1980 CRC Octane Number Requirement Survey.

Abstract

In the 24th annual statistical survey of current model vehicles, test data were obtained on 429 1980 model vehicles, including 6 select models of special interest. Maximum octane number requirements under full- and part-throttle operating conditions were determined, and surface ignition knock 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 year's survey includes analyses for the following vehicle categories: (1) U.S. and Imported Vehicles--429 vehicles; (2) U.S. and Imported Cars--407 cars; (3) U.S. Vehicles--334 vehicles; (4) U.S. Cars--326 cars; and (5) Imported Vehicles--85 vehicles. It should be noted that the term 'cars' designates passenger cars only, while ther term 'vehicles' includes passenger cars plus vans and light-duty trucks. The order of testing reference fuels was the same as the 1979 Survey, which is as follows: Tank Fuel, High Sensitivity Full-Boiling Range Unleaded (FBRSU) Fuels, Average Sensitivity Full-Boiling Range Unleaded (FBRU) Fuels, and Primary Reference (PR) Fuels.
