ASTM D4814-2018 Standard Specification for Automotive Spark-Ignition Engine Fuel.pdf

1、Designation: D4814 18Standard Specification forAutomotive Spark-Ignition Engine Fuel1This standard is issued under the fixed designation D4814; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in

2、parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 This specification covers the establishment of require-men

3、ts of liquid automotive fuels for ground vehicles equippedwith spark-ignition engines.1.2 This specification describes various characteristics ofautomotive fuels for use over a wide range of operatingconditions. It provides for a variation of the volatility and watertolerance of automotive fuel in a

4、ccordance with seasonalclimatic changes at the locality where the fuel is used. For theperiod May 1 through Sept. 15, the maximum vapor pressurelimits issued by the United States (U.S.) Environmental Pro-tection Agency (EPA) are specified for each geographical areaexcept Alaska and Hawaii. Variation

5、 of the antiknock indexwith seasonal climatic changes and altitude is discussed inAppendix X1. This specification neither necessarily includesall types of fuels that are satisfactory for automotive vehicles,nor necessarily excludes fuels that can perform unsatisfactorilyunder certain operating condi

6、tions or in certain equipment. Thesignificance of each of the properties of this specification isshown in Appendix X1.1.3 The spark-ignition engine fuels covered in this specifi-cation are gasoline and its blends with oxygenates, such asalcohols and ethers and where gasoline is the primary compo-nen

7、t by volume in the blend. The concentrations and types ofoxygenates are not specifically limited in this specification.The composition of both unleaded and leaded fuel is limited byeconomic, legal, and technical consideration, but theirproperties, including volatility, are defined by this specifica-

8、tion. In many countries, regulatory authorities having jurisdic-tion have set laws and regulations that limit the concentrationof oxygenates and certain other compounds found in spark-ignition engine fuel. In the United States, oxygenate types andconcentrations are limited to those approved under th

9、e U.S.Environmental Protection Agencys (EPA) substantially simi-lar rule (see X3.3.1), waivers, and partial waivers includingsome restrictions on vehicle and equipment use (see X3.3.2).With regard to fuel properties, including volatility, this speci-fication can be more or less restrictive than the

10、EPA rules,regulations, and waivers. Refer to Appendix X3 for discussionsof EPA rules relating to fuel volatility, lead and phosphorouscontents, sulfur content, benzene content, deposit controladditive certification, and use of oxygenates in blends withunleaded gasoline. Contact the EPA for the lates

11、t versions ofthe rules and additional requirements.1.4 This specification does not address the emission char-acteristics of reformulated spark-ignition engine fuel. Refor-mulated spark-ignition engine fuel is required in some areas tolower emissions from automotive vehicles, and its character-istics

12、 are described in the research report on reformulatedspark-ignition engine fuel.2However, in addition to the legalrequirements found in this research report, reformulated spark-ignition engine fuel should meet the performance requirementsfound in this specification.1.5 This specification represents

13、a description of automotivefuel as of the date of publication. The specification is undercontinuous review, which can result in revisions based onchanges in fuel, automotive requirements, or test methods, or acombination thereof. All users of this specification, therefore,should refer to the latest

14、edition.NOTE 1If there is any doubt as to the latest edition of SpecificationD4814, contact ASTM International Headquarters.1.6 Tests applicable to gasoline are not necessarily appli-cable to its blends with oxygenates. Consequently, the type offuel under consideration must first be identified in or

15、der toselect applicable tests. Test Method D4815 provides a proce-dure for determining oxygenate concentration in mass percent.Test Method D4815 also includes procedures for calculatingmass oxygen content and oxygenate concentration in volumepercent. Appendix X4 provides a procedure for calculating

16、themass oxygen content of a fuel using measured oxygenate type,oxygenate concentration in volume percent, and measureddensity or relative density of the fuel.1This specification is under the jurisdiction of ASTM Committee D02 onPetroleum Products, Liquid Fuels, and Lubricants and is the direct respo

21、ecification limit, in accordance withthe rounding method of Practice E29. For a specification limitexpressed as an integer, a trailing zero is significant only if thedecimal point is specified. For a specified limit expressed as aninteger, and the right-most digit is non-zero, the right-mostdigit is

22、 significant without a decimal point being specified. Thisconvention applies to specified limits in Tables 1, 3, and X8.1,and it will not be observed in the remainder of this specifica-tion.1.8 The values stated in SI units are the standard, exceptwhen other units are specified by U.S. federal regul

23、ation.Values given in parentheses are provided for information only.NOTE 2Many of the values shown in Table 1 were originallydeveloped using U.S. customary units and were subsequently soft-converted to SI values. As a result, conversion of the SI values willsometimes differ slightly from the U.S. cu

In some cases, U.S. federal regulations specify non-SI units.1.9 This standard does not purport to address all of thesafety concerns, if any, associated with its use.
