Air inlet system non-dismantling cleaning agent and preparation method thereof, and air inlet system cleaning method

Abstract

The invention discloses an air inlet system non-dismantling cleaning agent. The air inlet system non-dismantling cleaning agent comprises the following components in percentages by weight: 1 to 8% oftriethanolamine, 0.5 to 8% of oleic acid, 1 to 20% of a surfactant, 1 to 8% of an alkali retention agent, 2 to 20% of a solvent, 0.5 to 5% of an auxiliary cleaning agent and 55 to 90% of deionized water, wherein the weight percentages of all the components sum to 100% proportioning. The air inlet system non-dismantling cleaning agent provided by the invention has simple and easily-available components, can thoroughly clean difficultly-cleanable carbon deposit located at the back part of an air inlet valve in a form of foam under a condition of non-dismantling and an action of compressed air, and has high cleaning efficiency. The invention also discloses a preparation method for the air inlet system non-dismantling cleaning agent. The preparation method has the advantages of simple preparation process, simple and convenient operation and low cost. The invention also discloses an air inlet system cleaning method. The method specifically has significant cleaning effect to the carbon deposit of the air inlet valve of a gasoline direct injection vehicle, and has significant power reinforcing effect to an gasoline automobile engine.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to an air intake system disassembly-free cleaning agent, a preparation method thereof, and an intake system cleaning method using the cleaning agent. Background technique [0002] With the improvement of people's living standards, the popularity of automobiles is accelerating, and the demand for engine maintenance is also increasing. Limited by the characteristics of the existing cleaning agents for the engine intake system, the cleaning methods for the engine intake system are mainly summarized into the following three types: 1. Detachable cleaning; 2. Gasoline additive cleaning; 3. Hanging bottle cleaning . [0003] But, there is following defect in existing engine intake system cleaning method: [0004] (1) Disassembly cleaning is the most primitive and thorough cleaning method, but the disadvantage of this method is that disassembly takes a lot of man-hours and has a g...

Problems solved by technology

[0004] (1) Disassembly cleaning is the most primitive and thorough cleaning method, but the disadvantage of this method is that it takes a lot of time to disassemble and has a great impact on the fit between the original parts of the engine

[0005] (2) Gasoline additive-type cleaning has the advantages of no-disassembly and thorough cleaning for the removal of carbon deposits in the oil system. However, because the additives generally exert their cleaning effect at high temperatures, the cleaning effect on the intake valve is weak, especially For in-cylinder direct injection engines, because gasoline does not pass through the intake valve, it will cause carbon deposits on the intake valves to become a major drawback of direct injection vehicles, and additive cleaning is obviously not good for the carbon deposits on the intake valves of direct injection vehicles. may play a role

[0006] (3) The current bottle-type cleaning method in the market is to continuously send a certain amount of cleaning agent into the intake system to flush and clean the intake valve when the car is on the car, but this method is limited by the amount of cleaning agent and the bottom used. According to the actual market investigation, this method has no obvious cleaning effect on the carbon deposit in the intake valve.
