The wall Flow Diesel Particulate Filter (DPF) is one of the major technologies used to meet the current and future Particulate Matter (PM) emission regulations on heavy duty applications. This technology, however, adds significant engine backpressure. This has a negative impact on fuel consumption, and in turn, on CO2emissions.In order to better understand the DPF impact on engine backpressure, a large amount of DPF pressure drop models have been published, especially over the last ten years. Even though each published model has slight variations, they were all derived from Konstandopoulos approach of the problem [1]. However, in 1998, Opris developed a unique pressure drop model [2,4], that is radically different from Konstandopoulos’ method. In the Opris model, Navier-Stockes equations were analytically solved in the context of a DPF. Along with Darcy’s law, and the 2D flow-field solution, a fundamental expression of the DPF pressure drop was obtained.In this paper, Opris’ model has been improved to better account for the impact of ash and soot on the pressure drop. Also, the capabilities of the model have been extended such that the pressure drop can be calculated for asymmetric cells technology DPFs.
