It has been reported that a fraction of the ash generated by an engine can slip through the diesel particulate filter (DPF), causing malfunctioning of the OBD. To investigate the mechanism of this ash slip, repeated experiments are necessary. However, ash formation in an engine is very slow. In this study, a stable and accelerated ash generation system was constructed using a diffusion flame burner. Ash samples were analyzed by HPLC, XRD, and SEM-EDX. The produced ash contained CaSO4, CaS, Ca3(PO4)2, Ca5(PO4)3(OH), CaO, ZnS, and ZnO, and had particle sizes of approximately 1 - 10 μm. These characteristics are similar to those of the ash generated by an engine system, which indicate that the system constructed using a diffusion flame burner can generate ash comparable to that generated by an engine.
