| Abstract: | In order to satisfy the requirement of the diesel particulate filter safe using,an on line measurement technology of measuring diesel particulate accumulation in a filter has been developed.The composition and the principle of the instrument is given and some factors affecting the measurement result are analyzed.The results of study show that this measurement method is inherently independent of gas volumetric flow rare and is relatively insensitive to changes in filter temperature.This technology can be used to measure diesel particulate accumulation in a ceramic filter continually and have certain practical value. |
