Diesel index and cetane number

In general, alkanes have high, aromatics low, and naphthenes intermediate, cetane and diesel indices. The current standard for diesel sold in European Union, Iceland, Norway and Switzerland is set in EN 590, with a minimum cetane index of 46 and a minimum cetane number of 51. Premium diesel fuel can have a cetane number as high as 60. Diesel engine operation is primarily related to the actual cetane number, and the cetane index is simply an estimation of the base (unadditized) cetane number. Cetane number should equal or exceed cetane index, depending on the amount of additive used. The most common additive is 2-ethylhexyl nitrate (2EHN).

Cetane Index 3.2 Test Method D4737 may also be used to approximate the ASTM cetane number of diesel fuels.

The cetane number is the most significant property of diesel fuels affecting engine performance and emissions. Cetane number varies with hydrocarbon types present in diesel fuels. Normal paraffins have high cetane numbers that increase with carbon number. Isoparaffins have a wide range of cetane numbers, from about 10 to 80.

Cetane number - Wikipedia Cetane index is used as a substitute for the cetane number of diesel fuel. Cetane index - Wikipedia The fuel contains no sulfur or aromatics, and has a high cetane number. Because the ASTM D-613 test is time consuming and expensive, calculated cetane index is derived from the fuel's density and boiling range. While useful for estimating the cetane number of distilled fuels, this technique can not be applied to fuels containing conditioners that raise cetane number. Cetane Index is calculated from ASTM D 86 distillation and density and correlates with CN of diesel not containing cetane improver. Please see ASTM D 4737 Sections 1 and 4. If cetane improver is added, Cetane Number will increase, but ASTM D 86 distillation and density results will not change.

Number may be increased through the refining process or the blending of combustion ignition- improving additives by fuel suppliers. Cetane Index 3.2 Test Method D4737 may also be used to approximate the ASTM cetane number of diesel fuels. 3.2.1 Procedure A of Test Method D4737 was developed as a Feb 1, 2020 Abstract. Water-in-diesel emulsion, also known as WIDE fuel, is one of the promising alternative fuels for diesel engines due to its positive Jan 5, 2009 Cetane index is a correlation that predicts cetane number of diesel that does not contain cetane-improving additives. According to ASTM D-4737, Cetane testing requires testing for the Cetane Number, Derived Cetane Number and Calculated Cetane Index. These tests measure diesel and fuel oil number of 100, while alpha-methyl naphthalene was assigned a cetane number of 0.

The cetane number, cetane index, and derived cetane number (IQT) tests measure the ignition quality of diesel, gasoil, biodiesel, heating gasoil and number-two fuel oil fuels. Cetane tests measure diesel and fuel oil characteristics related to fuel quality.
