Embodiment 1

[0012] An engine repair agent, composed of base fluid; polyisobutylene; dialkyl dithiophosphate; phosphite; tert-butylated phenyl phosphate; alkyl methacrylate copolymer. The base fluid is kerosene. The weight percent of each component is 70% of kerosene; 3% of polyisobutylene; 6% of dialkyl dithiophosphate; 5% of phosphite; 12% of tert-butylated phenyl phosphate; Copolymer 4%. The above-mentioned polyisobutylene; dialkyl dithiophosphate; phosphite; tert-butylated phenyl phosphate; alkyl methacrylate copolymer. Put each component into an airtight container for mixing, heat to 65-70°C, and stir for 120 minutes. When the temperature is lowered to 55-60°C, add the above-mentioned kerosene and stir for 30 minutes. The product is released after filtering.

[0013] Add 2% of this product to the fuel tank each time, and add it to the fuel tank at the same time. The effect has the following advantages after testing:

[0014] 1. Engine noise is significantly reduced. No vibration...

Embodiment 2

[0019] An engine repair agent, composed of base fluid; polyisobutylene; dialkyl dithiophosphate; phosphite; tert-butylated phenyl phosphate; alkyl methacrylate copolymer. The base fluid is kerosene. The weight percent of each component is 61% of kerosene; 5% of polyisobutylene; 8% of dialkyl dithiophosphate; 6% of phosphite; 14% of tert-butylated phenyl phosphate; Copolymer 6%. The above-mentioned polyisobutylene; dialkyl dithiophosphate; phosphite; tert-butylated phenyl phosphate; alkyl methacrylate copolymer. Put each component into an airtight container for mixing, heat to 65-70°C, and stir for 180 minutes. When the temperature is lowered to 55-60°C, add the kerosene in the above proportion and stir for 30 minutes. The product is released after filtering.

[0020] Add 2% of this product to the fuel tank each time, and add it to the fuel tank at the same time. The effect has the following advantages after testing:

[0021] 1. Engine noise is significantly reduced. No v...

Abstract

The invention discloses an engine repair agent, which is basically characterized by comprising the following components in percentage by weight: 3 to 5 percent of polyisobutene, 6 to 8 percent of dialkyl dithiophosphate, 5 to 6 percent of phosphite ester, 12 to 14 percent of tert-butylphenyl phosphate, 4 to 6 percent of methacrylic acid alkyl ester copolymer and the balance of basic solution. The method is simple and practical; the prepared repair agent has obvious effect of repairing engines; and the product has low cost, has higher effect than similar products, can prolong the service life of the engines, and is environment-friendly and energy-saving.

Description

(1) Technical field [0001] The invention relates to an engine additive, in particular to an engine repair agent. (2) Background technology [0002] An additive is a material that imparts and enhances the performance of a lubricating oil. With the continuous development of engine technology, the introduction of various new technologies has also put forward higher requirements on the properties and performance of various lubricating oils. One of the current driving forces for the development of various types of lubricants is to protect the environment. And the current use of various lubricating oil additives has indeed improved certain performances of the engine, but it is also true that some additives have seriously affected the normal operation of the engine. Some additives cause corrosion and oxidation to the engine, and some additives form more carbon deposits on the engine. Although some additives on the market have certain effects, they do not meet the requirements of...
