Oil nozzle cleaning agent and preparation method thereof

Abstract

The invention discloses an oil nozzle cleaning agent and a preparation method thereof. The oil nozzle cleaning agent is prepared from, by mass, 5-15% of an additive, 20-40% of solvent oil, 35-50% of xylene, 5-20% of methyl isobutyl carbinol, 2-15% of petroleum ether and 0-0.01% of color mixing powder. The additive is prepared from, by mass, 20-30% of polyether amine, 15-30% of heavy solvent naphtha, 1-10% of light solvent naphtha, 10-30% of polyether glycol, 1-10% of 2-ethylhexanol, 1-10% of trimethylbenzene, 0.5-5% of naphthalene, 0.5-5% of n-propyl benzene, 0.5-5% of polypropylene glycol, 0.05-3% of cumene and 0.01-5% of triethanolamine. The oil nozzle cleaning agent is capable of clearing carbon deposit in oil nozzles to improve oil atomizing effects, and oil consumption reduction, power recovery and improvement of difficulty in cold starting are realized.

Description

technical field [0001] The invention belongs to the technical field of gasoline additives, and in particular relates to a fuel injection nozzle cleaning agent and a preparation method thereof. Background technique [0002] With the rapid development of the automobile industry, the number of automobiles in our country is increasing rapidly. As automobiles bring convenience to people's production and life, they also increase the consumption of petroleum resources and the emission of harmful exhaust substances. When the car is running, the engine intake system and the combustion chamber produce a large amount of deposits, which seriously affects the normal fuel injection, atomization and mixed combustion, resulting in unstable idle speed, poor acceleration performance and increased fuel consumption. The emission of harmful gases such as hydrocarbons, CO and NO increases, and the fuel injector deposits can also cause local overheating, pre-ignition and knocking to make the comb...

AI Technical Summary

Problems solved by technology

[0003] Carbon deposits in intake valves and three-way catalytic converters will cause many hazards: (1) It is difficult to start cold at low temperatures, and the idle speed of cold cars cannot reach the specified speed. ) The air intake resistance of the engine increases, the engine power decreases, and knocking is caused in severe cases; (3) The driving performance becomes poor; (4) The service life of spark plugs, oxygen sensors, and three-way catalytic converters is shortened; (5) Incomplete combustion of gasoline , poor acceleration, increased fuel consumption, increased exhaust emissions, and shortened engine life

[0004] The common solution is to use gasoline cleaning agent during maintenance, and the current commercially available solvent-based cleaning agent has a certain swelling effect on the rubber and plastic parts of the pipeline, which will affect the sealing performance and service life of the oil circuit; the commercially available cleaning agent The cleaning effect is not good, and the cleaning efficiency is low

Various existing fuel injector cleaning agents have their own advantages and disadvantages, but the comprehensive performance of the existing fuel injector cleaning agents in the removal of carbon deposits in the oil circuit and fuel saving rate is always unsatisfactory
