This specification covers the performance requirements for a high octane number test fuel suitable for spark-ignition engines to be used in ground vehicles that will require 100 research octane number (RON) minimum rated fuel. The fuels described by this specification are intended for developing technologies that lead to reduced vehicle energy consumption, such as higher compression ratio, higher power density, increased turbocharger boost pressure, smaller swept displacement volume, and operation at lower engine speeds. These fuels may contain oxygenates, such as alcohols and ethers, up to 50% by volume, and both fossil and bio-derived components.
