    What is the cetane number? - Sizes - The Online Quantinary℠

    Sep 06, 2005· cetane number. A rating on a scale used to indicate how quickly a fuel will ignite in a diesel engine, a figure of merit for diesel fuel as the octane number is a figure of merit for gasoline burned in spark ignition engines. A diesel engine run on a fuel with a lower cetane number than it was designed for will be harder to start, noisier, operate roughly and have higher emissions.

    Cetane number - Wikipedia

    Apr 11, 2017· "The cetane number of a given diesel is obtained by matching its ignition quality to a reference blend of cetane (set at 100) and isocetane (set at 15), hence the name 'cetane number.'

    AutoSpeed - Diesel cetane ratings

    This chemical can be produced from methanol and when used neat has a cetane rating between 55 and 60, compared to standard diesel in Europe at 51 and US #1 diesel at 44/45 and #2 diesel at 40, and Australian diesel with a minimum of 46.

    What is Diesel Fuel

    Abstract: Diesel fuel is a mixture of hydrocarbons obtained by distillation of crude oil.The important properties which are used to characterize diesel fuel include cetane number (or cetane index), fuel volatility, density, viscosity, cold behavior, and sulfur content.

    Diesel Fuel Cetane Number - Blending.GlobeCore
