The particulate matter (PM) emissions of gasoline vehicles were much lower than those of
diesel vehicles until the introduction of diesel particulate filters (DPFs) in the early 2000s. At …

Abstract Hydrocarbons, CO, NOx, NH 3, N 2 O, CO 2 and particulate matter emissions affect
air quality, global warming and human health. Transport sector is an important source of …

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 …

Light-duty vehicle emission regulation in the European Union requires the dilution of the
whole exhaust in a dilution tunnel with constant volume sampling prior to emission …

Particulate matter (PM), and in particular ultrafine particles, have a negative impact on
human health. The contribution of vehicle PM emissions to air pollution is typically quantified …

ABSTRACT A solid particle number limit was applied to the European legislation for diesel
vehicles in 2011. Extension to gasoline direct injection vehicles raised concerns because …

A detailed experimental characterization of the particle emissions of a EURO 5 light-duty
Diesel engine, equipped with a wall flow Diesel Particulate Filter (DPF), is presented …

The solid particle number method was introduced in the European Union (EU) light-duty
legislation for diesel vehicles to ensure the installation of the best-available technology for …

Abstract Ultrafine (< 100 nm) particles related to traffic are of high environmental and human
health concern, as they are supposed to be more toxic than larger particles. In the present …

Abstract The European Commission is planning to lower the particle cut off size down to 10
nm to consider the contribution of the sub-23 nm particles. Within the European project …
