  2. Crankcase dilution - Wikipedia

    en.wikipedia.org/wiki/Crankcase_dilution

    Crankcase dilution is caused more when the lube oil is fresher. [3] Another cause of crankcase dilution is a slow or delayed injection cycle. [2] This causes the timing to be thrown off and the oil is most likely to enter the crankcase at this point. Water and dirt can also further the effects of crankcase dilution. [1]

  3. History of gasoline - Wikipedia

    en.wikipedia.org/wiki/History_of_gasoline

    One journal stated, "on a multi-cylinder engine in a high-priced car we are diluting the oil in the crankcase as much as 40 percent in a 200-mile [320 km] run, as the analysis of the oil in the oil-pan shows". [32]

  4. Two-stroke oil - Wikipedia

    en.wikipedia.org/wiki/Two-stroke_oil

    The oil is dyed blue to make it easier to recognize in the gasoline. It appears black in this bottle because it is not diluted. Two-stroke oil (also referred to as two-cycle oil, 2-cycle oil, 2T oil, or 2-stroke oil) is a special type of motor oil intended for use in crankcase compression two-stroke engines, typical of small gasoline-powered ...

  5. Types of plant oils - Wikipedia

    en.wikipedia.org/wiki/Types_of_plant_oils

    There are three primary types of plant oil, differing both the means of extracting the relevant parts of the plant, and in the nature of the resulting oil: Vegetable fats and oils were historically extracted by putting part of the plant under pressure, squeezing out the oil. Macerated oils consist of a base oil to which parts of plants are added.

  6. Steam cracking - Wikipedia

    en.wikipedia.org/wiki/Steam_cracking

    An ethylene plant, once running, does not need to import steam to drive its steam turbines. A typical world scale ethylene plant (about 1.5 billion pounds (680 KTA) of ethylene per year) uses a 45,000 horsepower (34,000 kW) cracked gas compressor, a 30,000 hp (22,000 kW) propylene compressor, and a 15,000 hp (11,000 kW) ethylene compressor.

  7. Edible oil refining - Wikipedia

    en.wikipedia.org/wiki/Edible_oil_refining

    Edible oil refining is a set of processes or treatments necessary to turn vegetable raw oil into edible oil.. Raw vegetable oil, obtained from seeds by pressing, solvent extraction, contains free fatty acids and other components such as phospholipids, waxes, peroxides, aldehydes, and ketones, which contribute to undesirable flavor, odor, and appearance; [1] for these reasons, all the oil has ...

  8. Exhaust gas recirculation - Wikipedia

    en.wikipedia.org/wiki/Exhaust_gas_recirculation

    The end result of this recirculation of both exhaust gas and crankcase oil vapour is again an increase in soot production, which however is effectively countered by the DPF, which collects these and in the end will burn those unburnt particles during regeneration, converting them into CO2 and water vapour emissions, that - unlike NOx gases ...

  9. Hydrotreated vegetable oil - Wikipedia

    en.wikipedia.org/wiki/Hydrotreated_vegetable_oil

    In addition, all of these green diesels can be introduced into any diesel engine or infrastructure without many mechanical modifications [13] at any ratio with petroleum-based diesels. [10] Renewable diesel from vegetable oil is a growing substitute for petroleum. [14]
