Over the past few decades, criteria emissions such as carbon monoxide (CO), hydrocarbons
(HCs), nitrogen oxides (NOx) and particulate matter (PM) from transportation have …

The rate of increase in greenhouse gas concentrations in the atmosphere has already
reached a critical point. Day by day, the number of vehicles on the road is increasing in a …

The significant impact of low ambient temperature, which was less regulated, on vehicle
exhaust emissions had garnered considerable attention. This study investigated the impact …

The uneven temperature field, flow field, and internal low temperature of the catalytic

Enhancing gasoline detergency is pivotal for enhancing fuel efficiency and mitigating
exhaust emissions in gasoline vehicles. This study investigated gasoline vehicle emission …

In this study, we analyzed particle emission characteristics in the engine restart (ER) phase
of a hybrid electric vehicle (HEV) based on driving characteristics and ambient temperature …

Traffic as an important part of the energy sector significantly contributes to global air
pollution. To mitigate the hazardous components of traffic emissions regulations have been …

Brown carbon (BrC), as an important light-absorbing aerosol, significantly impacts regional
and global climate. Vehicle emission is a nonnegligible source of BrC, but the optical …

Abstract Light-absorbing aerosols (LAA), including black carbon (BC) and brown carbon
(BrC), profoundly impact regional and global climate. Vehicle emission is an important …
