Heavy-duty emissions inventory and prediction
Heavy duty vehicle emissions represent a significant portion of the mobile source emissions inventory. Accurate estimation of their contribution is essential as on-highway and non-road heavy duty diesel emissions account for at least one third of the oxides of nitrogen (NOx) in the inventory. West …

Simulation of heavy-duty hybrid electric vehicles
… used to simulate the driving conditions of heavy-duty hybrid electric vehicles over various driving cycles in an attempt to optimize their design and control. The fuel economy data thus obtained were compared with those of the in-use heavy-duty hybrid electric vehicles. For this the drive cycles …
