The three-way catalytic converter is the most important off-board purification device installed in the exhaust system of automobiles. It can convert harmful gases such as carbon monoxide, hydrocarbons and nitrogen oxides emitted from automobile exhaust into harmless by oxidation and reduction. Carbon dioxide, water and nitrogen. Since this catalyst can simultaneously convert three main harmful substances in the exhaust gas into harmless substances, it is called ternary.
The three-way catalytic converter cleaning agent is made of non-chlorinated benzene-based environmentally friendly solvent, which can effectively clean impurities, carbon deposits and other deposits in the three-way catalytic converter of the automobile; prevent "catalyst poisoning" caused by heavy metal adhesion. The occurrence of harmful substances in the exhaust gas can also be removed to the inlet, valve, combustion chamber and sediments at the same time to improve the efficiency of the engine. After cleaning, the energy saving and consumption are obvious, and the exhaust emission standard is improved.
1. If the exhaust pipe is boring and the exhaust is not smooth, it is likely that the three-way catalytic converter is blocked.
2. After cleaning the throttle valve and the fuel injector, the vehicle still has insufficient power and increased fuel consumption. It may also be caused by the three-way catalytic converter.
3. When the cold car starts, it often smells very smelly, and it is also mixed with gasoline smell, which is mostly because the three-way catalytic converter has failed.
If any of the above occurs, it is likely that it is caused by a problem with the ternary. It is necessary to ask the maintenance master to check the cause as soon as possible to determine the cause. Although many car maintenance shops have ternary cleaning agents, which is the kind of hanging bottles, but the effect of cleaning is really not flattering, to a large extent only to give the car owners a psychological comfort. The most effective method is to remove the cleaning, but it is too cumbersome and the working hours are high. Therefore, it is still necessary to maintain the three-way catalytic converter in peacetime.
Three-way catalytic converter maintenance1. Do not use inferior gasoline. When gasoline contains more lead or other impurities, some impurities remain after combustion, and some of them are discharged into the three-way catalytic converter along the exhaust pipe. In the long run, the ternary is blocked. And this is the main reason for the ternary blockage.
2. Try to ensure that the engine works normally and the air-fuel ratio is at its best. If the fuel is not fully burned, carbon deposits are inevitably formed, which not only increases the working strength of the ternary, but also easily forms carbon deposits on the ternary, causing it to clog.
3. After cleaning the throttle and injector, it is recommended to clean the ternary again. This is because the carbon removed during the cleaning of the throttle and the injector enters the three-way catalyst with the exhaust pipe. When the carbon deposit is more serious, it will block the ternary.
After the ternary cleaning agent enters the combustion chamber through the intake vacuum tube, a high-temperature oxidation environment is established around the ternary purifier, and the sulfur and phosphorus chemical complexes attached to the surface of the three-way catalyst are oxidized and reduced, and the gasoline is incompletely burned. The product is discharged into sulfur dioxide and carbon dioxide gas, thereby achieving the purpose of cleaning the ternary and restoring the activity of the three-way catalyst. The ternary cleaning agent can be fully burned in the combustion chamber, so there is no harm to the engine.
The detached three-way catalyst is erected in a container (plastic barrel), and a bottle of three-way catalytic cleaning agent is evenly poured into a kettle of the high-pressure spray gun, and the gas pipe is connected to the inner grid of the three-way catalytic converter. Uniform injection, the three-way catalytic converter can be repeatedly adjusted to clean the head (preferably after 6 seconds of spraying for 3 minutes). The syrup will uniformly penetrate into the deep layer of carbon deposit, rapidly foaming, dissolving carbon deposit and turning into mud. At the same time, the slow release agent in the syrup forms a protective film on the metal surface, and effectively protects the ruthenium, platinum, and palladium precious metals sprayed on the grid substrate.
After the cleaning agent is finished, open the spray gun pot and fill it with water for more than three bottles. It is best to wash the grille against the grille with a high-pressure spray gun to ensure that the mud between the gaps between the three-element grille can completely flow out. Rinse directly with a water pipe and blow dry with high-pressure gas. After installing the three-way catalytic converter, please check if it leaks, and check whether the intake, ignition and fuel supply systems of the engine meet the requirements. If there is a problem, it should be repaired as appropriate.
After the road test 3 to 20 kilometers to activate the catalytic converter of the three-way catalytic converter, the computer ECU also completed the self-learning. At this time, the power and acceleration performance of the automobile are obviously improved, and the exhaust gas detector can be used to detect various indicators, and the fault is completely eliminated. exclude.
The so-called mini projector is also called pico projector, TRT-Lcos Portable Projector. Mainly through the 3M LCOS RGB three-color projector and 720P film decoding technology, the traditional huge projector is refined, portable, miniaturized, entertaining and practical, making the projection technology closer to life and entertainment.
Usually the projector has certain regulations on 2 aspects:
a). Size: Usually the size is the size of a mobile phone.
b). Battery life: It is required to have at least 1-2 hours or more of battery life when it is not connected to power.
In addition, its general weight will not exceed 0.2Kg, and some do not even need fan cooling or ultra-small silent fan cooling. It can be carried with you (it can be put into your pocket), and the screen can be projected to 40-50 inches or more.
Advantage:
1. Completely replace the MP5 player, video, listening to songs, playing games, e-books, picture browsing, etc. MP5 video is affected by physical performance, the screen can not be bigger, and the screen of this thing is at least 20 inches.
2. Instead of the TV function, the machine can have a built-in CMMB function, or it can be directly connected to the set-top box to play the TV, and it can be used as a 21-inch TV during the day.
Look, it can be used as a 60-100-inch TV at night to achieve the effect of home theater; it is convenient to move and break through the traditional film and television space. Even if you are on the mountain, you can also share today's TV series, movies, and MTV with your lover.
3. Business office: instead of large projectors, it is used for company meetings; the price of large projectors is 4,000 to 14,000, and the lamp life is more than 1,000 hours, which is not convenient to carry. 30,000 hours, no need to change the bulb for 3 years, easy to carry, the salesman only needs to bring a micro projector to demonstrate the new product, which can achieve the demonstration effect.
4. Teaching: training meetings, classroom teaching; traditional projectors are not easy to carry. In school classrooms, due to the naughty students, projectors are not safe to place in the classroom and are easily damaged by students. The portability of micro projectors makes up for the teaching vacancies. In the future, teachers only need to store the materials in the projector and show them to students for teaching, saving the trouble of textbooks and handwriting with pens and chalks.
In addition, the micro-projection has no radiation, which can fully protect pregnant women and people with myopia. Its low power consumption function is 1/1,000,000 of the power consumption of color TVs. One day of electricity has completely impacted the indicators of safety, environmental protection, health, etc., and has made amazing contributions to future social development, standing at the peak of the green world as a leader.
