AI Technical Summary

Benefits of technology

This new type of diesel engine lubricating agent can be made with specific chemical substances mixed together without any harmful impurities or residues found during production process. It also improves its stability over long periods at room temperature by reducing emissions caused by oxygen molecules produced through incomplete oxidative decomposition reactions between nitro groups on different atoms within certain amino acids (among other components).

Problems solved by technology

This patented technical solution describes how adding certain chemical agents like bicarbonates (BCO) helps stabilizing small particles called microspheres from liquid paraffin during burning process without causing damage on engines overall. Microcapsule diesel oils made by this method provide improved durability compared to traditional methods while reducing costs associated therewith.

Abstract

The invention relates to the field of petroleum and particularly relates to micro-emulsified diesel oil. The micro-emulsified diesel oil is prepared from the following components in parts by weight: 60-80 parts of 0# diesel oil, 8-15 parts of deionized water, 2-5 parts of block polymeric surfactant, 0.5-4 parts of sodium dioctyl sulfosuccinate, 1-5 parts of 1, 4-butanediol, 2-5 parts of n-butanol, 2-6 parts of isopropanol and 3-6 parts of isopropyl ketone. A micro-emulsified diesel oil additive provided by the invention has the following advantages that the block polymeric surfactant and sodium dioctyl sulfosuccinate as a cosurfactant are compounded, so that the micro-emulsification effect is better, a system is more stable, the micro-emulsified diesel oil prepared from the block polymeric surfactant and sodium dioctyl sulfosuccinate is longer in storage time up to over six months, free of layering, oil water separation and sediments, convenient to store and transport and high in practical value; when the micro-emulsified diesel oil burns, the discharge value of pollution gases is reduced during low-oxygen combustion.
