The paper presents results of tests on particulate matter (PM) in PC and HDV category vehicles fitted with compression ignition engines and various systems of exhaust gas aftertreatment. The measurements were made under actual conditions of use in a city and used portable exhaust gas analyzers belonging to a group of PEMS (Portable Emissions Measurement Systems) – AVL MSS concentration analyzer and TSI EEPS mass spectrometer. The obtained results were processed and coefficients of correlation were determined for PC-PC and PC-HDV. The considerations were made according to Euro 3-5 emission standards. Moreover, the paper discusses a scheme of soot and PM formation as well as describes the influence of exhaust gas aftertreatment systems upon formation of the same. Keywords: ecology, exhaust emissions, particulate matter.
