Pollutant emissions need to be accurately estimated to ensure that air quality plans are
designed and implemented appropriately. Emission factors (EFs) are empirical functional …

Accurate estimations and assessments of vehicle emissions can support decision-making
processes. Current emission estimation tools involve several calculation methods that …

Background Traffic congestion is a significant issue in urban areas in the United States and
around the world. Previous analyses have estimated the economic costs of congestion …

We calculated carbon and energy balances and costs of 14 different Fischer–Tropsch (FT)
fuel production plants in 17 complete well-to-wheel (WTW) chains. The FT plants can use …

Euro 6-compliant diesel passenger cars have tended to feature lean NO x traps (LNTs) to
satisfy the increasingly stringent NO x regulations. This paper focused on NO x emission …

Emissions during a trip often depend on transient vehicle dynamics that influence the
instantaneous engine load. Vehicle specific power (VSP) is a proxy variable for engine load …

A fuel-based approach is used to assess long-term trends (1970–2010) in mobile source
emissions of black carbon (BC) and organic aerosol (OA, including both primary emissions …

Fuel-based emission factors for 143 light-duty gasoline vehicles (LDGVs) and 93 heavy-duty
diesel trucks (HDDTs) were measured in Wilmington, CA using a zero-emission mobile …

The chemical compositions of PM 2.5 including OC, EC, water soluble ions, elements, and
organic components such as polycyclic aromatic hydrocarbons (PAHs), hopanes, and …

Dual fuel low temperature combustion (LTC) strategies are attractive for future internal
combustion engines due to their promise of very low engine-out emissions of oxides of …
