Abstract

The invention discloses an engine carbon deposit combustion cleaning agent. The engine carbon deposit combustion cleaning agent is prepared from the following raw materials in percentage by weight: 60% to 80% of dibutyl carbonate, 0.2% to 1.5% of benzotriazole, 0.5% to 2.5% of mixed cresol, 3% to 8% of mixed trimethylbenzene, 3% to 8% of ethylene glycol monobutyl ether, 5% to 15% of n-octanol and 2% to 5% of cyclohexanol. In addition, the invention further discloses a preparation method for the cleaning agent. The engine carbon deposit combustion cleaning agent disclosed by the invention can be used for slowly and gradually stripping hard carbon deposits during the running of an automobile, effectively cleaning stubborn carbon deposits from all parts of an engine and recovering normal functions of the engine; meanwhile, the content of HC in automobile exhaust gas is lowered by 85% or more, the content of CO is lowered by 67% or more, the content of PM2.5 is lowered by 75% or more, and the exhaust emissions reach national V standards; the engine carbon deposit combustion cleaning agent has high octane number and cetane number and has the flash point above 55 DEG C, thereby being capable of being applied to diesel oil and gasoline.

Description

technical field [0001] The invention belongs to the technical field of engine carbon deposit cleaning agents, and in particular relates to an engine carbon deposit combustion cleaning agent and a preparation method thereof. Background technique [0002] With the continuous development of the automobile industry, automobile engines have higher and higher requirements on fuel quality. However, the content of olefins in domestic motor gasoline is relatively high, and it is easy to form colloids during storage and transportation, resulting in incomplete combustion of the engine and carbon deposits, resulting in unstable working conditions of the engine; decreased power, increased fuel consumption, clogging of the three-way catalyst, and exhaust gas CO and HC harmful substances and PM2.5 increase. Add engine carbon deposit combustion cleaner, which can effectively infiltrate, strip, and burn off engine carbon deposits, improve combustion efficiency, reduce exhaust emissions of h...
