The cetane number of diesel oil is a main index representing the antiknock property of diesel oil. The knocking and surface phenomena of the diesel engine are similar to those of the gasoline engine, and the knocking and surface phenomena are caused by different reasons. While both knock originates from the auto-ignition of the fuel, diesel knock is due to the fact that, contrary to gasoline engines, diesel is not readily auto-ignited and fuel accumulates too much in the cylinders at the onset of auto-ignition. Thus, the cetane number of diesel fuel also represents the naturalness of diesel fuel. The diesel engine uses high diesel oil, and has uniform combustion, high thermal power and fuel saving. Generally, light diesel oil with a cetane number of 45-50 is suitable for high speed diesel engines with a rotation speed of 1000 revolutions per minute, and heavy diesel oil with a cetane number of 35-49 is suitable for medium and low speed diesel engines with a rotation speed of less than 1000 revolutions.
The kerosene is also called as kerosene, a hydrocarbon mixture with 10-16 carbon atoms, and belongs to a light petroleum product; colorless to pale yellow oily liquid; the boiling point range is 180-310 ℃, and the relative density is about 0.8; is insoluble in water and soluble in organic solvent; the steam can form an explosive mixture with air, and the explosion limit is 0.7-5.0%; is mainly prepared by refining kerosene fraction obtained by crude oil distillation.
Isooctyl nitrate is a diesel oil additive, used for improving the cetane number of diesel oil and improving the combustion performance of diesel oil.
The pure oleic acid of the vegetable oleic acid is colorless oily liquid and has the smell of animal oil or vegetable oil, the color of the pure oleic acid gradually becomes dark after being placed in the air for a long time, and the industrial product is yellow to red oily liquid and has the smell of lard oil.
The methanol diesel oil is a novel environment-friendly clean fuel prepared by blending diesel oil, methanol and an additive according to a certain volume or mass ratio through a strict flow. The methanol diesel oil is an environment-friendly energy-saving fuel prepared by adding a certain proportion (15%, 50%, 90%) of denatured fuel methanol into national standard light diesel oil according to volume or weight ratio. The methanol diesel oil has the characteristics of high cleanness and low emission.
The diesel oil belongs to oils, the methanol belongs to alcohols, the calorific value of the methanol is low, and the methanol and the diesel oil cannot be mutually dissolved. The vegetable oleic acid and the n-octanol have the effect of mutual solubility, and form the methanol diesel oil after mutual solubility, and the cetane number of the methanol diesel oil is improved by adding other additive raw materials used in the invention; the viscosity of the methanol diesel oil is improved; the density of the methanol diesel oil is improved; the flash point of the methanol diesel is improved; the power of the methanol diesel is improved; the distillation range of the methanol diesel oil is reduced.
