Deposited carbon cleaning agent for internal-combustion engine

Abstract

The invention discloses a deposited carbon cleaning agent for an internal-combustion engine, which relates to an environmentally-friendly, safe and resource saving carbon deposit cleaning agent and comprises the following matters: 5 to 16 weight percent of polyoxyethylene ether surfactant, 5 to 10 weight percent of emulsifier, 0 to 5 weight percent of inorganic alkali, 0 to 4 weight percent of corrosion inhibitor and 65 to 90 weight percent of water. In the invention, the polyoxyethylene ether surfactant is used to soften the deposited carbon to make the attached deposited carbon loose and deformed; the emulsifier makes liquid penetrate the contact parts between the deposited carbon and parts easily, so that the deposited carbon can be stripped and the softening and cleaning effects of the product on the deposited carbon stains are improved; the inorganic alkali can decompose part of lipoid substance in the deposited carbon, so the cleaning effect is improved; and the corrosion inhibitor can reduce the corrosion of the parts in the cleaning process. The cleaning agent has excellent washing effect on deposited carbon on parts made of various materials. The cleaning agent uses water as a solvent instead of toxic solvent such as benzenes, phenol aromatic hydrocarbons and halogenated hydrocarbon. The prepared deposited carbon cleaning agent for the internal-combustion engine has the advantages of low cost, high detergency, quick deposited carbon removal and good effect.

Description

technical field [0001] The invention relates to a cleaning agent for carbon deposits on internal combustion engine components, in particular to an environment-friendly, safe and resource-saving carbon deposit cleaning agent. Background technique [0002] The internal combustion engine is used as a powered vehicle, such as automobiles, ships, locomotives, etc., after long-term operation, carbon deposits will be generated on the parts of the engine, and the carbon deposits will increase with the increase of the operating time of the engine. If the carbon deposits in the internal combustion engine system cannot be removed in time and effectively, it will not only affect the power and combustion effect of the internal combustion engine, but also reduce the service life of the internal combustion engine. [0003] Due to the different metal materials and coke properties of various parts of the engine, and the coke deposits on the internal combustion engine parts are relatively fir...

Problems solved by technology

Methods (1) and (2) have poor effect of removing carbon deposits and take a long time. The key is that it is easy to cause damage to parts

The main component of carbon deposits is colloid, which is closely combined with parts, and it is difficult to wash and remove with general solvents. Method (3) use gasoline, benzene, phenolic aromatics, diesel, halogenated hydrocarbons, etc. as solvents for washing. Large, poor washing effect, poor environmental compatibility, safety hazards such as flammability and explosion, and high toxicity, which is quite harmful to the health of operators
