This review article summarizes major and representative developments in vehicle emissions
regulations, engine efficiency, and emission control from 2017. The article starts with the key …

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 …

To improve ambient air quality, several countries have adopted regulations setting stringent
limits on vehicular tailpipe emissions of particulates. The issue of high particulate emissions …

Road transport significantly contributes to air pollution in cities. Emission regulations have
led to significantly reduced emissions in modern vehicles. Particle emissions are controlled …

With increasing road and non-road vehicles in use, air quality and human health have been
under greater pressure in recent years. Generally, changes involving aerosol-based …

The dynamic development of transport in recent decades reflects the level of economic
development in the world. The transport sector today is one of the main barriers to the …

Increasingly stringent particulate matter (PM) emission standards have brought forth engine
design improvements, cleaner-burning fuels, and aftertreatment technologies. Reductions in …

As the measurement of low levels of particulate matter (PM) and solid particulate number
(PN) from light-duty vehicles becomes more critical, it is becoming more important to …

Recently, there are discussions about whether current sampling and measurement practices
for the regulated gravimetric PM measurement are sufficiently accurate in quantifying PM at …

In recent years, gasoline direct injection (GDI) engines have been widely used by
manufacturers in light-duty to meet stringent fuel economy and emissions standards. This …
