Measurement of particulate matter size, concentration and mass emissions from in-use heavy duty vehicles

As technological advancements lower heavy duty vehicle particulate matter (PM) mass emission rates, there is concern that these improvements are increasing the toxicity of the PM by virtue of a subsequent reduction in particle size. These ultrafine particles are able to better penetrate the alveolar region where they can cause serious lung disorders. Alternative fuels such as compressed and liquefied natural gas (CNG and LNG) and the synthetic diesel fuel Mossgas are attractive in that they reduce the levels of total PM. However, use of natural gas in internal combustion engines may produce a larger number of smaller particles than commercial diesel fuel, and little particle size information is available on Mossgas combustion.;The tests showed the effectiveness of the measurement system while returning mass and size data for the various fleets. The particulate measurement system allowed this full description of particle emissions to be performed quantitatively rather than mathematically.
