Abstract Despite that Heavy-Duty Vehicles (HDVs) represent a small part of the overall
vehicle population they have been identified as one of the most important contributors to air …

Emissions from thousands of in-use heavy-duty diesel trucks were sampled at a highway
and an arterial street location in the San Francisco Bay Area, spanning a time period when …

As the push to reduce air pollutants and carbon dioxide for global warming continues, there
is increasing interest in the development and deployment of battery electric vehicles for …

The transition, in extent and characteristics, of atmospheric emissions caused by the
modernization of the heavy-duty on-road fleet was studied utilizing roadside measurements …

Trackless rubber-tyred vehicles are among the most widely used underground auxiliary
transportation equipment in major coal mines at present. The migration of exhaust gas that …

Purpose Underground diesel exhaust exposure is an occupational health risk. It is not
known how recent intensified emission legislation and use of renewable fuels have reduced …

The implementation of a comprehensive heavy-duty vehicle (HDV) Inspection and
Maintenance (I/M) program could be a critical element in ensuring the emission control …

Traditionally, vehicle emissions measurements rely on reference-grade instruments whose
high cost and complexity have limited their deployment in real-world environments. New …

High-emission vehicles (high emitters) likely have significantly higher nitrogen oxide and
particle number (PN) emission factors compared to other vehicles. Effective identification of …

Technological advances in heavy-duty vehicle engines, allowing them to reach NO x
emissions comparable to European diesel passenger cars per km driven, are being …
