Problems solved by technology

However, there is a reason for the short cleaning time of the above-mentioned cleaning method, because using the existing cleaning oil, there will be adverse consequences if the cleaning time is long. , but after one or two months, the above phenomenon will appear, that is, the sequelae of cleaning the engine; some of them are cleaning the engine at the cleaning site; moreover, after cleaning the engine, in order to better protect the engine, it is necessary to add Protective agent, which will cause considerable damage to the metal surface during cleaning

Abstract

The invention relates to the field of automobile engine cleaning, especially to automobile engine dismantling-free cleaning oil and application thereof. The cleaning oil comprises, by weight, 15-21% of kerosene, 0.6-1.5% of an antiwear additive, 0.8-2.5% of ethanol, 0.6-1.0% of a metal deactivator, 0.6-1.5% of a thickening agent, 0.6-1.5% of a surfactant, 0.2-1.0% of a corrosion inhibitor, 0.6-1.0% of an emulsifier and 75% of engine oil. During cleaning, the cleaning oil is added to the upper limit of an oil level gauge of an empty automobile engine; the automobile is started discontinuously at idle speed; the above steps are repeated, and cleaning mixture is discharged; and the above steps are repeated twice, and cleaning mixture obtained at each time is discharged. According to the invention, inner cavity of an engine can be thoroughly cleaned; oil consumption of automobiles is reduced; service life of vehicles is prolonged; there is no need to add a protective agent; and oil leakage will not be caused.

Description

technical field [0001] The invention relates to the field of automobile engine cleaning, in particular to an automobile engine disassembly-free cleaning oil and its application. [0002] technical background [0003] After the car engine is used for a period of time, that is, after 40,000 to 50,000 kilometers or 4 years of driving, polymers will be produced inside the engine, such as: carbon deposits, gums, waxes and sludge. Cars that have not been used for a long time will have varnish on the cylinder wall and metal surface, which will increase the running resistance of the car engine, and then increase the fuel consumption. Through a long-term follow-up investigation, it was found that when the throttle valve, fuel injector, fuel distributor and spark plug can all work normally, if the fuel consumption is too high and deviates from the normal value during driving, it is because the impurities and attachments inside the engine are too high. It often leads to increased runni...
