1、Designation: D4814 16dD4814 16eStandard 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

2、number in 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 r

3、equirements of liquid automotive fuels for ground vehicles equipped withspark-ignition engines.1.2 This specification describes various characteristics of automotive fuels for use over a wide range of operating conditions.It provides for a variation of the volatility and water tolerance of automotiv

4、e fuel in accordance with seasonal climatic changesat the locality where the fuel is used. For the period May 1 through Sept. 15, the maximum vapor pressure limits issued by theUnited States (U.S.) Environmental Protection Agency (EPA) are specified for each geographical area except Alaska and Hawai

5、i.Variation of the antiknock index with seasonal climatic changes and altitude is discussed in Appendix X1.This specification neithernecessarily includes all types of fuels that are satisfactory for automotive vehicles, nor necessarily excludes fuels that can performunsatisfactorily under certain op

6、erating conditions or in certain equipment. The significance of each of the properties of thisspecification is shown in Appendix X1.1.3 The spark-ignition engine fuels covered in this specification are gasoline and its blends with oxygenates, such as alcoholsand ethers and where gasoline is the prim

7、ary component by volume in the blend. The concentrations and types of oxygenates arenot specifically limited in this specification. The composition of both unleaded and leaded fuel is limited by economic, legal, andtechnical consideration, but their properties, including volatility, are defined by t

8、his specification. In many countries, regulatoryauthorities having jurisdiction have set laws and regulations that limit the concentration of oxygenates and certain other compoundsfound in spark-ignition engine fuel. In the United States, oxygenate types and concentrations are limited to those appro

9、ved underthe U.S. Environmental Protection Agencys (EPA) substantially similar 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 specificationcan be more or less restrictive

10、 than the EPA rules, regulations, and waivers. Refer to Appendix X3 for discussions of EPA rulesrelating to fuel volatility, lead and phosphorous contents, sulfur content, benzene content, deposit control additive certification, anduse of oxygenates in blends with unleaded gasoline. Contact the EPA

11、for the latest versions of the rules and additionalrequirements.1.4 This specification does not address the emission characteristics of reformulated spark-ignition engine fuel. Reformulatedspark-ignition engine fuel is required in some areas to lower emissions from automotive vehicles, and its chara

12、cteristics aredescribed in the research report on reformulated spark-ignition engine fuel.2 However, in addition to the legal requirements foundin this research report, reformulated spark-ignition engine fuel should meet the performance requirements found in thisspecification.1.5 This specification

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

14、to the latest edition.NOTE 1If there is any doubt as to the latest edition of Specification D4814, contact ASTM International Headquarters.1.6 Tests applicable to gasoline are not necessarily applicable to its blends with oxygenates. Consequently, the type of fuel underconsideration must first be id

15、entified in order to select applicable tests. Test Method D4815 provides a procedure for determiningoxygenate concentration in mass percent.

Appendix X4 provides a procedure for calculating the mass oxygen content of a fuelusing measured oxygenate type, oxygenate concentration in volume percent, and measured density or relative density of the fuel.1.7 The following applies to all specified lim

21、its in this standard: For purposes of determining conformance with thesespecifications, an observed value or a calculated value shall be rounded “to the nearest unit” in the right-most significant digit usedin expressing the specification limit, in accordance with the rounding method of Practice E29

22、. For a specification limit expressedas an integer, a trailing zero is significant only if the decimal point is specified. For a specified limit expressed as an integer, andthe right-most digit is non-zero, the right-most digit is significant without a decimal point being specified. This convention

23、appliesto specified limits in Tables 1, 3, and X8.1, and it will not be observed in the remainder of this specification.1.8 The values stated in SI units are the standard, except when other units are specified by U.S. federal regulation. Values givenin parentheses are provided for information only.N

24、OTE 2Many of the values shown in Table 1 were originally developed using U.S. customary units and were subsequently soft-converted to SI values.As a result, conversion of the SI values will sometimes differ slightly from the U.S. customary values shown because of round-off. In some cases, U.S.federa
