Gasoline, when burned, produces harmful gases such as carbon monoxide, HC and NOx, which are also one of the "original culprits" of global warming. Therefore, there is a three-way catalytic converter in the exhaust pipe of the rear of the car, which can redox these harmful gases and convert harmful gases such as carbon monoxide, HC and NOx into harmless carbon dioxide, water and nitrogen.
The three-way catalytic converter is a very important part of the car, which contains rare metals such as platinum, rhodium and palladium, and platinum and silver can be obtained after refining. Therefore, the price of the three-way catalytic converter is not cheap, and it takes at least 3,000 yuan to replace a three-way catalytic converter. After hearing about it, some members of the "0 yuan purchase" in the United States also regarded it as a way to get rich, and even disassembled the catalytic converter on other people's cars on the street.
Recently, there is a video on the Internet that has attracted a lot of people's attention, it was late at night, there was no car on the road and no one, a small black car suddenly stopped on the side of the road, saw no one around, and two young men came down from the car. They looked around, saw no one, and began to work on the white Honda Accord parked on the side of the road.
A man took a jack from the car and lifted it up, and then the two took tools from the car, cooperated with each other, and quickly removed an exhaust pipe from the bottom of the car. Despite the piercing sirens of the white car, the two did not panic. After removing the exhaust pipe, the two men picked up the tools and left the scene.
Judging from the movements of these two men, they can be described as light and familiar, almost without any hesitation. And the speed of dismantling the exhaust pipe is very fast, so it seems that they should not be the first time to "live" pick the car catalytic converter.
Many car owners in the United States have encountered this kind of thing, and when they go home, they park their cars in the outdoor parking lot, and they find that there are many missing parts on the car on the second day. The parts they lost are worth recycling, and they can sell for a lot of money in the second-hand market. When purchasing used auto parts in the United States, some buyers find that parts such as catalytic converters are very sought-after, which may also be related to these "0 yuan purchase" members.
After they stole these parts, they also had many ways to deal with them, and they could use them to smelt metal, and the platinum and silver extracted were worth a lot of money. Even if they sell it to parts dealers, they have money to earn.
Although some states in the United States can not carry out annual inspections of automobiles, they will check the emissions of automobile exhaust, and if the exhaust emissions of automobiles are not up to standard, the car cannot be on the road. The catalytic converter is the most important part of the processing of automobile exhaust, and the catalytic converter on the vehicle is lost, and the exhaust gas is impossible to meet the standard.
The owner of the stolen car can be said to be the most pitiful, they want to repair the car, they can only spend a few thousand dollars to buy a three-way catalytic converter to install on the car. If you can't buy accessories, you have to wait for people to extract the metal from these stolen ternary catalysts, sell them to accessories manufacturers, and wait for them to make a ternary catalyst before buying. The whole process can be delayed by weeks, or even months.
According to the US police investigation, such cases have occurred many times, and they have also found many dens in the local area that harbor second-hand ternary catalysts, and some dens have at least thousands of ternary catalysts, which shows how many car owners have suffered.
The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system, without the three-way catalytic converter, the car is difficult to move. The owners of these lost three-way catalysts must be very upset, so everyone must look after their cars, and when they hear the car alarm, they must come out in time to check.
