(Specification)Standard Specification for Gasoline-like Test Fuel for Compression-Ignition Engines
Standard Specification for Gasoline-like Test Fuel for Compression-Ignition Engines
SCOPE
1.1 This specification covers the requirements of test fuels suitable for use in certain gasoline compression-ignition engines and vehicles, which have been specifically designed to operate on the fuel described in this specification. These gasoline-like fuels, which may contain certain gasoline blending components, are henceforth referred to in this specification as “gasoline compression-ignition (GCI) test fuels.”
1.1.1 The GCI test fuels described by this specification are only intended for use by engine and vehicle manufacturers in the continuing development of appropriately designed compression-ignition engines that can take advantage of certain chemical and physical properties of GCI test fuels to achieve higher efficiency and lower emissions (henceforth referred to as “GCI engines”). These GCI test fuels are not intended for use by the general public.
1.1.2 GCI engines include only those engines that directly inject fuel into the combustion chamber, and rely on autoignition of the fuel to initiate combustion part or all the time. Although various combustion strategies may be used depending on the fuel and engine operating condition, the level of fuel stratification is typically decreased in GCI engines under certain operating conditions relative to traditional diesel compression-ignition engines. Engines that use an auxiliary ignition source (such as a spark plug) some but not all of the time could qualify as GCI engines.
1.1.3 The GCI test fuels covered in this specification may contain oxygenates, such as alcohols and ethers. Recommended limits on the type and concentration of specific oxygenates are provided in Appendix X3.
1.2 This specification provides a description of GCI test fuels for automotive engines that are not currently widely available to the general public, but are being developed and require defined standard test fuels. Commercial fuels meeting the same or similar requirements as the GCI test fuels described in this specification could become available to the general public if/when such engines are introduced into commerce; however use of this specification by the general public would require significant modifications. The specification is under continuous review, which can result in revisions based on changes in fuel, automotive requirements, test methods, or a combination thereof. All users of this specification, therefore, should refer to the latest edition.
1.3 Traditional diesel compression-ignition engines and fuel systems are designed for use with fuel, which has a lower volatility, higher flash-point, and higher viscosity than GCI test fuels. Such engines are therefore usually unsuitable for use with GCI test fuels. Certain hardware modifications may be required for the safe use of low flash-point, GCI test fuels.
Note 1: If there is any doubt as to the latest edition of Specification D8275, contact ASTM International Headquarters.
1.4 The values stated in SI units are to be regarded as the standard. Any other values given are provided for information only.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
