type CDPF was better than aged A and C type CDPF.
