Abstract

The invention discloses safety efficient cleaning agent for an engine lubrication system. The safety efficient cleaning agent for the engine lubrication system comprises, by weight percent, 55-98.7% of base oil, 1-15% of carbon deposit dissolving agent, 0.1-10% of detergent, 0.1-10% of dispersant, and 0.1-10% of nanometer antiwear agent. The safety efficient cleaning agent can be used to clean deposits such as carbon deposit, colloid and grease inside an automobile engine, so that operation of the engine lubrication system is smoother, the engine can be maintained effectively, and service life of the engine is prolonged effectively. The safety efficient cleaning agent has the advantages that fire in cleaning can be prevented by using the high-flash-point carbon deposit dissolving agent and the base oil, and use is safer; the efficient purification dispersant is high in cleaning power and has high dispersing action against particulate carbon deposit cleaned off, and accordingly blockage of oil circuits is avoided; and by the aid of the nanometer antiwear agent, wear resistance of the cleaning agent is improved, scuffing of a cylinder bore in cleaning due to thinning of engine oil can be prevented, and poisoning of a three-way catalyst caused by sulphuric antiwear agent can also be prevented.

Description

technical field [0001] The invention relates to an engine disassembly-free cleaning agent, in particular to a safe and efficient engine lubricating system cleaning agent. Background technique [0002] During the use of the automobile engine lubrication system, deposits such as carbon deposits, colloids, and sludge will be formed. These deposits will not only affect the lubrication performance of the automobile engine, but also increase the wear and tear of the engine, thereby shortening the service life of the engine. Therefore, the interior of the automobile engine must be cleaned frequently to remove deposits such as carbon deposits, colloids and sludge formed inside the engine, improve the lubrication performance of the engine, and reduce the wear and tear caused by deposits. [0003] Chinese patent CN1232079 announced on October 20, 1999 discloses a kind of "automobile engine internal cleaning agent", which is composed of 10-20% aromatic hydrocarbons, 5-10% phenols, 4-8%...
