The addition of ethanol into gasoline has long been a method to help the hydrocarbons of gasoline burn smoother in an internal combustion engine by adding oxygen into the fuel. Gas stations list ethanol content in gasoline can be up to 10% ethanol but no more than 10% ethanol. By using the methods of standard addition, using known concentrations and volumes of spikes of ethanol into the gasolin...

Since 1970, vehicle’s exhaust pollutions have received increasing attention as a source of air pollution at both local (human health concerns) and global (global warming) scales. This study mainly discusses diesel and gasoline vehicles because, today, over 90% of vehicles on the road use gasoline and diesel fuels. The major concerns of gasoline exhaust contaminants are carbon monoxide (CO), hyd...

Biodiesel combustion in diesel engines is associated with reduced carbon monoxide, particulate matter and unburned hydrocarbons emissions, but several concerns remain including deposition, low thermal efficiency elevated nitrogen oxides production. To this end, the incorporation of gasoline additive has been proposed as a solution to drawbacks posed by biodiesel. Integrated chemical kinetics-co...

Methyl-tert-butyl ether (MTBE) is a commonly used gasoline additive. Leaking underground storage tank systems, spills, and pipeline failures are the causes of reported groundwater contamination with MTBE. The impact of vegetation on MTBE plume transport in groundwater and volatilization was experimentally examined. The experimental system consists of six channels, five of which are planted with...

Ethanol use in vehicle fuel is increasing worldwide, but the potential cancer risk and ozone-related health consequences of a large-scale conversion from gasoline to ethanol have not been examined. Here, a nested global-through-urban air pollution/weather forecast model is combined with high-resolution future emission inventories, population data, and health effects data to examine the effect o...

Increasing numbers of young women are employed as gasoline station attendants in most developing countries despite the lack of empirical data on the adverse reproductive health effect of this solvent. This study therefore sought to assess the effects of gasoline inhalation on the serum sex hormone profile and menstrual characteristics of female gasoline station attendants in Nigeria, given the ...

Imagine a world where government regulation of gasoline, justified by scarcity of supply, allowed 20% of the gasoline in the U.S. to be used for farming; 20% for manufacturing; 20% for home use; 20% for government; and another 20% held in reserve for future potential government uses. In this world, prices would regulate the use of gasoline within each sector, but consumers would pay vastly diff...

This paper applies artificial neural networks to forecast gasoline consumption. The ANN is implemented using the cross entropy error function in the training stage. The cross entropy function is proven to accelerate the backpropagation algorithm and to provide good overall network performance with relatively short stagnation periods. To forecast gasoline consumption (GC), the ANN uses previous ...

The present investigation mainly focuses on overcoming the limitations of gasoline fumigation (GF) in diesel engines by adding up nano fuel additives. Experiments are conducted to ascertain engine working characteristics a single-cylinder, four-stroke using aluminum oxide (Al2O3) additives blended as main injection along with GF an inducted fuel. was achieved controlling electronic injector fit...

Since 1999, gasoline prices in California, Illinois and Wisconsin have spiked occasionally well above gasoline prices in nearby states. In May and June 2000, for example, gasoline prices in Chicago rose twenty eight cents per gallon to $2.13, while prices nationally rose only nine to $1.73. Several qualitative studies identify unique gasoline formulations in California, Illinois and Wisconsin a...
