Diesel particulate filter testing

  • 19-Jun-2008 02:13 EDT


The Cambustion DPG is a diesel-fueled system used for diesel particulate filter (DPF) testing. The device allows a soot composition similar to that of many diesel engines and offers the capability to study different fuels such as biodiesel. Computer control of the burner, airflows, and temperatures ensures good repeatability of soot output. The system preheats the DPF to the loading temperature, thus allowing temperature and filtration effects to be separated and affording better evaluation of filtration performance of different media. A range of monitoring techniques to study DPF efficiency in real time can be fitted to the DPG, and results can be recorded into the automatically generated test report. The unit can regenerate a filter, allowing studies such as maximum soot load tests.
