Summary

In the applied models of total exhaust emissions from transport, the emission rate is adopted based on maximum admissible values prescribed in an exhaust emission homologation standard. In such a scenario, the results obtained from the models are only estimates, whose applicability may be restricted. It is thus necessary to seek new possibilities to assess vehicle exhaust emissions such as real-driving measurements. The measurements are performed under vehicle actual operating conditions and they use the PEMS (Portable Emission Measurement System) equipment. The research carried out at Poznan University of Technology with the use of this method attempts to answer questions regarding the exhaust emissions, their variability and relation to the engine and vehicle operating parameters.
