ASTM D613,FDR-3622 Cetane number tester

Deskripsyon:
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 ××. × / CN. For example, 45.6 / CN.
