Abstract: To meet the demand for rapid, repeatable aging tests of diesel aftertreatment systems, this study designs and optimizes a dedicated diesel burner system via CFD. A parametric 3D model was built in Pro/E, and structural optimization was performed on the swirl plate and dilution mixing section. The inclined-hole swirl plate produces a stronger recirculation zone, lowering backpressure and preventing flame impingement. A rotary deflector was developed for the dilution section to enhance mixing uniformity and reduce wall thermal erosion, showing better performance than the original and baffle designs. Parameter analysis confirms stable performance over the operating range. Bench tests show that the burner reaches a maximum exhaust temperature of 1033°C and a flow rate of 2538 kg/hr. SCR catalyst aging tests demonstrate that NOₓ conversion efficiency falls below 50% after 100 hr, validating the system's effectiveness. This burner provides a reliable, low-cost platform for catalyst rapid aging, supporting the development of aftertreatment devices. [ABSTRACT FROM AUTHOR]
