Performance Verification of Next Generation Diesel Particulate Filter 2010-01-0531

The Inlet-Membrane DPF which has a small pore size membrane formed on the inlet side of the body wall has been developed as a next generation diesel particulate filter (DPF). It simultaneously realizes low pressure drop, small pressure drop hysteresis, high robustness and high filtration efficiency. The low pressure drop improves fuel economy. The small pressure drop hysteresis has the potential to extend the regeneration interval since the linear relationship between the pressure drop and accumulated soot mass improves the accuracy of the soot mass detection by means of the pressure drop values. The Inlet-Membrane DPF's high robustness also extends the regeneration interval resulting in improved fuel economy and a lower risk of oil dilution while its high filtration efficiency reduces PM emissions.
The concept of the Inlet-Membrane DPF was confirmed using disc type filters in 2008 and its performances was evaluated using full block samples in 2009. In this paper, the performance, reliability and durability of the Inlet-Membrane DPF were confirmed under different conditions. The Inlet-Membrane DPF showed low pressure drop and small pressure drop variation under several engine operation conditions as well as sufficient durability verified under several evaluation conditions.
