AB - Diesel particle filter (DPF) is an effective way of reducing soot particles in the exhaust of diesel engines. The new emission regulations for non-road machineries effectively require that they are equipped with DPFs. However, these devices can be damaged and lead to an increase in the concentration at the filter outlet, which can exceed the emission limits. A study has been conducted to evaluate the impact of a micro-leak, created within a ceramic honeycomb filter, on its performance, i.e. filtration efficiency and pressure drop. The measurements carried out, as well as a modelling of the leak phenomenon, show that the simple measurement of the pressure drop is insufficient for the detection of these micro-leaks, which result in a significant drop in efficiency, all the more important as the flow resistance and efficiency of the filtering media is high.
