标准范围
This International Standard establishes the rating of liquid spark-ignition engine fuel in terms ofan arbitrary scale of octane numbers using a standard single-cylinder, four-stroke cycle, variablecompressionratio, carburetted, CFR engine operated at constant speed. Motor octane number (MON)provides a measure of the knock characteristics of motor fuels in automotive engines under severeconditions of operation. The motor octane number provides a measure of the knock characteristics ofaviation fuels in aviation piston engines, by using an equation to correlate to aviation-method octanenumber or performance number (lean-mixture aviation rating).This International Standard is applicable for the entire scale range from 0 MON to 120 MON, but theworking range is 40 MON to 120 MON. Typical motor fuel testing is in the range of 80 MON to 90 MON.Typical aviation fuel testing is in the range of 98 MON to 102 MON.This International Standard is applicable for oxygenate-containing fuels containing up to 4,0 % (m/m)oxygen and for gasoline containing up to 25 % (V/V) ethanol.
