Description
Technical Field
The invention relates to the technical field of automobile cleaning, in particular to a carbon deposit cleaning composition for an engine of a fuel engine and a using method thereof.
Background
In the working process of an automobile engine, fuel additives, pollutants in air and lubricating oil residues are burned for a long time at high temperature to easily generate carbon deposition and are distributed on the surfaces of a cylinder, a piston and a piston ring, so that the piston cannot timely scrape the lubricating oil clean to cause the phenomenon of engine oil burning. At the same time, these deposits are trapped in the fuel intake system, intake valves, or combustion chambers of the engine, causing uneven or insufficient fuel supply in the engine cylinders, resulting in poor engine performance, increased emissions, and poor fuel economy.
The carbon deposit is relatively complex in components and mainly contains hydroxy acid, asphaltene, oil coke, ash and the like. The carbon deposit attachments are generally cation attachments, cations of the carbon deposit attachments lose one or more electrons, so that the number of the electrons at the outermost layer of the carbon deposit attachments reaches a stable structure of 8 or 2 electrons, the larger the atomic radius of atoms, the stronger the electron losing capability of the atoms, the stronger the carbon deposit cation deposits are tightly adsorbed on the metal surface, and the carbon deposit cation deposits are often difficult to clean when being tightly adsorbed on the surface of an inner cavity part of an engine.
After the carbon deposit is formed, the normal operation of the engine can be seriously influenced, the power of the engine is reduced, the carbon deposit can cause local overheating, and a piston can be damaged in serious cases. In order to protect the normal work of the engine and prolong the service life of the engine, the method for removing the carbon deposit from the engine is an economic and effective method.
At present, the cleaning method of carbon deposition mainly comprises a mechanical method and a chemical method. The mechanical method generally comprises mechanical tool cleaning and soft and hard abrasive particle cleaning, the method has low productivity, carbon deposition on the part which is difficult to contact with the tool is not easy to completely remove, scratches are left on the surface and become new carbon deposition to form a center; the chemical method adopts a cleaning agent to remove the carbon deposit, and generally adopts strong alkali and strong acid to clean, which can cause irreversible damage to the alloy layer of the part.
