On efficient utilization of fuels
Energy, 1982Abstract Various methods are developed to conserve fuels by increasing the efficiencies of heat engines. These efforts are limited by fundamental constraints on efficiency, as specified by the Carnot engine. We consider a cyclic process during which heat is converted into work while no other body, except the atmosphere, acts as both the source and ...

Fuel-efficient navigation in complex flows
2008 American Control Conference, 2008In realistic time-chaotic flows, the time-dependent separatrices are revealed by Lagrangian coherent structures (LCS). The LCS surfaces organize complex flows, revealing dynamical channels useful for weakly propelled mobile agents. We propose a feedback control strategy to explicitly incorporate LCS, which are in general evolving. Inane et al.

Consumers have been slow to switch to more fuel efficient vehicles, in spite of the threat of a future global shortage of fossil fuels. To understand consumer reluctance to adopt hybrid automotive technology, this chapter begins by reviewing consumer decision-making with regard to consumer automotive purchases.

Development and Testing of Fuel-Efficient Fuel Additive
SAE Technical Paper Series, 1985<div class="htmlview paragraph">This paper describes the physical properties and chemical components of a new fuel additive package along with various testing procedures used in the development of the product. It describes the use of the Fuel Economy Engine Oil Test procedure in determining the relative fuel economy effects of the additive.

Theoretical and Natural Science
Selecting a chemical propellant for a launch vehicle isn't just about looking up specific impulse values in a handbook. Vacuum I_{sp} matters a great deal for upper stages, obviously, but for a reusable booster that has to fly again next week, a bunch of other considerations start to dominate.

The Efficiency of Domestic Solid Fuel Appliances
Journal of the Royal Sanitary Institute, 1953The measurement cf the efficiency with which a domestic appliance burning solid fuel utilizes its fuel is not an easy matter. Moreover, many British types of appliance, notably the open fire, form an integral part of the structure of the house ; the true efficiency is therefore not a simple function of the appliances itself, but is dependent both on ...

Are Consumers or Fuel Economy Policies Efficient?
2008This chapter describes how recent increases in oil prices, concern about energy security, and apprehension over global climate change have turned attention to fuel economy policy in the United States (U.S.). The primary mechanism to reduce oil use in the U.S. is the set of corporate average fuel economy (CAFE) standards. Paralleling current concerns of
