Due to the nitrogen oxide (NOx) sensor's cross-sensitivity and inability to monitor ammonia
coverage, it is critical to eliminate these flaws for a significant percentage of in-use diesel …

Vehicle loads have significant impacts on the emissions of heavy-duty trucks, even in the
same traffic conditions. Few studies exist covering the differences in emissions of diesel …

Vehicle exhaust, an important source of air pollution, is affected by many factors, including
driving conditions, combustion efficiencies, and the usage of emission control devices. In …

Nitrogen dioxide (NO2) is a common urban air pollutant that is associated with several
adverse human health effects from both short and long term exposure. Additionally, NO2 is …

The latest generation of heavy-duty vehicles (Euro VI step E) have to respect low emission
