Abstract
The present invention discloses a cleaning and maintenance method for a three-component catalyst of a gasoline car, which aims at providing a convenient, simple, safe and reliable method which can NO content in discharged tail gas and can also improve the application environment of a three-component catalyst so as to ensure the normal application of the three-component catalyst and prolong the service life. The present invention is realized by the following method: a fluid transfer device is used for inputting three-component cleaning agent into a combustion chamber of an engine from a rubber air inlet vacuum pipe of the engine, and the three-component cleaning agent is combusted in the engine to generate oxygen ions, the oxygen ions is chemically reacted with sulfur, phosphorus chemical complex and products which is not completely combusted in the three-component catalyst to form gas to discharge.
Description
Technical field
The present invention relates to a kind of method for cleaning and maintaining of automotive field product, particularly a kind of ternary catalyzing unit of gasoline motorcar cleans the method for maintenance.
Background technology
Current social, the industrial production fast development, ecological environment is seriously damaged, air pollution is serious, and particularly living standards of the people improve, and private car enters in the common people family, and principal element of air-polluting is: automobile gives off a large amount of pernicious gases in using, though installed ternary catalyzing unit additional, sulfur-bearing, phosphorus composition height in the gasoline easily form one deck sulphur, phosphorus chemistry complex compound on the ternary catalyzing unit surface; The city blocks up, the gasoline car frequent starting, cause engine combustion insufficient, and the burn incompletely product can be attached to the surface of ternary catalyzing unit, cause the ternary catalyzing unit function to reduce, nitrogen oxide in the exhaust emissions (NO) content overproof has aggravated the pollution of air, simultaneously vehicle occurs also that exhaust is smooth, back pressure improves, and excessive fuel consumption in the use, phenomenon such as be short of power.
Summary of the invention
The present invention has overcome the deficiency in the existing ternary catalyzing unit use, provide a kind of both convenient, simple, safe and reliable again method can not only reduce the content of nitrogen oxide in the exhaust emissions (NO), also can improve the environment for use of ternary catalyzing unit, guarantee the normal use of ternary catalyzing unit.
For solving the problems of the technologies described above, the present invention realizes by the following method: be that 100% methyl alcohol joins in the engine chamber from engine rubber air inlet vacuum tube with percentage by weight, after described methyl alcohol burns in engine, produce oxonium ion, sulphur, phosphorus chemistry complex compound and imperfect combustion product generation chemical reaction in oxonium ion and the ternary catalyzing unit generate gas and discharge.
The adding method is to insert in the rubber air inlet vacuum tube by hollow pinhead among the described step a, and the adding percentage by weight is 100% methyl alcohol; Be connected to reservoir behind the described hollow pinhead; Described hollow pinhead and reservoir are medical Transfusion device.
By above technical scheme as can be known the present invention be that 100% methyl alcohol joins in the engine chamber from engine rubber air inlet vacuum tube by hollow pinhead with percentage by weight, after fully burning, produce oxonium ion, sulphur, phosphorus chemistry complex compound and imperfect combustion product generation chemical reaction in oxonium ion and the ternary catalyzing unit generate gas and discharge.Its beneficial effect is: the service life that 1, significantly improves ternary catalyzing unit; 2, fully reduce the content of nitrogen oxide in the exhaust emissions (NO), guarantee that exhaust emissions meets national standard; 3, reduce fuel consumption, improve mobility in the automobile use; 4, can fully burn, not have residue, safe in utilization, reliable; 5, convenient and simple for operation, with low cost.
The specific embodiment
Below specific implementation method of the present invention is further described: the transfusion device that percentage by weight will be housed be 100% methyl alcohol inserts in the engine rubber air inlet vacuum tube, the ato unit idle running, is that 100% methyl alcohol sucks by atmospheric pressure with percentage by weight, fully burning in engine, after cleaning process is finished, extract transfusion device.
The principle of described cleaning ternary catalyzing unit is: percentage by weight is after 100% methyl alcohol enters combustion chambers burn by air inlet pipe, produce a large amount of oxonium ions, around ternary catalyzing unit, set up a high-temperature oxidation environment, will be by redox reaction attached to sulphur, phosphorus chemistry complex compound, the incomplete product of gasoline combustion on ternary catalyzing unit surface, become sulfur dioxide, carbon dioxide discharge, thereby reach the purpose of cleaning ternary catalyzing unit, recovering the ternary catalyzing unit activity.
Described adding percentage by weight is the method for 100% methyl alcohol, also can directly insert in the air inlet vacuum tube loop by other equipment, adjusts valve, the input quantity of control methyl alcohol.
Influence the factor of described methyl alcohol result of use:
A. the inefficacy that causes because of metal poisoning and high temperature sintering of ternary catalyzing unit;
B. ternary catalyzing unit surpasses 200,000 kilometers service lifes;
C. ternary catalyzing unit sulphur, phosphorism are darker, and chemical complex covers thicker, and needing repeatedly to clean the back effect can be remarkable; Carburetor installs electric controlled gas-compensation three-element catalytic modified car and single-point EFI car additional, because of the excess air coefficient control accuracy is low, reduces exhaust emissions effect instability.
Embodiment 1:
