About the Course

This course is based on ASTM D2700 Standard Test Method for Motor Octane Number of Spark-Ignition Engine Fuel. This test method covers the quantitative determination of the knock rating of liquid spark-ignition engine fuel in terms of motor octane number, including fuels that contain up to 25 % v/v of ethanol.

The course takes approximately 1 hour to complete and includes instructional video content, interactive knowledge checks, and a self-grading quiz. Downloadable resources include a pdf of the standard.

Learning Outcomes

By the end of this course, you should be able to:

  • Identify apparatus, reagents, and reference materials used for determination of motor octane number of spark-ignition engine fuel, including components of the test engine and reagents used for the cylinder jacket coolant.
  • Recognize sampling requirements outlined for ASTM D2700.
  • Describe basic engine and instrument settings and standard operating conditions, including those for valve set-up and timing.
  • Recognize test variable characteristics, including barometric pressure compensation of cylinder height.
  • Describe procedures for engine standardization and checking engine performance, including determination of whether an engine is fit for use and methods of validating the engine system.
  • Recall the steps for bracketing and C.R. procedures for determining motor octane number, including steps to be taken when a fuel's O.N. falls outside of permissible tolerances.
  • Recognize steps for calculating the octane number.
  • Identify reporting requirements for ASTM D2700.
