diesel engine in accordance with ASTM D613, GB / T386 and other standards with
fixed ignition lag determination cetane number of diesel and biodiesel, this
product is suitable for the ignition quality of diesel fuel sample with a known
cetane number The standard fuel (cetane and heptamethyl nonane certain volume
mixture) comparing the ignition properties determined. The specific method is
to change the compression ratio of the engine cylinder, in order to obtain the
determined ignition lag (delay) period, that the fuel injection start and
combustion (combustion) time interval between the start. Whether the sample or
the standard fuel in the combustion process, this time interval should be fixed
at 20 degrees (the generator crank angle count), but with different fuels at
different compression ratios required for combustion, that is, the end of the
compression stroke, temperature and pressure differences. According to the
compression ratio of the sample gas gauge reading select no more than two
standard fuel cetane number five units, obtained in the same manner to
determine the ignition lag. When the sample is compressed between the gas gauge
reading in more than two standard fuel gas gauge reading, the cetane number is
calculated by interpolation of the sample, the symbol Ã—Ã—. Ã— / CN. For example,
45.6 / CN.
