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 …

Meeting cold-start emissions standards for particulate emissions and the criteria air
pollutants, NO, CO and unburned hydrocarbons (HC), is critical for gasoline direct-injection …

Biomass-burning organic-aerosol (OA) emissions are known to exhibit semi-volatile
behavior that impacts OA loading during plume transport. Because such semi-volatile …

Air pollution is a severe threat to public health globally, affecting everyone in developed and
developing countries alike. Among different air pollutants, particulate matter (PM) …

We assessed the gaseous, particulate, and genotoxic pollutants from two current technology
gasoline direct injection vehicles when tested in their original configuration and with a …

Fast-sizing spectrometers, such as the TSI Engine Exhaust Particle Sizer (EEPS), have been
widely used to measure transient particle size distributions of vehicle exhaust. Recently, size …

Density (ρ) is one of the most important physical properties of aerosol particles. Owing to the
complex nature of aerosols and the challenges of measuring them, effective density (ρ e) is …

A gasoline particulate filter (GPF) is an effective wall-flow technology for gasoline engine
particulate matter (PM) emission control via deep-bed filtration through porous ceramic walls …

We assessed the physical, chemical and toxicological characteristics of particulate
emissions from four light-duty gasoline direct injection vehicles when operated over the …

Sensors for in situ detection of aerosols using conventional optical scattering methods
generally fail to identify the types and sources of particles, and they even have a large …
