3、report reference editorially in November 2011.1. Scope*1.1 This laboratory test method covers the quantitative determination of the knock rating of liquid spark-ignition engine fuelin terms of Research O.N., except that this test method may not be applicable to fuel and fuel components that are prim
4、arilyoxygenates.2The sample fuel is tested using a standardized single cylinder, four-stroke cycle, variable compression ratio,carbureted, CFR engine run in accordance with a defined set of operating conditions. The O.N. scale is defined by the volumetriccomposition of PRF blends. The sample fuel kn
5、ock intensity is compared to that of one or more PRF blends. The O.N. of the PRFblend that matches the K.I. of the sample fuel establishes the Research O.N.1.2 The O.N. scale covers the range from 0 to 120 octane number but this test method has a working range from 40 to 120Research O.N. Typical com
6、mercial fuels produced for spark-ignition engines rate in the 88 to 101 Research O.N. range. Testingof gasoline blend stocks or other process stream materials can produce ratings at various levels throughout the Research O.N.range.1.3 The values of operating conditions are stated in SI units and are
7、 considered standard. The values in parentheses are thehistorical inch-pound units. The standardized CFR engine measurements continue to be in inch-pound units only because of theextensive and expensive tooling that has been created for this equipment.1.41.4 WARNINGMercury has been designated by man
