• E85 is a fuel blend containing up to 85% renewable ethanol by volume, completed by a petrol base1. Renewable ethanol is made from biomass feedstock such as sustainably grown crops, wastes and residues. • E85 is already widely distributed in France and Sweden and is available, to a lesser extent, in other European
E85 has the highest oxygen content of any fuel available, making it burn even more cleanly and even more completely than any other fuel. E85 has 80% fewer gum-forming compounds than gasoline. Ethanol is rapidly biodegraded in surface water, groundwater and soil, and is the safest component in gasoline today.
The ASTM specifica-tion for E85 (flex fuel) is ASTM D5798 “Specification for Ethanol Fuel Blends for Flexible-Fuel for Automo-tive Spark Ignition Engines” (Table 3). The ethanol content of E85 is seasonally adjusted to improve vehicle cold-start and warm-up performance.
To use E85, a high-level blend containing 51%–83% ethanol (depending on geog-raphy and season), a vehicle must be a flexible fuel vehicle (FFV). Intermediate blends between E15 and E85 are also approved for FFVs.
E85 is an abbreviation typically referring to an ethanol fuel blend of 85% ethanol fuel and 15% gasoline or other hydrocarbon by volume. In the United States, the exact ratio of fuel ethanol to hydrocarbon may vary according to ASTM 5798 that specifies the allowable ethanol content in E85 as ranging from 51% to 83%. [1]
How is Ethanol Made? Uncover the secrets behind E85 fuel and explore the intricate process of ethanol production. Delve into the eco-friendly aspects and learn about the sustainable future of ethanol as a fuel alternative.
High-oxygen-containing fuels, can be used in special flexible-fuel vehicles (FFV). Fuel containing ethanol up to 85% (E85) is used, for example, in Brazil, North America and in many European countries. In Brazil, FFVs are also designed for the use of hydrous E100 fuel.
