Low sulfur diesel lubricant

Abstract

The invention belongs to the technical field of fuels, and in particular relates to a low sulfur diesel lubricant which is made from the following raw materials by weight: 40-80 parts of polyols, 15-30 parts of Isocarbamide, 10-20 parts of Triisopentylamine and 1-10 parts of vinyl n-butyl ether. The low sulfur diesel lubricant can make the lubrication effect of low sulfur diesel oil good, and does not affect the performance of the diesel oil, can be added to the low sulfur diesel oil, and can adapt to various diesel engines.

Description

technical field [0001] The invention belongs to the field of fuel technology, in particular to a low-sulfur diesel oil lubricant. Background technique [0002] From January 1, 2018, national automotive diesel will implement the national standard, requiring the mass fraction of sulfur to be less than 10 μg / g. Low-sulfur and ultra-low-sulfur diesel generally adopt a harsh hydrogenation process. During the refining process of diesel, while removing sulfide, it also removes highly polar aromatic heterocyclic compounds, nitrogen-containing polar compounds and acidic substances, etc. Effective anti-wear components are removed, resulting in poor lubricity of diesel oil. This leads to excessive wear of fuel injection pumps such as rotary pumps and reciprocating pumps (In-line Pumps) that rely on diesel self-lubrication, which greatly reduces the service life of the fuel injection system. At the same time, there are also problems such as insufficient engine power, poor fuel atomiza...

Problems solved by technology

Low-sulfur and ultra-low-sulfur diesel generally adopt a harsh hydrogenation process. During the refining process of diesel, while removing sulfide, it also removes highly polar aromatic heterocyclic compounds, nitrogen-containing polar compounds and acidic substances, etc. Effective removal of anti-wear components, resulting in poor lubricity of diesel oil

This leads to excessive wear of fuel injection pumps such as rotary pumps and reciprocating pumps (In-line Pumps) that rely on diesel self-lubrication, which greatly reduces the service life of the fuel injection system

At the same time, there are also problems such as insufficient engine power, poor fuel atomization and fuel pump failure.
