The introduction discusses the subject of optical measurement methods and refers to Lambert Beer's law describing the phenomenon of absorption of electromagnetic radiation when passing through a partially absorbing and scattering medium. The vehicle used during the tests was characterized by a four-cylinder drive unit with a maximum power of 110 kW at 4000 rpm and a maximum torque of 320 Nm at 2000 rpm.

During the measurements, concentrations of harmful exhaust gas compounds were analyzed in relation to the distance of the measuring probe from the exhaust system.

The tests carried out show that the concentrations obtained behind a moving vehicle significantly decrease with the distance of the measuring probe, and their dispersion in most cases is much smaller than in the case of stationary tests.
