This European Standard specifies a test method for the quantitative determination of ignition delay of middle distillate fuels intended for use in compression ignition engines. The method utilizes a constant volume combustion chamber designed for operation by compression ignition, and employing direct injection of fuel into compressed air that is controlled to a specified pressure and temperature. An equation is given to calculate the derived cetane number (DCN) from the ignition delay measurement.<\/p>\n

This European Standard is applicable to diesel fuels, including those containing fatty acid methyl esters (FAME) up to 30 % ( V\/V<\/i>). The method is also applicable to middle distillate fuels of non-petroleum origin, oil-sands based fuels, blends of fuel containing biodiesel material, diesel fuel oils containing cetane number improver additives and low-sulfur diesel fuel oils. However, users applying this standard especially to unconventional distillate fuels are warned that the relationship between derived cetane number and combustion behaviour in real engines is not yet fully understood.<\/p>\n

The test method is also applicable to the quantitative determination of the ignition characteristics of FAME, especially the ignition delay. However the correlation data available were inconclusive about the precision of the equation. So the determination of derived cetane number for FAME fuel, also known as B100, has not been included in the precision determination as in Clause 12<\/span> 2)<\/sup> <\/span>.<\/p>\n

This European Standard covers the ignition delay range from 2,8 ms to 6,3 ms (71 DCN to 34 DCN). The combustion analyser can measure shorter or longer ignition delays, but precision is not known. For these shorter or longer ignition delays the correlation equation for DCN is given in Annex D<\/span>.<\/p>\n

\n
\n NOTE 1\n <\/div>\n

There is no information about how DCNs outside the 34 to 71 range compares to EN ISO 5165<\/span> <\/span>.<\/p>\n<\/div>\n

\n
\n NOTE 2\n <\/div>\n

For the purpose of this European Standard, the expression \u201c % ( V\/V<\/i>)\u201d is used to represent the volume fraction and \u201c% ( m\/m<\/i>)\u201d the mass fraction.<\/p>\n<\/div>\n

The use of this standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/b><\/p>\n<\/div>\n
