1、Designation: D 4814 09bStandard Specification forAutomotive Spark-Ignition Engine Fuel1This standard is issued under the fixed designation D 4814; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number
2、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 Department of Defense.1. Scope*1.1 This specification covers the establishment of require-ments
3、 of automotive fuels for ground vehicles equipped withspark-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 accordance
4、 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 U.S. Environmental Protection Agency(EPA) are specified for each geographical area except Alaskaand Hawaii. Variation of the antiknock index wit
5、h seasonalclimatic changes and altitude is discussed in Appendix X1.This specification neither necessarily includes all types of fuelsthat are satisfactory for automotive vehicles, nor necessarilyexcludes fuels that can perform unsatisfactorily under certainoperating conditions or in certain equipme
6、nt. The significanceof each of the properties of this specification is shown inAppendix X1.1.3 The spark-ignition engine fuels covered in this specifi-cation are gasoline and its blends with oxygenates, such asalcohols and ethers. This specification does not apply to fuelsthat contain an oxygenate a
7、s the primary component, such asFuel Methanol (M85). The concentrations and types of oxy-genates are not specifically limited in this specification. How-ever, depending on oxygenate type, as oxygenate contentincreases above some threshold level, the likelihood for vehicleproblems also increases. The
8、 composition of both unleaded andleaded fuel is limited by economic, legal, and technicalconsideration, but their properties, including volatility, aredefined by this specification. In addition, the composition ofunleaded fuel is subject to the rules, regulations, and Clean AirAct waivers of the U.S
9、. Environmental Protection Agency(EPA). With regard to fuel properties, including volatility, thisspecification can be more or less restrictive than the EPA rules,regulations, and waivers. Refer toAppendix X3 for discussionsof EPA rules relating to fuel volatility, lead and phosphorouscontents, depo
10、sit control additive certification, and use ofoxygenates in blends with unleaded gasoline. Contact the EPAfor the latest versions of the rules and additional requirements.1.4 This specification does not address the emission char-acteristics of reformulated spark-ignition engine fuel. Refor-mulated s
11、park-ignition engine fuel is required in some areas tolower emissions from automotive vehicles, and its character-istics are described in the research report on reformulatedspark-ignition engine fuel.2However, in addition to the legalrequirements found in this research report, reformulated spark-ign
12、ition engine fuel should meet the performance requirementsfound in this specification.1.5 This specification represents 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 requir
13、ements, 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 SpecificationD 4814, contact ASTM International Headquarters.1.6 Tests applicable to gasoline are not necessarily ap
14、pli-cable to its blends with oxygenates. Consequently, the type offuel under consideration must first be identified in order toselect applicable tests. Test Method D 4815 provides a proce-dure for determining oxygenate concentration in mass percent.Test Method D 4815 also includes procedures for cal
15、culatingmass oxygen content and oxygenate concentration in volumepercent. Appendix X4 provides a procedure for calculating themass oxygen content of a fuel using measured oxygenate type,oxygenate concentration in volume percent, and measureddensity or relative density of the fuel.1.7 The following a

For a specified limit expressed as aninteger, and the right-most digit is non-zero, the right

Thisconvention applies to specified limits in Tables 1, 3, and TableX8.1, and it will not be observed in the remainder of thisspecification.1.8 The values stated in SI units are the standard, exceptwhen other units are specified by f
21、ederal regulation. Valuesgiven 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
22、 the U.S. customary values shown becauseof round-off. In some cases, federal regulations specify non-SI units.1.9 The following safety hazard caveat pertains only to thetest method portion, Annex A1, of this specification.
