When determining the emission of detrimental pollutants in the exhaust gases, most problems are caused by the measurement of the amount of particulates emitted by diesel engines. The measurement methodology which is being currently used is determined by international regulations of EPA, ISO and ECE - R49, accepted more than 10 years ago. This methodology requires a special test stand equipped with a tunnel diluting the exhaust gases and simulating the real condition of mixing the exhaust gases with the atmospheric air. The levels of particulates emission are evaluated gravimetrically, by the accurate weighing of the particles filtered out from a sample of mixture taken in the tunnel. The construction of the test stand as well as the measurement conditions are defined in the aforementioned regulations. However, there are several important details associated with the test methodology which have not been defined precisely in the regulations or which may be adjusted freely. Such a situation reduces the possibilities of comparing the results of tests conducted in different test centres, the repeatability of test results and their objectivity. These factors are very important during engine tests (e.g. type approval tests) measuring the emission of particulates and during research and development studies. One of such imprecisely defined test conditions is the conditioning of filters used in the particulates emission tests. This issue is discussed in this paper, which is based on the tests conducted by the authors at the Cracow University of Technology.
