An automobile engine cleaning agent and a using method thereof

Abstract

The invention relates to the technical field of cleaning agents and the technical field of using methods of the cleaning agents, and particularly relates to an automobile engine cleaning agent and a using method thereof. According to the automobile engine cleaning agent and the using method thereof, cleaning is thorough, thus reducing the oil consumption and prolonging the service lifetime of vehicles. No protective agent is needed after cleaning processes, and a crankshaft oil seal and a valve-chamber cover periphery are free from oil leakage phenomena. The automobile engine cleaning agent comprises following components by weight: 11%-17% of kerosene, 0.5%-2% of alcohol, 0.5%-1.0% of a thickening agent methacrylic acid, 0.1%-1.0% of a corrosion inhibitor cetylamine, 0.4%-1.0% of an emulsifier calcium stearoyl lactate, 0.5%-1.5% of an antiwear additive calcium borate, 0.5%-1.0% of N,N'-bis(salicylidene) diaminopropane, 0.5%-1.5% of a surfactant sodium dodecylsulfate and 80% of engine oil.

Description

technical field [0001] The invention relates to the technical field of cleaning agent and its application method, in particular to a cleaning agent used on automobile engines and its application method. Background technique [0002] As we all know, an engine is a machine that converts a certain form of energy into mechanical energy; its function is to convert the chemical energy of liquid or gas into heat energy after combustion, and then convert the heat energy into mechanical energy through expansion and output power externally. The power comes from the engine; after the car engine is used for a period of time, that is, after 40,000 to 50,000 kilometers or after driving for 4 years, polymers will be produced inside the engine, such as: carbon deposits, colloids, waxy and sludge; The used car will have varnish on the cylinder wall and metal surface, so the running resistance of the car engine will increase, and then the fuel consumption will increase; through long-term foll...

[0002] As we all know, an engine is a machine that converts a certain form of energy into mechanical energy; its function is to convert the chemical energy of liquid or gas into heat energy after combustion, and then convert the heat energy into mechanical energy through expansion and output power externally. The power comes from the engine; after the car engine is used for a period of time, that is, after 40,000 to 50,000 kilometers or after driving for 4 years, polymers will be produced inside the engine, such as: carbon deposits, colloids, waxy and sludge; The used car will have varnish on the cylinder wall and metal surface, so the running resistance of the car engine will increase, and then the fuel consumption will increase; through long-term follow-up investigations, it is found that throttle valves, fuel injectors, fuel distributors and When the spark plugs can work normally, if the fuel consumption is too high during the driving of the vehicle, it will deviate from the normal value (mainly because there are too many impurities and attachments inside the engine, which lead to increased running resistance, especially between the crankshaft and the connecting rod and the tiles. Excessive sticky matter)

And the existing cleaning engine method is mainly ultrasonic cleaning, special cleaning machine and cleaning oil (agent), these methods all have the drawback that cleaning is not thorough more or less

[0003] Among them, the cleaning oil (agent) type cleaning is to pour the cleaning agent into the oil tank and run the car for about 20 minutes for cleaning. Because the cleaning time is too short and the cleaning steps are too simple, the cleaning effect is not ideal.

The polymer inside the engine is not formed in a day or two, but is formed by the polymerization of impurities inside the fuel and lubricating oil after the engine has been exposed to high temperature and high pressure for a long time. However, the short cleaning time of the above-mentioned cleaning method is also inherent. If the cleaning time is long, there will be adverse consequences. For example, the oil leakage of the crankshaft oil seal and the valve cover will not be found at the time, but the above phenomenon will occur after one or two months, that is, the sequelae of cleaning the engine; Wash the engine at the cleaning site; moreover, after cleaning the engine, in order to better protect the engine, it is necessary to add a protective agent, which will cause a lot of damage to the metal surface during the cleaning process
