Vehicle regulations include limits for non-volatile particle number emissions with sizes larger
than 23 nm. The measurements are conducted with systems that remove the volatile …

Vehicles' exhaust particulate matter (PM) emissions have significantly decreased over the
years. On the other hand, non-exhaust emissions, ie, particle emissions from brakes and …

The particle number (PN) emissions of vehicles equipped with particulate filters are low.
However, there are technologies that can have high PN levels, especially below the …

Particulate mass concentration is a crucial parameter for characterising air quality. The
diesel particulate filter (DPF) is the primary technology used to limit vehicle particle …

Solid particle number vehicle exhaust measurements necessitate an aerosol conditioning
system that removes efficiently volatile particles, does not create artifacts, and minimizes …

Nowadays, the regulation regards only the particles larger than 23 nm. The attention is
shifting towards the sub-23 nm particles because of their large presence at the exhaust of …

The bridge structure inside porous wall is an important feature in diesel particulate filter
(DPF) functionality. In this work, the formation process of bridge structure is simulated for the …

Particulate emissions from on-road motor vehicles are the focus of intensive current
research due to the impact of the ambient particulate matter (PM) levels on climate and …

In order to describe the microstructure of the porous wall of a gasoline particulate filter
(GPF), a pore size distribution based on a probability density function (PDF) and a non …

The research on health effects of soot particles has demonstrated their toxic impact on
humans, especially for the smallest ones that can pass through the lungs into the …
