cetaneindex
Cetane Index is an empirical estimate of the cetane number (CN) of diesel fuels. The CN is a measure of ignition quality in compression-ignition engines, but direct CN determination requires specialized equipment and procedures. The Cetane Index provides a practical alternative by estimating CN from simpler, routinely measured fuel properties. It is commonly used in quality control, fuel specification, and process optimization to compare ignition quality when direct CN testing is unavailable or impractical.
Calculation of the Cetane Index relies on correlations between CN and standard fuel properties. The most common
Interpretation and use: A higher Cetane Index indicates a fuel estimated to have better ignition quality, but
