Cetane scale: Function, problems and possible solutions
Conference
·
OSTI ID:6436526
This paper identifies the original function of the Cetane Scale and examines some problem of concern to the technical community. The following six problems have been analyzed: i) inability of the ASTM D-613 method to rate low ignition quality fuels, ii) instability of the ignition delay meter, iii) inconformity of the CFR combustion system with actual diesel systems, iv) invalidity of Cetane number in correlating the I.D. for different fuels, engines and operating conditions, v) inaccuracy of Cetane number in ranking the overall performance and emission behaviour of fuels in diesel engines and vi) inability of Cetane number in rating the cold startability of diesel engines on different fuels. Possible solutions to the above problems are examined.
