Cleaning fluid for oil way and gas way of vehicle

Abstract

The invention provides cleaning fluid for an oil way and a gas way of a vehicle. Aqueous solvent comprises, by volume percentage, 5%-15% of hydrochloric acid or sulfamic acid with the mineral acid concentration ranging from 29% to 31%, 3%-10% of surface active agent sodium dodecyl sulfate, 1%-5% of sodium polyphosphate, 2%-10% of corrosion inhibitor isoquinoline quaternary ammonium salt, 2%-10% of Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium, 1%-5% of chelating agent cetyl trimethyl ammonium bromide and 50%-60% of water. The cleaning fluid is the aqueous solvent prepared by mixing the above ingredients. An air inlet system, a combustion system and an exhausting system of an engine can be cleaned forcefully. Restrictor and combustor sediments are removed, and chemical complexes which are adhered to an oxygen sensor and a three-way catalyst are removed. The chemical complexes and deposited carbon adhered to the three-way catalyst is dredged, the purifying performance of the three-way catalyst for exhaust is recovered, and the service life of the three-way catalyst is prolonged.

Description

technical field [0001] The invention belongs to the technical field of automobiles, in particular to an automobile oil and gas path cleaning fluid. Background technique [0002] When the automobile engine exhausts through the exhaust pipe, when the three gases of carbon monoxide, hydrocarbons and nitrogen oxides pass through the three-way catalytic converter of the automobile, the grids with rare metals such as rhodium, platinum, and palladium as catalysts are respectively spaced apart, and the gas is enhanced. The activity of the three gases, through the combustion in the three-way catalytic converter of the car, undergoes a redox chemical reaction, in which carbon monoxide is oxidized into colorless and non-toxic carbon dioxide gas at high temperature, hydrocarbons are oxidized into water and carbon dioxide, nitrogen and oxygen at high temperature The compounds are reduced to nitrogen and oxygen at high temperatures, allowing the exhaust gas to be purified. The temperatur...

Problems solved by technology

The temperature at which it starts to work is about 200°C, and the best working temperature is 400-800°C. After exceeding 1000°C, the rare and precious metal components used as catalysts will also undergo chemical changes, so that the three-way catalytic converter grille of the car The effective catalyst composition is reduced, and the catalytic effect is weakened. Due to the oxidation-reduction chemical reaction, heat will be generated. Under normal engine conditions, when the content of carbon monoxide and hydrocarbons is appropriate, the heat generated by combustion will keep the three-way catalytic converter in the best work In the temperature range, when the engine works abnormally, the content of carbon monoxide and hydrocarbons in the exhaust far exceeds the normal content, especially when the car is used for a long time, the medium and low-grade lubricating oil and the poor quality fuel contain sulfur, There are many harmful impurities such as carbon and phosphorus, or when the car is often idling or running slowly due to road congestion, sometimes the driving conditions are poor, the ignition time of the engine is too late due to a fault, or some cylinders misfire and do not work, or the fuel injection is normal but difficult to start, Phenomena such as too thick mixture, engine oil burning, etc. will cause colloidal carbon deposits and carbonization in the car engine intake, exhaust, and fuel system. It is easy to block the three-way catalytic converter of the car or even scrap it. After the blockage, it will not only increase the fuel consumption of the car, reduce the power, and the exhaust gas will exceed the standard, and even cause the car to fail to start.

[0003] In order to solve the above problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general products do not have an appropriate ratio to solve the above problems. Urgent problem
