Description

This data set includes measurement data from laboratory engine experiments where different fuel types and exhaust wets scrubbing was investigated for their impact on engine exhaust particle formation. Data includes information on particle number size distributions, effective densities, chemical characterization, hygroscopicity and ice nucleation activity of exhaust particles.

Data collection

Mode of collection: Experiment
Description of the mode of collection: Diesel engine exhaust particle data were collected using a range of on-line aerosol instrumentation, including a SMPS, AAC, CCN and a CFDC, and off-line instruments for chemical characterization (STXM and NEXAFS).
Time period(s) for data collection: 2022-05 – 2022-06
Instrument: AAC (Technical instrument(s)) - Aerodynamic Aerosol Classifiers (AAC) are used to select particles by their aerodynamic diameters.
Instrument: SMPS (Technical instrument(s)) - Scanning Mobility Particle Sizer measure particle size distributions.
Instrument: CFDC (Technical instrument(s)) - Continuous Flow Diffusion Chambers (CFDC) measure ice crystal formation of aerosol particles.
Instrument: CCNc (Technical instrument(s)) - Cloud Condensation Nuclei Counter (CCNc) can measure the liquid droplet activation of aerosol particles.
