| Zusammenfassung | Combustion particles must be monitored closely because of their role in climate change and their adverse health effects. Modern combustion engines emit small particles with negligible mass, but still at high number concentrations. The conventional metric, particle mass (PM) concentration fails to measure correctly the particle load in the exhaust gas. There is a need for a new metric, particle number (PN) concentration, and novel portable PN-measuring instruments suitable for tests directly at the vehicle tailpipe. European countries have recently started to develop new PN-based technical inspection procedures for vehicles. However, the lack of standardization/harmonization causes confusion among end-users and has to be urgently addressed. |
