Background technique

On December 5, 2011, foggy weather occurred in northern China, with visibility less than one kilometer, resulting in the closure of highways between several provinces and the delay or cancellation of more than 300 flights to Beijing. 201 1 December 4 at 19 pm, the monitored concentration of PM2. 5 in Beijing was 522, which is about 52 times higher than the World Health Organization's recommended PM2.5 air quality standard (10 μg/m3). The air pollution in the city is getting more and more serious. In the windless weather, the visibility of the air is only a few tens of meters, even more than ten meters. The polluted PM2. 5 pollutants are suffocating, and many residents in the city suffer from respiratory diseases, heart diseases and cerebrovascular diseases. Medical reports have long-term inhalation of PM2. 5 pollutants are carcinogenic. The World Health Organization also stated in the 2005 edition of the Air Quality Guidelines that when the average annual concentration of PM2.5 reaches 35 micrograms per cubic meter, the risk of death for humans increases by about 15% over the case of 10 micrograms per cubic meter. A report from the United Nations Environment Program said that the concentration of PM2.5 per cubic metre increased by 20 milligrams, and about 340,000 people in China and India died of PM2.5 contamination each year.

Traffic jams, vehicles stop and go slowly, the engine speed is low, the cylinder operating temperature is low, the gasoline is not fully burned, and a large amount of organic suspended PM2. 5 pollutants are generated; while the gasoline is not fully burned, it is easy to cause internal engine parts. Surface area carbon, engine carbon deposition makes oil and gas combustion less adequate, exacerbating the emission of PM2.5 pollutants, making urban air pollution more serious. The urban air monitoring report reported that the concentration of PM2. 5 in the traffic jam section was significantly higher than that in the non-blocking section, taking the example of PM2.5 produced in Beijing as an example. In the non-heating season, pollutants generated by motor vehicles and related industries account for more than 50% of PM2.5, and 46% of PM2. 5 pollutants are::, suspended solids with insufficient organic combustion. For example, the burning of cigarettes, the organic matter is not fully burned, it produces a large amount of organic suspended matter P0M, the indoor air pollution in the non-smoking restaurant is very serious, the average concentration of PM2.5 is 114 μg/m3, which is about the recommended PM2 by WHO. . 5 times the air quality standard (10 μg/m3). Automobiles produce PM2.5 organic suspended pollutants, oil problems, and engine problems, improve oil quality π| reduce PM2. About about 27% of suspended pollutants in suspended pollutants. The car is running slowly, the engine is running at a low speed, the engine cylinder is low in temperature, and the car engine is carbonized, so that the gasoline is not fully burned, which is the cause of the serious discharge of the organic pollutants in the car.

Car engine decarbonization, experienced drivers often introduce, feel that the car engine power can not go uphill, often turn off the fire when starting up, it is the valve carbon, it is better to go to the highway to let the car go high speed, the car engine runs at high speed When the working temperature is high, the carbon deposit on the machine parts will be partially burned off. In this way, the carbon removal has certain effects on the car engine. The problems are: increase the traffic volume of the expressway, waste energy and useless work, increase the environment. Carbon emissions. Another method is to add a carbon removal agent to the gasoline fuel. The role of the carbon removal agent is to increase the combustion temperature of the cylinder, which has an effect on carbon removal, but the problem is Some components of the engine are easily burned under the continuous high temperature generated by the carbon removal agent, reducing the working life of the engine. In this patent, a catalyst element is ion-implanted into the valve end face of an automobile engine, and the catalyst reduces the oxidative combustion temperature threshold of free carbon and organic matter that collides with the valve end face, so that free carbon and organic matter are fully burned, and the engine valve no longer accumulates carbon. Ensure that the car engine output power is stable.

