Particulate Matter (PM) emissions from gasoline direct injection (GDI) engines, particularly
Particle Number (PN) emissions, have been studied intensively in both academia and …

Particles endanger the ecosystem and human health in a significant way. Currently, under
strict emission regulations, optimizing fuel and combustion systems is no longer enough …

ABSTRACT Globally, 1.3 billion on-road vehicles consume 79 quadrillion BTU of energy,
mostly gasoline and diesel fuels, emit 5.7 gigatonnes of CO2, and emit other pollutants to …

This study assessed the real-world emissions from two heavy-duty natural gas vehicles
certified to the optional 0.02 g/bhp-hr nitrogen oxides (NOx) standard and one diesel vehicle …

Gaseous fuels, eg, natural gas, biogas, have several advantages over liquid fuels owing to
their favorable physical and chemical properties, eg, lower carbon numbers in the fuel …

In comparison to legacy engine technology, natural gas vehicles have become cleaner and
more efficient. Improved fueling infrastructure has supported the growth of natural gas …

This study assessed the real-world nitrogen oxide (NOx) and black carbon emissions from
six goods movement heavy-duty diesel and compressed natural gas (CNG) vehicles …

In view of the strong interest in the adoption of hydrogen as an alternative fuel for internal
combustion engines, the authors present the results of an experimental activity aimed at …

Emissions were measured from seven heavy-duty (HD) on-road vehicles that were operated
along six common route types used for freight transport in California. All vehicles had …

The gaseous and particulate matter (PM) emissions from three heavy-duty natural gas
vehicles, including a lean-burn bus with an oxidation catalyst and two stoichiometric Class 8 …
