Abstract

Diesel vehicles are equipped with after-treatment devices, such as DPF. Meanwhile, DPF is damaged by a combination of regenerative processes and unclear factors. If the DPF substrate is damaged, the filtration performance will deteriorate, thereby resulting in excessive levels of fine dust being emitted while driving. In this study, CR X-ray techniques were used in order to determine whether a DPF was damaged without prior removal. In order to verify the technological feasibility, an X-ray imaging of the DPF removed from the driving vehicle was conducted by using an X-ray generator, as well as an IP reader and a CR reader. Optimal irradiation conditions were established for each DPF size. Verification of images acquired under optimal irradiation conditions confirmed the possibility of diagnosis for damages, such as crack, melting, and hollow damage.
