Gasoline detergent and application and preparation method thereof

Abstract

The invention discloses a gasoline detergent and application and a preparation method thereof. The gasoline detergent is prepared from the following components in percentage by mass: 30 to 60 percentof light solvent naphtha, 0.05 to 5 percent of heavy solvent naphtha, 15 to 35 percent of polyetheramine, 5 to 45 percent of trimethylbenzene, 0.5 to 8 percent of n-propylbenzene, 0.5 to 8 percent ofxylene, 0.5 to 8 percent of 2-ethylhexanol and 0.5 to 8 percent of isopropyl benzene. The detergent and the modifier of the invention contain polar activating factors which can adsorb, permeate and peel off colloidal sludge and carbon deposit and are discharged along exhaust gas after being burned at a high temperature, thereby cleaning an entire fuel system; the problems of difficult cold start,unstable idling, unsmooth acceleration and the like which are caused by the carbon deposit are solved. The gasoline detergent is safe and environmentally friendly, does not contain alcohol substancesand cannot corrode or damage an engine part.

Description

technical field [0001] The invention belongs to the technical field of gasoline additives, in particular to a gasoline detergent and its application and preparation method. 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 deposits in the combustion chamber can also cause local overheating, pre-ignition and knocking to make the combustion e...

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 improver or detergent during maintenance, but the current commercially available solvent-based detergent 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 cleaning effect of the sold detergent is not good, and the cleaning efficiency is low

Various existing gasoline detergents have their own advantages and disadvantages, but the existing gasoline detergents do not have a good power-enhancing effect, and the comprehensive performance of removing carbon deposits in the oil circuit and fuel saving rate is always unsatisfactory
