Pumping oxygen into gasoline
To reduce atmospheric concentration of certain pollutants notably carbon monoxide (CO), incompletely combusted hydrocarbons and nitrogen oxides (NOx), EPA as early as January 1988 began testing oxygenated fuels in such cities as Denver and Albuquerque, N.M. The CAA Amendments require using oxygenated gasoline in cities where CO levels exceed National Ambient Air Quality standards. The law, which became effective Nov. 2, affects about 40 urban areas during the winter, when CO levels are higher. Methyl tertiary butyl ether (MTBE), methanol, ethyl tertiary butyl ether (ETBE) or ethanol are used to increase the oxygen content of motor fuel. Do these additives improve air quality The answer is a qualified no. Although oxygenated fuels reduce emissions from older automobiles, there is no statistical improvement in automotive emissions for newer vehicles equipped with three-way catalytic converters. Oxygenates have increased overall fuel cost $14 million annually in the Denver area but have not improved air quality as expected.
