The cetane number test uses a standard single cylinder variable compression ratio diesel engine. Cetane index is a calculated value, which is derived from relatively easily measured fuel properties. Thus, cetane index can provide a measure of fuel ignition quality without the need to run the costly cetane number test.

Most diesels for standard vehicles and general highway usage normally require a cetane rating that falls between 45 to around 55. The table below outlines the different grades of cetane numbers that correspond with various diesel fuels that are compression ignited. A General Guide to Cetane Numbers and Diesel (DOC)

All the sundry hydrocarbon constituents of diesel fuel are measured and indexed against cetane's base-100 rating. The cetane index is a figure which denotes the quality of a diesel fuel, based upon its density and volatility, and which is roughly approximate to its cetane number. It is loosely linked to the octane number of gasoline, since both give a measure of each substance’s efficacy and are inversely related. Diesel is a product that is extensively used in daily life. Towards the end of the production process, multiple quality parameters need to be determined before it can be sold on the market. These parameters include Cetane Number (CN or CETN), Cetane Index (CI or CETI), sulfur content, flash point, density, Cold Filter Plugging Point (CFPP) or boiling points (T95). Most diesels for standard vehicles and general highway usage normally require a cetane rating that falls between 45 to around 55.

The correlations were found to be differ-ent for light and heavy diesel fuels.

These indexes are: diesel index, characterization factor, ignition quality number, modified ignition quality number and calculated cetane number. The calculated cetane number was adjudged the most satisfactory of the five indexes from the standpoint of accuracy, correlation and convenience of use.

Octane number measures the performance of gasoline while cetane number measure the performance of the diesel. The fuel having high octane number has the low cetane number and high cetane number fuel has low octane number. 2016-08-30 Cetane rating, also known as cetane number is a measurement of the quality or performance of diesel fuel. The higher the number, the better the fuel burns within the engine of a vehicle.

Higher cetane numbers mean shorter ignition delay and at the same time a better performance of the diesel engine: The injected fuel burns more evenly and
