The Cetane Number of diesel fuel is a measure of its ‘ignition quality’. High Cetane Number diesel fuels offer a variety of important engine performance and environmental benefits. Globally fuel specifications are being set with higher cetane number targets. It substantially helps to improve ignition quality, fuel economy, reduces noise and emissions, and allows for faster ignition at low temperatures and warm up with less misfiring.

Cetane improvers are additives to diesel fuel that, when added at low concentrations, boost the cetane number of the blend. The use of Cetane Number Improvers (CNI) enables the ignition quality of distillate stocks to be simply and economically increased. KAPL is one of the premium Cetane Improver Manufacturers in India.

CRISTOL Cetane Improver additives are designed for blending with diesel fuel to increase the cetane number by reducing ignition delay and hence improves diesel engine ignition. Shorter ignition delay period leads to more complete combustion and reduction in undesirable emissions.


CRISTOL 2-EHN reduces:

  • Ignition delay
  • Fuel consumption
  • Knock and noise
  • Misfiring
  • Exhaust emissions
  • Engine maintenance

At the same time better combustion results in:

  • Improved low temperature startability
  • Better warm up
  • Better ignition quality
