- A new method of measuring diesel-particulate accumulation has been developed that uses electromagnetic energy to interrogate a ceramic filter and to give a real-time measurement of the trapped-soot level. The measurement method is inherently independent of engine-exhaust-gas volumetric flow rates and is relatively insensitive to changes in filter temperature.This paper presents laboratory data, derived from testing of full-scale, wall-flow filter systems, demostrating the viability of the measurement method. The implementation of the measurement method in on-vehicle regeneration system is also discussed.
