Definition of cetane number in English English dictionary
A performance rating of diesel fuel corresponding to the percentage of cetane in a mixture with methylnaphthalene that would have the same performance
A measure of how well a diesel fuel will ignite, and how much white smoke and knock will be produced
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 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 ignition quality of diesel fuel The higher the cetane number, the easier the fuel ignites when it is injected into the engine
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
A number indicating the relative ignitability of a fuel oil for compression-ignition engines
