Calculated carbon aromaticity index
Web• Calculated Carbon Aromaticity Index (CCAI) – High CCAI fuels may have poor ignition and combustion qualities. Medium and high speed diesel engines and older diesels may be particularly affected at low or partial load. • Micro carbon residue – High levels can cause carbon deposits to form on fuel injectors.

WebCalculated Carbon Aromaticity Index (CCAI). This gives a number in the range of 800-870. Calculated Ignition Index (CII). This gives values in the same order as the cetane index for distillate fuels. Values less than 30 … Web8 The calculated carbon aromaticity index (CCAI) was developed many years ago as part of ISO 8217 for marine residual fuels. CCAI used to be a good indicator for ignition quality, which also depends on the aromatic content. The CCAI calculation methodology was based on refinery fuel oil parameter analysis, which was common in the 1980s.

The calculated carbon aromaticity index (CCAI) is an index of the ignition quality of residual fuel oil. The running of all internal combustion engines is dependent on the ignition quality of the fuel. For spark-ignition engines the fuel has an octane rating. For diesel engines it depends on the type of fuel, for distillate … See more Formula for CCAI: $${\displaystyle CCAI=D-140.7\log(\log(V+0.85))-80.6-210\ln \left({\frac {t+273}{323}}\right)}$$ which is equivalent to: See more This will normally give a value somewhere between 800 and 880. The lower the value is the better the ignition quality. Fuels with a CCAI higher than 880 are often problematic or even unusable in a diesel engine.
