Abstract

The invention provides an engine carbon deposit cleaning composition, and the composition comprises the following components in percentage by weight: (a) 3-10% of oleylamine; (b) 0-60 wt% of a fatty alcohol polyoxyethylene ether modified organosilicon surfactant; (c) 30-83% by weight of pyrrolidone; (d) 5-67 wt% of ethylene glycol butyl ether; (e) 0-20% by weight of water. The engine carbon deposit cleaning composition has good carbon deposit cleaning capacity and good metal corrosion resistance.

Description

technical field [0001] The invention relates to a composition for cleaning engine carbon deposits, a method for preparing the composition for cleaning engine carbon deposits, and a method for cleaning engine carbon deposits. Background technique [0002] Car engines are prone to carbon deposits (also known as "carbon deposits") during work. These carbon deposits are usually formed at high temperatures from substances in the fuel, fuel decomposition products, fuel combustion products, airborne pollutants not removed by filtration, and lubricating oil residues, and remain in the engine's fuel introduction system, further valve or combustion chamber. Carbon deposits in automobile engines can cause uneven or insufficient fuel delivery in the engine cylinders, resulting in poor engine performance, increased emissions, and poor fuel combustion efficiency. [0003] Existing some cleaning agents that can be used to remove engine carbon deposits in the prior art. For example, US29...
