EPA’s charge from the NEPD included exploring ways to increase the flexibility in the distribution infrastructure, improve fungibility, and provide added gasoline market liquidity. In addition to looking at distribution system impacts, EPA analyzed how the various options could affect the overall supply of gasoline from refineries in the U.S. (i.e., gasoline production capacity). Analyzing the ...

The phaseout of leaded gasoline would be a significant step forward in the reduction of a major source of exposure; however, this undertaking , even if successful, will have limited public health impact if other sources of exposure are not substantially reduced. For instance, in Mexico City, after the introduction of unleaded gasoline in 1990, lead concentrations in air declined from 1.2 pg/m3 ...

The driving behavior, road, and traffic conditions greatly affect the gasoline consumption of an automobile. We believe that accurate prediction of gasoline usage as a function of the above can be used to obtain optimal driving behavior, for given road and traffic conditions, to reduce gasoline consumption. This results in great dollar savings and also reduces the harmful effects of gasoline us...

The Gas to Gasoline (GTG) process includes conversion of natural, flare, and associated gas into synthetic fuels that can be compositionally upgraded and adjusted into different useful hydrocarbon fuels including gasoline, liquid petroleum gas (LPG), and fuel gas. Commonly, the GTG process involves three stages: 1) Synthesis gas (syngas) production unit 2) Methanol production unit 3) Methanol t...

This paper proposes a method of distinguishing between the effect of anticipated and unanticipated changes in oil prices and oil inventories on the US gasoline prices. I show that gasoline price adjustments are faster and stronger for anticipated changes in oil prices and inventory levels than for unanticipated changes. The dynamics of the gasoline price response depends on the relative importa...

The invention of the spark-ignited internal combustion engine provided a market for a petroleum middle distillate, gasoline, about 100 years ago. The internal combustion engine and gasoline have co-evolved until motor vehicles now annually consume about 110 billion gallons of gasoline in the United States. Continuing air pollution problems and resulting regulatory pressures are driving the need...

A National Fuels Surveillance Network has been established to collect gasoline and other fuels through the 10 regional offices of the Environmental Protection Agency. Physical, chemical, and trace element analytical determinations are made on the collected fuel samples to detect components which may present an air pollution hazard or poison exhaust catalytic control devices. A summary of trace ...

Concerns about energy security and climate change have sparked legislators’ interest in reducing gasoline consumption by increasing corporate average fuel-economy (CAFE) standards. Using an empirically rich simulation model and cost estimates for anticipated fuel-economy technologies, we estimate annual costs of reducing long-run gasoline consumption by 10% via a 3.8 miles per gallon increase i...

The influences of gasoline on the emission of polycyclic aromatic hydrocarbons (PAHs) from gasoline engine are investigated. These fuels included C92-Leadfree Gasoline (C92-LFG), C95-Leadfree Gasoline (C95-LFG), C98-Leadfree Gasoline (C98-LFG), these are Reforming Gasoline, T92-Leadfree Gasoline (T92-LFG), T95-Leadfree Gasoline (T95-LFG), T98-Leadfree Gasoline (T98-LFG), these are total-PAHs co...

The tests were carried out with the spark timing adjusted to the maximum brake torquetiming in various equivalence ratios and engine speeds for gasoline and natural gas operations. In thiswork, the lower heating value of gasoline is about 13.6% higher than that of natural gas. Based on theexperimental results, the natural gas operation causes an increase of about 6.2% brake special fuelconsumpt...
