The widespread use of methyl tert-butyl ether (MTBE) as a gasoline additive has resulted in a large number of cases of groundwater contamination. Bioremediation is often proposed as the most promising alternative after treatment. However, MTBE biodegradation appears to be quite different from the biodegradation of usual gasoline contaminants such as benzene, toluene, ethyl benzene and xylene (B...

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...

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...

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...

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 ...

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...

Methyl tertiary butyl ether (MTBE), a well known gasoline additive, is used in China nationwide to enhance the octane number of gasoline and reduce harmful exhaust emissions, yet little is known regarding the potential health risk associated with occupational exposure to MTBE in petrol stations. In this study, 97 petrol station attendants (PSAs) in southern China were recruited for an assessmen...

Biofuel is an option to reduce CO2 generated by vehicles. In this study, synthetic crude furfural from cassava stems was blended as fuel additive gasoline (Pertalite) and then induced electromagnetic field. Analysis were carried out on engine performance exhaust emissions produced Kohler engines. Variations formed samples commercial (C5H4O2), time variations of induction for 0 30 minutes. The b...

Manganese is a potent environmental toxin, with significant effects on human health. Manganese exposure is of particular concern in South Africa where in the last decade, lead in gasoline has been replaced by methylcyclopentadienyl manganese tricarbonyl (MMT). We investigated recent historical levels of manganese exposure in urban Gauteng, South Africa prior to the introduction of MMT in order ...
