Can Vehicle Efficiency Beat Fuel Efficiency in Cutting Fuel Use? [PDF]

open access: yes, 2018
This paper demonstrates the importance of considering both energy and non-energy efficiency improvements in the provision of energy intensive household services. Using the example of private transport, we analyse whether vehicle efficiency can beat fuel efficiency in cutting fuel use.

Framing car fuel efficiency: linearity heuristic for fuel consumption and fuel-efficiency ratings [PDF]

open access: yesEnergy Efficiency, 2014
People are sensitive to the way information on fuel efficiency is conveyed. When the fuel efficiency of cars is framed in terms of fuel per distance (FPD; e.g. l/100 km), instead of distance per units of fuel (DPF; e.g. km/l), people have a more accurate perception of potential fuel savings.

Design of experiment study of the parameters that affect performance of three flow plate configurations of a proton exchange membrane fuel cell [PDF]

open access: yes, 2010
Low temperature hydrogen fuel cells are electrochemical devices which offer a promising alternative to traditional power sources. Fuel cells produce electricity with a reaction of the fuel (hydrogen) and air. Fuel cells have the advantage of being clean;

Automotive Fuel Efficiency [PDF]

open access: yesScience, 1992
For at least the remainder of this century, the United States faces a growing dependence on imported oil. Costs are substantial, and they will mount. In June 1992, net imports provided nearly 50% of supplies, and their cost was $4.3 billion. Cost of net imports of motor vehicles and parts amounted to $3.0 billion.

Fuel-Efficient Trajectories Traffic Synchronization [PDF]

open access: yesJournal of Aircraft, 2019
Continuous descent operations (CDOs) with required times of arrival (RTA) have been identified as a potential solution for reducing the environmental footprint of aviation in the terminal maneuvering area without compromising capacity. This paper assesses the feasibility of replacing current air traffic control sequencing and merging techniques, mainly

Evaluation of the micro-carburetor [PDF]

open access: yes, 1981
A prototype sonic, variable-venturi automotive carburetor was evaluated for its effects on vehicle performance, fuel economy, and exhaust emissions.

Fuel Efficiency of Small Aircraft [PDF]

open access: yesJournal of Aircraft, 1980
There is a basic mismatch between the amount of power installed in small propeller-driven aircraft and that required for efficient cruising, which results from climb performance requirements. It is shown in this paper that there is a way of using excess power for most efficient cruise, the resulting airspeed coming closest to the Gabrielli-von Karman ...

Efficient Combination of Taxes on Fuel and Vehicles [PDF]

open access: yesThe Energy Journal, 2018
A tax on fuel combined with tax exemptions or subsidies for fuel-efficient vehicles is implemented in many countries to reduce greenhouse gas emissions and other negative externalities from road traffic. This study, however, shows that a tax on fuel should be combined with heavier taxation of fuel-efficient vehicles to curb externalities from road ...

Efficient Taxation of Fuel and Road Use [PDF]

open access: yesSSRN Electronic Journal, 2019
This study calculates efficient taxes on fuel and road use designed to combat driving related externalities. The study shows that the efficient road user charge on fuel is below the marginal mileage-related damage to prevent tax avoidance due to an excessive economic driving-style. The current US tax rate on gasoline is way below the efficient tax rate
