What is BS EN 16906 - Determination of the ignition quality of diesel fuels - BASF engine method about?
BS EN 16906 specifies a test method for the determination of cetane numbers (“ CN ”) in diesel fuel in the range from CN 45 to CN 63, using a standard single cylinder, four-stroke cycle, indirect injection engine.
BS EN 16906 is applicable to distillate as well as paraffinic diesel fuels intended for use in diesel engines, including those containing fatty-acid methyl esters (FAME), ignition-improvers or other additives. The cetane number scale comprises a range from zero to 100, but typical testing is currently performed in the range from about 40 CN to about 75 CN .
Note 1: This engine test procedure may be used for other fuels such as synthetics and vegetable oils. However, samples with fuel properties that interfere with the gravity-based pre-supply pressure to the fuel pump e.g. due to high viscos...
