• 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.
The table below shows the requirements of the ASTM D5798 Standard Specification for Ethanol Fuel Blends for Flexible-Fuel Automotive Spark-Ignition Engines. ASTM regularly updates standards, and the latest version of the specification is available on the ASTM International website.
13 lut 2024 · At Shiftech, you have several options for converting your vehicle to run on E85 bioethanol: The E85 Flex-fuel conversion, from €590 incl. VAT, allows your vehicle to run on ethanol, petrol or a mixture of the two, without any increase in power.
E85 is a nominal blend of 85 percent ethanol and 15 percent gasoline that is an alternative fuel for automobiles. The actual ethanol content of E85 can vary depending upon the month of the year and geographical location, and may be as little as 70 percent ethanol.
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.
