ASTM D4814-2014a Standard Specification for Automotive Spark-Ignition Engine Fuel《汽车火花点火发动机燃料的标准规格》.pdf

1、Designation: D4814 14D4814 14aStandard 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 n

2、umber 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 re

3、quirements of 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 automotive fuel i

4、n 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 Hawaii.Variat

5、ion 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 operating

6、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. This specification does not apply to

7、fuels that contain an oxygenate as the primary component, such as Fuel Methanol(M85). The concentrations and types of oxygenates are not specifically limited in this specification. However, depending onoxygenate type, as oxygenate content increases above some threshold level, the likelihood for vehi

8、cle problems also increases. Thecomposition of both unleaded and leaded fuel is limited by economic, legal, and technical consideration, but their properties,including volatility, are defined by this specification. In addition, the composition of unleaded fuel is subject to the rules,regulations, an

9、d Clean Air Act waivers of the U.S. Environmental Protection Agency (EPA). With regard to fuel properties,including volatility, this specification can be more or less restrictive than the EPA rules, regulations, and waivers. Refer toAppendix X3 for discussions of EPA rules relating to fuel volatilit

10、y, lead and phosphorous contents, deposit control additivecertification, and use of oxygenates in blends with unleaded gasoline. Contact the EPA for the latest versions of the rules andadditional requirements.1.4 This specification does not address the emission characteristics of reformulated spark-

11、ignition engine fuel. Reformulatedspark-ignition engine fuel is required in some areas to lower emissions from automotive vehicles, and its characteristics aredescribed in the research report on reformulated spark-ignition engine fuel.2 However, in addition to the legal requirements foundin this res

12、earch report, reformulated spark-ignition engine fuel should meet the performance requirements found in thisspecification.1.5 This specification represents a description of automotive fuel as of the date of publication. The specification is undercontinuous review, which can result in revisions based

13、 on changes in fuel, automotive requirements, or test methods, or acombination thereof. All users of this specification, therefore, should refer 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 applic

14、able to gasoline are not necessarily applicable to its blends with oxygenates. Consequently, the type of fuel underconsideration must first be identified in order to select applicable tests. Test Method D4815 provides a procedure for determiningoxygenate concentration in mass percent. Test Method D4

15、815 also includes procedures for calculating mass oxygen content andoxygenate concentration in volume 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

16、density of the fuel.1 This specification is under the jurisdiction ofASTM Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants and is the direct responsibility of SubcommitteeD02.A0.01 on Gasoline and Gasoline-Oxygenate Blends.Current edition approved May 1, 2014June 15, 2014.

Becauseit may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as approp

20、s11.7 The following applies to all specified limits 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 acc

21、ordance with the rounding method of Practice E29. 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

22、 decimal point being specified. This convention appliesto specified limits in Tables 1, 3, and Table X7.1, 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 g

23、ivenin parentheses are provided for information only.NOTE 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

24、 shown because of round-off. In some cases, U.S.federal regulations specify non-SI units.1.9 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety and health practice
