We present UNREAL project, funded by the french research agency. The main objectives of this project are: 1) To determine the mechanism behind vPM formation in the engine exhaust and if there is a link with fuel composition 2) To establish a sampling protocol for vPM measurements that can be used in certification processes 3) To determine the impact of fuel chemical composition on the physico-chemical properties of vPM and nvPM
