Emissionsmätningar från bussar: Euroklass VI-gasbussar och bränsledrivna värmare i elbussar

Abstract [sv]

Inom ramen för ett forskningsprojekt, samfinansierat av Västtrafik och Stiftelsen IVL, har emissionerna från individuella Euroklass VI-gasbussar samt bränsledrivna värmare i elbussar karakteriserats, totalt 37 st. (20 gasbussar och 17 värmare).

En extraktiv mätmetod har använts där omgivningsluften kontinuerligt provtas och koncentrationerna av både gaser och partiklar mäts med hög tidsupplösning (≥1 Hz).

Emissionsfaktorer (EF) beräknas genom att använda kolbalansmetoden, där fullständig förbränning och en viss kolfraktion i bränslet antas. Resultaten rapporteras som föroreningarnas massa (alt. antal) per kilo förbrukat bränsle. 

Abstract [en]

Within the frame work of a research project funded by Västtrafik and the foundation SIVL, the emissions from individual Euro class VI gas buses and fuel-operated heaters in electric buses have been characterised, in total 37 buses (20 gas buses and 17 heaters).

An extractive measurement method has been used where the ambient air is continuously measured, and particle and gaseous concentrations are measured with high time resolution (≥1 Hz).

Emission factors (EFs) were retrieved using the carbon balance method, assuming complete combustion and a specific fuel carbon content. The results are reported as mass or number of pollutants per kilo fuel burnt.
