Reframing Automotive Fuel Efficiency

SAE International Journal of Sustainable Transportation, Energy, Environment, & Policy, 2020
<div>Electric powertrains’ astounding recent progress often eclipses comparable energy-saving potential from aggressively reducing tractive load, especially by ambitious lightweighting. Both strategies are valid and important, but their diverse benefits—transcending simple competition ...

Efficient multicomponent fuel algorithm

Combustion Theory and Modelling, 2003
We derive equations for multicomponent fuel evaporation in airborne fuel droplets and wall films, and implement the model into KIVA-3V. Temporal and spatial variations in liquid droplet composition and temperature are not modelled but solved for by discretizing the interior of the droplet in an implicit and computationally efficient way.

The transport energy trade-off: Fuel-efficient traffic versus fuel-efficient cities

Transportation Research Part A: General, 1988
Improving fuel efficiency in vehicular traffic by increasing average speeds is shown to have a major trade-off through land use changes and modal shifts that result in an overall loss in fuel efficiency for the total urban area. In Perth, even though vehicles in central areas have a 19% lower fuel efficiency than average due to congestion, the central ...
