  2. Calculated Carbon Aromaticity Index - Wikipedia

    en.wikipedia.org/wiki/Calculated_Carbon_Aromati...

    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 fuels the cetane numbers are used. Cetane numbers are tested using a special test engine and the existing engine was not made ...

  3. Oil analysis - Wikipedia

    en.wikipedia.org/wiki/Oil_analysis

    Oil sampling is a procedure for collecting a volume of fluid from lubricated or hydraulic machinery for the purpose of oil analysis. Much like collecting forensic evidence at a crime scene, when collecting an oil sample, it is important to ensure that procedures are used to minimize disturbance of the sample during and after the sampling process.

  4. Total base number - Wikipedia

    en.wikipedia.org/wiki/Total_Base_Number

    Base Number (BN) is a measurement of basicity that is expressed in terms of the number of milligrams of potassium hydroxide per gram of oil sample (mg KOH/g). BN is an important measurement in petroleum products, and the value varies depending on its application.

  6. Diesel fuel - Wikipedia

    en.wikipedia.org/wiki/Diesel_fuel

    A tank of diesel fuel on a truck. Diesel fuel, also called diesel oil, heavy oil (historically) or simply diesel, is any liquid fuel specifically designed for use in a diesel engine, a type of internal combustion engine in which fuel ignition takes place without a spark as a result of compression of the inlet air and then injection of fuel.

  7. Motor oil - Wikipedia

    en.wikipedia.org/wiki/Motor_oil

    An oil pump, a vane or gear pump powered by the engine, pumps the oil throughout the engine, including the oil filter. Oil filters can be a full flow or bypass type. In the crankcase of a vehicle engine, motor oil lubricates rotating or sliding surfaces between the crankshaft journal bearings (main bearings and big-end bearings) and rods ...

  8. Diesel exhaust fluid - Wikipedia

    en.wikipedia.org/wiki/Diesel_exhaust_fluid

    Diesel exhaust fluid (DEF; also known as AUS 32 and sometimes marketed as AdBlue [3]) is a liquid used to reduce the amount of air pollution created by a diesel engine. Specifically, DEF is an aqueous urea solution made with 32.5% urea and 67.5% deionized water .

  9. Crude oil assay - Wikipedia

    en.wikipedia.org/wiki/Crude_oil_assay

    The results of crude oil assay testing provide extensive detailed hydrocarbon analysis data for refiners, oil traders and producers. Assay data help refineries determine if a crude oil feedstock is compatible for a particular petroleum refinery or if the crude oil could cause yield, quality, production, environmental and other problems.
