• 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
As a quick reference, here are lambda values and their AFR equivalents for different fuels. This is handy to use when looking at a wideband display/gauge that displays a gas scale AFR or just for curiosity’s sake.
Printable Version. E85 Flex Fuel Specification. ASTM International developed a specification for gasoline-ethanol blends containing 51% to 83% ethanol to ensure proper vehicle starting, operation, and safety in varying temperature conditions.
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.
Compared with gasoline, E85 fuel reduces CO, NO x, benzene, toluene and 1,3-butadiene emissions, and also fuel evaporative emissions. In the opposite, acetaldehyde, ethanol, formaldehyde and methane emissions tend to be elevated for E85 when running with a cold engine.
