Problems solved by technology

Adding water to diesel oil to make emulsified diesel oil can achieve the purpose of promoting complete combustion and saving diesel oil. There are a large number of patents and literature reports on this aspect of work. However, as an unstable system, emulsified diesel oil has poor storage performance and burns when used. Unstable, limiting its promotion and utilization
At present, there are also people who study renewable biomaterials such as grease to replace or partially replace traditional petroleum fuels to make biodiesel for daily use. However, the existing biodiesel has the following defects to varying degrees: ( 1) The current biodiesel must use high-quality animal and vegetable oils, such as soybean oil, peanut oil, etc. for esterification, and the price of raw materials is high, so it is difficult to popularize and utilize; High, the injection effect is poor, which affects the normal combustion; (3) The biodiesel made from oil contains colloid, which is easy to produce a large amount of carbon deposits and viscose during the combustion process in the combustion chamber, which sticks to the injector or deposits In the cylinder, thus affecting the normal operation of the engine
(4) When using biodiesel made of oil, due to its low volatility, it is not easy to atomize in the combustion chamber, which will easily cause problems such as difficult start-up and ignition delay in cold cars

Abstract

The micro-emulsified fatty acid diesel oil is proportionally prepared from fatty acid, naphthenic acid and diesel through mixing proportionally adding neutralizing alkali, water, ferrocene, triethanolamine and solvent oil No.200, and stirring. Its advantages are high mutual solubility to other oil, high stability and full combustion.

Description

technical field [0001] The invention relates to a diesel fuel, in particular to a microemulsion fatty acid diesel compounded by fatty acid, water and diesel. Background technique [0002] Based on people's concerns about the non-renewable oil resources and the increasing depletion, saving fuel and finding substitutes for oil products are the right choices for mankind to solve the fuel crisis. Adding water to diesel oil to make emulsified diesel oil can achieve the purpose of promoting complete combustion and saving diesel oil. There are a large number of patents and literature reports on this aspect of work. However, as an unstable system, emulsified diesel oil has poor storage performance and burns when used. Instability limits its promotion and utilization. At present, there are also people who study renewable biomaterials such as grease to replace or partially replace traditional petroleum fuels to make biodiesel for daily use. However, the existing biodiesel has the fol...
