These test fuel blends are used to determine permeation and fuel compatibility of various materials used in automotive fuel systems. These fuels do not contain
3、the additive packages (detergents, antioxidants, lubricity modifiers, etc.) found in most commercial fuels. Their use in engineering testing protocols should take this into consideration.

7、ABORATORY TEST METHOD AZ 105-02 Copyright 2016, Ford Global Technologies, LLC Page 2 of 4 Oxygenate and Alternative Fuel Codes (Y) Several oxygenates (alcohols and ethers) are in use or have been identified as potential candidates for use in reformulated gasolines. The most common include: M = metha
8、nol E = ethanol ME= methyl tertiary butyl ether EE = ethyl tertiary butyl ether TE = tertiary amyl methyl ether Higher molecular weight alcohols (isopropyl and t-butyl) and ethers (diisopropyl and ethyl t-amyl) may find some usage. Alcohol based alternative fuels will consist of blends of ethanol (0