In order to prevent carbon deposits in the gasoline engine and prolong the service life of the spark plug, some high-end cars use spark plug electrodes made of precious metals such as platinum, rhodium and palladium, which consume a large amount of precious metals. In order to reduce the cost of ordinary cars, noble metal electrodes are not used. After using a common metal electrode for a period of time, the carbon deposit will affect its ignition function. Even if the carbon deposit will short the electrode, the electrode will lose its ignition function. When this happens, the oil and gas mixture in the cylinder is not ignited by the spark plug, and the combustion works. It is discharged, and the concentration of combustible organic matter in the exhaust gas is increased. Even if the three-way catalyst is installed in the exhaust system of the automobile, the combustible gas cannot be completely catalyzed. Sometimes on the road, some car exhaust pipes are heard, that is, the engine is partially cylinder. The ignition of the spark plug fails, and the unburned oil and gas mixture passes through the exhaust pipe of the automobile and is catalyzed by the three-way catalyst. However, this deflagration situation is not fully burned and will produce a large amount of PM2.5 pollutants. If the car is difficult to start in the cool state, there is a clear sense of frustration, idling jitter, or engine acceleration performance, and the spark plug should be checked in time. Because of the above-mentioned performance of the vehicle, it may be caused by carbon deposits in the spark plug. At this time, the engine of the car is not working properly, the balance of operation is broken, the engine is violently shaken, and the engine output power is reduced. This phenomenon occurs when the spark plug must be replaced and the engine is removed for carbon maintenance. In this patent, the catalyst element is ion-implanted into the surface of the metal electrode of the automobile engine spark plug to reduce the amount of precious metal used, and has the same long service life and use effect as the noble metal electrode, which can prevent carbon deposit of the spark plug and make the engine work stably and reliably.

In the development of modern industry, there is a direct injection supercharged engine. The injector of the direct injection engine is installed in the cylinder of the engine. When the injector is injected, the gasoline changes from liquid to gas, and the phase of the object changes. The liquid is converted into a gaseous state to absorb heat. The injector is installed on the cylinder wall of the engine, and there is cooling at any time. The temperature of the injector is low, so that the oil and gas mixture will condense when it is collected on the injector. When the cylinder works, the oil and gas mixture burns. The oil mist and free carbon on the fuel injector do not reach the reaction threshold for the oxidation reaction with oxygen due to the low temperature, so that the combustion cannot be oxidized, so that the injector is easy to deposit carbon. The carbon deposit of the injector reaches a certain level. The oil passage will affect the atomization effect of the fuel injection. The gasoline cannot be fully mixed with the air. Therefore, the gasoline is not fully burned, the engine power is reduced, and the PM2.5 emissions are increased. In the patent, the catalyst element is ion-implanted into the nozzle end surface of the automobile engine and the injector nozzle, and the catalyst reduces the oxidative combustion temperature threshold of free carbon and organic matter that collides with the end face of the injector, so that the free carbon and the combustible organic matter are fully oxidized and burned. The engine injectors no longer deposit carbon. Greatly reduce PM2. 5 combustible pollutants and carbon emissions.

According to data at the end of 2011, China's car ownership is at least 168 million, and it is increasing at an annual rate of about 18 million. China is the world's largest car producer and the largest car seller. The number of cars in Beijing exceeded 4.7 million, which was limited to 250,000 due to the increase in the number of years. Even if some cities adopt car purchase restrictions, just 5 - 6 In the years to come, China’s cars will double. If measures are not taken to reduce the emission of PM2.5 organic pollutants from automobiles. At that time, what is the quality of air in China? People can also 1: "Do you have a life? People pay for air pollution PM2. 5 organic pollutants pay a lot of price? The total of the work | The immediate · #手治汽车发动机 produced in the PM2. 5 Organic pollutants. Improve the environmental performance of steam engines.

In the exhaust gas of gasoline engine, the cause of PM2.5 organic pollutants and soot particles: First, it is burning under anoxic conditions. This problem is developed by modern technology. The electrospray technology of gasoline engines can be commanded by the solenoid valve according to the ECU. To accurately control, not only that, the sensing component such as the oxygen sensor feeds back the exhaust situation to the ECU, so that the combustion condition can be judged according to the exhaust gas, and then the fuel supply amount can be further adjusted to achieve macroscopic rich oxygen-containing combustion; Under the condition, however, since the engine cylinder wall and the piston are always in the circulating cooling state, the engine is in cold start when running coldly or at a low speed, the engine oil is injected, the oil and gas mixture hits the low temperature valve, the spark plug, the nozzle surface, the valve, the spark plug The surface temperature of the injector is lower than the ignition point of the gasoline and free carbon particles, that is, lower than the oxidation reaction threshold of the carbon particles. The starting point of the carbon particles is: 550 degrees Celsius, at this time, adhered to the valve, the spark plug, and the surface of the injector. Carbon particles and organic matter cannot be surrounded by oxygen, oxidative combustion, when Motivation into the exhaust stroke, combustion air mixture not fully, i.e., a large number of PM2. 5 suspension of organic pollutants are discharged. This situation is especially noticeable when the car jamming engine is running at low speed and the engine is cold.

