The performance rating of a diesel fuel, corresponding to the percentage of cetane in a cetane-methylnaphthalene mixture with the same ignition performance. A higher cetane number indicates greater fuel efficiency. Also called cetane rating
A number which expresses the ignition quality of a diesel fuel and equal to the percentage of volume by cetane (C16H34) in a blend with methyl naphthalene, which blend has the same ignition performance as the test fuel
A measure of the ignitability of diesel fuel Diesel fuel generally has to meet a cetane number specification of 40 As a measure of performance, the cetane number serves a similar purpose as does the octane number of gasoline
The cetane number of distillate fuels as estimated from the API gravity and mid-boiling point by using a formula given in Appendix II of ASTM Method D 975 This estimate is used if a standard test engine is not available, or if the sample is too small for an engine test
(Otomotiv) Similar to octane in gasoline, this is a diesel oil rating based on the time lapse between fuel injection and ignition to determine how easily the oil ignites and how fast it burns. See also octane rating
