EPA issues emergency fuel waiver for E15 sales

Green Car Congress

MAY 2, 2022

The US Environmental Protection Agency (EPA) is issuing an emergency fuel waiver to allow E15 gasoline to be sold during the summer driving season. The Clean Air Act (CAA) requires the use of low-volatility gasoline during the summer months in order to limit the formation of ozone pollution. Earlier post.). EPA provides a 1.0

A study by a team of researchers from France and the US found that the origin of volatile hydrocarbons, other than methane, present in city air is mainly gasoline-powered vehicles. They therefore concluded that gasoline engines are probably the main source of volatile hydrocarbons in both cities.

The results, published in an open-access paper in the journal Science , suggest that the focus of efforts to mitigate ozone formation and toxic chemical burdens need to be adjusted, the authors suggested. Gasoline is stored in closed, hopefully airtight, containers and the VOCs in gasoline are burned for energy. McDonald et al.

After ten years in orbit, the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite has been in orbit sufficiently long to show that people in major US cities are breathing less nitrogen dioxide. The gas is produced primarily during the combustion of gasoline in vehicle engines and coal in power plants.

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

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.

Vehicles that are engine certified include incomplete gasoline vehicles and those powered with diesel engines.
