“cetane number”的概念、定义、翻译、参考文献-科学参考

cetane number

Physics

A number that provides a measure of the ignition characteristics of a Diesel fuel when it is burnt in a standard Diesel engine. It is the percentage of cetane (hexadecane) in a mixture of cetane and 1-methylnaphthalene that has the same ignition characteristics as the fuel being tested. Compare octane number.

Chemical Engineering

A number used as a measure of diesel fuels that represents the percentage of hexadecane (i.e. cetane) in a mixture with 1-methylnaphthalene that has the same ignition characteristics as a diesel fuel being tested in a standard diesel engine. It is therefore an indication of the ease of self-ignition. The cetane index is a number calculated from the average boiling point and the density of a petroleum fraction in the diesel fuel boiling range, which estimates the cetane number of the fraction.
