CRC Octane Number Requirement Rating Workshop 1992
Abstract
An octane number requirement rating workshop was conducted. The objective of the workshop was to improve the application of the CRC E-15 Technique for Determination of Octane Number Requirement of Light-Duty Vehicles. The workshop was to improve the skills of those with minimal experience and provide experienced raters a forum for interacting with other raters of similar experience. Investigative procedures and techniques were encouraged to provide data regarding the latest electronic engine controls such as knock sensors and adaptive learning strategies. Eleven 1991 and 1992 model year vehicles were used for track practice and testing. Five of the vehicles were equipped with auxiliary fuel systems to allow operation on the octane number reference fuels. The other six vehicles were equipped with tachometers and vacuum gauges for determination of transmission shift characteristics. Several scan tools were available and were used on most of the GM vehicles to monitor knock sensor activity and spark timing. The test fuels used were full-boiling range unleaded fuels.
