Problems solved by technology

[0007] However, there are not many gas gasoline engine lubricating oil additives currently on the market that can achieve good results in various functions.
and it's extremely expensive
And more is that the effect is average, and there are many single effects, and the effect of use is not ideal.

Abstract

A composite additive applied in fuel gas gasoline engine lubricating oil is basically characterized by being composed of a base oil, alkyl diphenylamine, calcium hydroxide, polyisobutylene, polyalkoxy polyol, polyacrylate, ethyoxyl phenol, phosphorodithioate, a boride based metal ceramic, copper oxide, and zinc oxide. The composite additive is scientific and reasonable, has quite strong repairing function on a wear surface of an engine, reduces the friction, reduces noise and increases sealing to a greatest extent, enhances power, extends the oil change period, and reduces exhaust gas emissions; the composite additive has the efficacy of significantly saving fuel oil. The environmental protection requirements are improved. The composite additive has various efficacies higher than those of other similar products.

Description

(1) Technical field [0001] The invention relates to a composite additive used in gas gasoline engine lubricating oil, in particular to a preparation scheme and a manufacturing method of the composite additive in gas gasoline engine lubricating oil. (2) Background technology [0002] At present, lubricating oil has made great progress, especially with the continuous development of society and the continuous advancement of science and technology, automotive lubricating oil is also constantly innovating, the purpose of which is to achieve better exhaust emissions from engines and various vehicles demanding. At present, engine oil occupies half of the lubricating oil market, among which gas gasoline taxis have basically been popularized in large and medium-sized cities. The gas gasoline engine lubricating oil additives can meet the needs of gasoline engine lubricating oil and natural gas engine lubricating oil at the same time. Therefore, it has been highly concerned by researc...
