Abstract in another language

Diesel particulate filters (DPF) are essential for diesel exhaust gas aftertreatment in the automotive sector. For soot load determination, a novel approach using microwaves emerged recently. Based on the electrical conductivity of soot particles, the soot load of the DPF can be measured directly and in a contactless way by this method. Microwaves are impressed into the filter housing and the reflection and transmission is measured. In this study, in-operation dynamometer measurements are presented. Tests of filter loading at constant operation conditions as well as engine speed and load variations at constant soot load were conducted. The results obtained from weighed soot mass, differential pressure signals, and the microwave data agree well. Soot load determination with the microwavebased method is possible. A clear dependency of temperature needs to be corrected, whereas exhaust gas mass flow seems to have no notable influence.
