Initial studies using a conductometric soot sensor to monitor their filtering efficiency, i.e., to detect a malfunction of the DPF, are presented. The sensors consist of a planar substrate equipped with electrodes on one side and with a heater on the other. It is shown that at constant speed-load points, the time until soot percolation occurs or the resistance itself are reproducible means that can be well correlated with the filtering efficiency of a DPF. It is suggested to use such a sensor setup for the detection of a DPF malfunction.<\/jats:p>","DOI":"10.3390\/s100301589","type":"journal-article","created":{"date-parts":[[2010,3,1]],"date-time":"2010-03-01T11:29:23Z","timestamp":1267442963000},"page":"1589-1598","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":42,"title":["Conductometric Soot Sensor for Automotive Exhausts: Initial Studies"],"prefix":"10.3390","volume":"10","author":[{"given":"Gunter","family":"Hagen","sequence":"first","affiliation":[{"name":"Functional Materials, Bayreuth Engine Research Center (BERC), University of Bayreuth, 95440 Bayreuth, Germany"}]},{"given":"Constanze","family":"Feistkorn","sequence":"additional","affiliation":[{"name":"Functional Materials, Bayreuth Engine Research Center (BERC), University of Bayreuth, 95440 Bayreuth, Germany"}]},{"given":"Sven","family":"Wieg\u00e4rtner","sequence":"additional","affiliation":[{"name":"Functional Materials, Bayreuth Engine Research Center (BERC), University of Bayreuth, 95440 Bayreuth, Germany"}]},{"given":"Andreas","family":"Heinrich","sequence":"additional","affiliation":[{"name":"Functional Materials, Bayreuth Engine Research Center (BERC), University of Bayreuth, 95440 Bayreuth, Germany"},{"name":"Engineering Thermodynamics and Transport Processes, Bayreuth Engine Research Center (BERC), University of Bayreuth, 95440 Bayreuth, Germany"}]},{"given":"Dieter","family":"Br\u00fcggemann","sequence":"additional","affiliation":[{"name":"Engineering Thermodynamics and Transport Processes, Bayreuth Engine Research Center (BERC), University of Bayreuth, 95440 Bayreuth, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6960-9805","authenticated-orcid":false,"given":"Ralf","family":"Moos","sequence":"additional","affiliation":[{"name":"Functional Materials, Bayreuth Engine Research Center (BERC), University of Bayreuth, 95440 Bayreuth, Germany"}]}],"member":"1968","published-online":{"date-parts":[[2010,3,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"27","DOI":"10.1595\/147106709X390977","article-title":"Cleaning the air we breathe\u2014Controlling diesel particulate emissions from passenger cars","volume":"53","author":"Twigg","year":"2009","journal-title":"Platin.
