 Cetane machine in accordance with ASTM D613, GB/T386 or standards fixed ignition lag measured cetane number of diesel and biodiesel, this product is suitable for nature of sample with a known ignition diesel cetane standard fuel (cetane and heptamethy l nonane mixture at a volume ratio) comparing ignition properties determined. specific method is to change compression ratio of engine Graduated flask, in order to obtain determined ignition lag (delay) period, fuel injection start and combustion (combustion) time interval between start. When sample or standard fuel in combustion process, this time interval should be fixed at 20 ° (crank angle of generator meter), but different fuel required for combustion of different compression ratio, which is end of compression stroke, temperature and pressure are different. Compression ratio according to sample gas is not more than five scale readings select two standard fuel cetane units, obtained in same way to determine ignition lag. When sample gas compression ratio scale reading in one of two standard fuel gas between scale readings, sample is calculated is designed and made as per interpolation of cetane number, symbol × ×.× / CN. For example 45.6/CN.
