Résumé
A large fraction of the total number of particles emitted by direct injection engines are below the adopted 23 nmdiameter threshold and although the EU aims to regulate these emissions, this is not yet possible due to the absenceof accurate and reliable quantification methods, especially under real driving conditions. Four researchorganisations, three particle measurement instrumentation companies and one automotive OEM have joined forcesin the framework of the EU-funded project SUREAL-23 to overcome such barriers by introducing noveltechnology for the measurement of sub-23 nm exhaust particle concentration, size and composition. The mainobjectives of SUREAL-23 are to (a) simplify and make more robust the exhaust aerosol sample treatment, (b)elucidate the effect of different diesel and gasoline engine operating conditions on sub-23 nm particle emissionsand (c) advance particle measurement technology with the introduction of novel techniques. Herein, we presentour latest efforts on instrumentation development and aerosol sampling.
