1981 CRC Octane Number Requirement Survey.

Abstract

In the 35th annual statistical survey of current model vehicles conducted by the Coordinating Research Council, Inc., test data were obtained on 429 1981 model vehicles, including nine select models of special interest. Maximum octane number requirements at either full- or part-throttle operating conditions were determined. Included also are the octane number requirements as determined by the new 50th percentile acceleration technique designed to more nearly represent customer-type driving. Surface ignition and rumble, if present, were also reported. Passenger cars and light-duty trucks including non-commercial vans (1/2-3/4 ton without four-wheel drive) were tested according to a weighted distribution. This years's Survey includes analyses of validated data for the following vehicle categories: US and Imported Vehicles -- 417 vehicles; US and Imported Cars -- 392 cars; US Vehicles -- 318 vehicles; US Cars--300 cars, and Imported Vehicles--99 vehicles.
