Carbon deposit cleansing agent of engine and preparation method of carbon deposit cleansing agent

Abstract

The invention belongs to the field of cleansing agents of an engine, and particularly relates to a carbon deposit cleansing agent of an engine and a preparation method of the carbon deposit cleansingagent. The carbon deposit cleansing agent comprises the following raw materials in parts by mass of 28-64 parts of diethylene glycol ether acetate, 28-65 parts of diethylene glycol monophenyl ether, 28-65 parts of N-methyl pyrrolidone, 2-8 parts of a lactic acid solution, 1-5 parts of Long-chain carboxylate polyoxyethylene-18, 1-6 parts of isothiazolinone, and 1-9 parts of an alkaline solution. The carbon deposit cleansing agent disclosed by the invention adopts a manner that a positive ion surface active agent is collocated with the diethylene glycol ether acetate, the diethylene glycol monophenyl ether and the N-methyl pyrrolidone, so that the problems that in the prior art, when carbon deposit is washed with a solvent, an anionic surface active agent and a plasticizer, each component ofthe engine is subjected to dual corrosion, the engine coating is peeled off, and ternary noble metals are peeled off are effectively solved; the engine carbon deposit cleansing agent is friendly to environment and the engine; and the carbon deposit removing effect is good, and the effect of instantly peeling the carbon deposit off can be achieved.

Description

technical field [0001] The invention relates to the field of engine cleaning agents, in particular to an engine carbon deposit cleaning agent and a preparation method thereof. Background technique [0002] Engine carbon deposits refer to the residues produced after the fuel and lubricating oil are combusted together, which are easily deposited and adsorbed on the intake manifold, throttle valve, valve, combustion chamber, piston, spark plug, fuel injector, three-way catalytic converter, etc. , Excessive carbon deposits will cause difficulty in cold start of the engine, poor engine air intake, jittering, unstable idle speed, increased fuel consumption after the engine is overheated, and easy to cause problems such as overheating and burning parts. The carbon deposition deposits at the above positions are generally cationic adsorbents. The cations are losing one or several electrons, making the outermost electrons reach a stable structure of 8 or 2 electrons. The atoms with la...

Problems solved by technology

Although this type of cleaning agent is neutral and has a certain cleaning effect on the carbon deposits in the combustion chamber, due to the excessive use of diethylene glycol butyl ether acetate solvent, it will cause the rapid diffusion of anionic surfactants, resulting in dryness of the metal surface , even if the lubricating oil is sprayed on the cleaned metal surface, it will produce metal surface stress microcracks on the metal surface of the ferroalloy engine, all-aluminum engine, and magnesium-aluminum engine, especially when the car engine is driven for more than 1,000 kilometers after cleaning. The resulting microcracks will be particularly noticeable! In addition, after the cleaning agent cleans the three-way catalytic converter of the engine, the plasticizer isooctyl alcohol in the cleaning agent will make platinum, palladium, rhodium and the three precious metals of the three-way catalytic converter and the engine coating Gradually speed up the shedding!

[0004] Therefore, after cleaning the engine with such cleaning agents for a long time, it will damage the safe use of the engine, and at the same time, it is easy to cause the engine to exceed the emission standard and continue to pollute again!
