There are widespread policy assumptions that the phase-out of gasoline and diesel internal combustion engines will over time lead to much reduced emissions of Volatile Organic Compounds (VOCs) from road transport and related fuels. Cliff et al. While some VOCs are released in exhaust, others may arise from an unexpected source—e.g.,

Higher octane fuels can lead to higher compression ratios which in turn can lead to more efficient gasoline engines and reduced fuel consumption. With turbocharged gasoline engines, there is a double benefit: higher compression ratios and increased boost. Currently, the Clean Air Act limits the volatility of gasoline to 9.0

This would increase market access opportunities for higher blends of ethanol by allowing retailers across the country to sell E15 and other higher-ethanol/gasoline fuel blends year-round, the Senators said.

Power management company Eaton has introduced a complete suite of solutions from its Vehicle Group to reduce vapor emissions produced during the refueling of gasoline-powered vehicles. This leakage occurs in all gasoline-powered vehicles, including passenger cars and an increasing number of small- and mid-sized commercial vehicles.

They found that levels of pollutants that can contribute to the formation of ground-level ozone, or smog, have failed to continue a fairly steady decline as estimated by the US Environmental Protection Agency. These results show that meeting future air quality standards for ozone pollution will be more challenging than previously thought.

In 1975, General Ernesto Geisel, then-president of Brazil, ordered the country’s gasoline supply mixed with 10% ethanol. The level was raised to 25% over the next five years, which was intended to maintain a constant Brazilian gasoline supply for an ever-increasing demand. These were arguably the first flex-fuel vehicles.

Isoprene, a five-carbon diene formed naturally in plants and animals and a precursor of ozone, contributes more than 40% of these emissions. There is much more isoprene emitted to the atmosphere than all of the gases (gasoline, industrial chemicals) emitted by human activities, with the important exceptions of methane and carbon dioxide.
