On-road and laboratory evaluation of combustion aerosols-Part1: Summary of diesel engine results
TLDR
In this paper, on-road emissions from four, heavy-duty diesel truck engines were measured and the same engines were reevaluated in the manufacturers' laboratories, showing that nuclei mode particles consisted mainly of heavy hydrocarbons.About:

Simulation of particle size distribution with a global aerosol model: contribution of nucleation to aerosol and CCN number concentrations
Fangqun Yu,Gan Luo +1 more
TL;DR: In this paper, an advanced particle microphysics model with a number of computationally efficient schemes has been incorporated into a global chemistry transport model (GEOS-Chem) to simulate particle number size distributions and cloud condensation nuclei (CCN) concentrations in the atmosphere.

Engines and nanoparticles: a review
TL;DR: In this article, a new HEI study showed that some low-emission diesel engines emit much higher concentrations of nanoparticles than older designs and other low-EMission designs, which has raised questions about whether nanoparticle (number based) emission standards should be imposed.