The carbon particle and organic catalytic combustion device of the automobile engine before the invention are all placed in the exhaust pipe of the engine without exception, since the thermal oxidation temperature of the soot particles is as high as 550 to 600 Ό, and the exhaust temperature of the gasoline engine is 175 to 400 °. C. A three-way catalyst for a gasoline engine catalyzes oxidative combustion of a combustible gas. At this time, the thermal energy of oxidative combustion is not used for mechanical work, but causes thermal pollution to the environment and causes urban thermal effects, which is particularly evident in summer. The increase in ambient temperature has the consequence of premature air conditioning in urban buildings, which in turn increases overall energy consumption in the region. The invention adopts the catalytic combustion method in the combustion chamber of the automobile engine, so that the PM2.5 organic matter and the carbon particles are completely burned in the combustion chamber of the engine, and the energy generated by the combustion of the PM2.5 organic matter and the carbon particles is all used for mechanical work, therefore, the technology extracts gasoline. The combustion efficiency of the engine, when the fuel quantity is the same, the output power of the gasoline engine is increased; when the car jam engine is running at a low speed, the engine does not deposit carbon, which greatly reduces the emission of PM2.5 organic pollutants. Oil and gas combustibles in automobile engines are fully burned to reduce the amount of gasoline used, save energy and reduce carbon emissions. More complete combustion of gasoline, full combustion of free carbon in the engine, reduce carbon deposits in engine parts, reduce mechanical wear, reduce lubricant contamination, extend lubricant life; reduce engine intake and exhaust carbon deposits, prevent engine Air leakage, maintaining engine output, does not decrease with extended use time, thereby extending the life of the gasoline engine and reducing maintenance costs. Summary of the invention

The gasoline engine valve, the fuel injector and the spark plug prevent the carbon deposition ion treatment method. The method 1 is: using the MEVVA source ion implanter to inject the catalyst ions into the valve surface, the fuel injector and the spark plug metal electrode surface; The oxidation threshold of carbon particles and organic matter that collides with the valve, the injector and the surface of the spark plug is reduced by the catalyst, which promotes the catalytic combustion of carbon particles and organic matter, thereby reducing the carbon content of the valve, the injector and the spark plug surface; Air leakage, engine output power loss; fuel injector carbon deposit, block oil circuit, affect gasoline spray effect; spark plug carbon ignition circuit produces short circuit, so that the engine power stroke can not be normally ignited, oil and gas mixture is not fully burned, that is, a large amount of PM2 5 Organic pollutants, which cause the engine to run unbalanced to generate vibration, and the output power is reduced. The invention can avoid the engine from carbon deposit due to spark plug, ignition failure, resulting in lower output power and environmental pollution, improving combustion efficiency and reducing carbon emissions; During cold start and low speed operation, due to the low working temperature of the cylinder, the gasoline is not fully burned, the free carbon adheres to the surface of the part, the internal parts of the cylinder are easy to deposit carbon, and the PM2. 5 organic pollutants are not fully burned by the automobile. Air pollution is serious, often The catalyst reaction device of the gasoline engine before the invention is placed outside the cylinder of the engine, and the heat energy generated by the catalytic combustion of carbon particles and organic combustibles in the cylinder exhaust system cannot contribute to the work of the gasoline engine, and the heat energy is discharged. In the environment, environmental thermal pollution is generated; the invention adopts a composite ion implantation method, injecting a solid catalyst into an element to form a cathode shape (generally using one of the most required injection elements), and injecting one or more other elements into the environment. It is made into a thin column shape.

The oxygen atom provides oxidation of the carbon particles, and in the oxygen-rich atmosphere, promotes sufficient oxidation and combustion of the carbon element. Therefore, the engine carbon deposition is eliminated, and the emission of carbon particles and the emission of organic pollutants of PM2.5 are greatly reduced.
