A cetane number is a relative ranking of fuels based on the amount of time between fuel injection and ignition (ignition delay) in a diesel engine. A minimum cetane number is specified in the ASTM standard that defines the quality of diesel fuel sold in the United States. The recently published Compendium of Experimental Cetane Numberscompiles cetane number data from 62 sources for readers to use in selecting potential compounds and formulas for development of models, tools, and fuels.
In addition to updating information, the new edition provides additional measurements on a larger number of compounds, along with assessment of data quality.
The updated report includes all available single-compound cetane number data found in the scientific literature published prior to March 2014, including:
Information on 389 pure compounds
584 measurements, including more than 250 new measurements
Expanded discussion of the accuracy and precision of the methods most commonly used for determining cetane numbers
Extensive annotation allowing readers to judge the relative reliability of individual results.
