Technical Field

The invention relates to an automobile engine cleaning agent and a preparation method and application thereof.

Background

The automobile engine is an engine for providing power for an automobile and is the heart of the automobile; when the engine does high-speed relative motion, all metal contact surfaces need to be lubricated by lubricating oil; however, because the automobile engine is precise in structure and very sensitive to the existence of tiny deposits such as oil sludge, carbon deposition, and gelatinous substances, even if the engine oil is frequently replaced, the oil sludge, the carbon deposition, and the gelatinous substances cannot be cleaned, and the oil sludge, the carbon deposition, and the gelatinous substances have direct influence on the service life of the engine; therefore, the cleaning of harmful chemical substances such as carbon deposit, oil sludge, gelatinous substance and the like of the engine is particularly important for subsequent power of the automobile engine. The cleaning oil (agent) type cleaning is to pour the cleaning agent into the engine oil tank and to run for about 20 minutes to clean, and because the cleaning time is too short and the cleaning step is too simple, the cleaning effect is not ideal. The polymer in the engine is not generated in one or two days, but is formed by polymerizing impurities in fuel oil and lubricating oil under high temperature and high pressure for a long time, but the cleaning method is short in cleaning time and inherent in the reason that the existing cleaning agent is used, the long cleaning time has adverse effects, such as oil leakage of a crankshaft oil seal and a valve chamber cover, can not be found at some time, but the phenomenon can be generated after one or two months, namely the sequela of cleaning the engine; the other method is that the engine is washed and pulled to be a cylinder tile on the washing site; moreover, after the engine is cleaned, a protective agent needs to be added for better protecting the engine, so that the metal surface is not damaged in the cleaning process.
