The analysis of dynamic real traffic conditions of combustion engines can be reduced to the analysis of a given parameter with the following coordinates: vehicle speed – vehicle acceleration. Such a definition is similar to the analysis of the static characteristics of engines using coordinates of engine speed – engine load. If the whole vehicle with its drive unit is to be treated as a ‘closed object’ (a so-called black box), then the adoption of such an assumption allows for an analysis of the selected parameters of particulate matter, regardless of the internal changes taking place within the unit under consideration. This assumption does not preclude the simultaneous collection of data on the operation of the drive unit (such as engine speed and engine load from the OBD system [3, 4, 6, 11, 23, 36]).
