Will the unqualified tail gas be captured? That's right! "Tail gas remote sensing monitoring" is online!

A while ago, a choreographer of our team (the director of The Measurement of Tao and Tiger) mentioned something to me. A while ago, he and his buddies drove to Chongming Island in Shanghai for an outing. The two brothers each drive a car and drive in teams on the same road.

Suddenly, a huge electronic screen appeared in front, and a line jumped out of it-Shanghai AXXXXX's exhaust emission exceeded the standard! Warning once! ..... At that time, you were puzzled: I was driving well on the road, how could the exhaust emissions exceed the standard? How does this electronic big screen know that my car's exhaust is not up to standard?

So you people, believing in evil, want to try again to see who this big screen is, so you turn around and drive back ... Finally, when the car approaches the big screen, it is displayed on the screen again ... Shanghai AXXXXX's exhaust emission exceeds the standard! Warning once! ..... it's amazing!

Exhaust gas was detected as soon as the car passed by?

Finally, everyone knew when asked: this is the only car in the team, modified with engine exhaust! Replace the three-way catalytic converter with a modified version of the "metal high flow" kit, and then dismantle the particle trap (GPF), and brush the program to fool the computer and sensor ... The engine power has increased, the performance has been optimized, and of course the exhaust gas is not up to standard.

However, there is still a problem that everyone can't explain: how do you know that the automobile exhaust is not up to standard with a big screen on the road? And at that time, their team kept the speed of 60~80KM/H all the way, that is, it passed the big screen with a whoosh. I didn't see anyone or any equipment sticking out to detect waste gas. ...

Remote sensing detection system for automobile exhaust

Get to know it?

This matter came to me, and I finally found the answer: this so-called big screen is actually called the real scientific name-automobile exhaust remote sensing detection system. In fact, the principle of this product is really not complicated. In this system, it includes: exhaust gas analysis system, vehicle speed detection system and camera system.

The exhaust gas analysis system works according to the infrared/ultraviolet principle: it emits infrared and ultraviolet rays on the road surface. Special reflectors and optical detectors are installed at the other end of the road. When vehicles pass by, the tail gas will be discharged into the atmosphere, which will interfere with infrared rays and ultraviolet rays. Infrared ray is used to detect CO2, CO and HC, and ultraviolet ray is used to detect the emission of nitrogen oxides.

The vehicle speed detection system is basically a laser velocimetry radar, which can be used to detect vehicle speed and vehicle acceleration and deceleration. The camera system is used to shoot license plate information. -When a car passes by, it will be photographed by the system. Then the speedometer measures the vehicle speed, and then the infrared/ultraviolet system instantly detects the exhaust gas. ...

Being photographed on the road, if you pretend not to see it.

What are the consequences?

In this way, as long as there is something wrong with your car exhaust, it will be captured instantly by this system, and then … your license plate number will appear on the big screen! Then the problem comes: if you encounter this situation, you will ignore it. What will happen?

It's very simple: when the electronic big screen shows that your car's exhaust gas is unqualified, the traffic police department will contact you (send a text message, of course, it will be more convenient if there is an "Traffic Management12123" app) to tell you how long it will take to check the exhaust gas at the corresponding car inspection office. Then you must finish it within the specified time. Otherwise -200 yuan fine +3 points is no joke.

Then you may ask: How accurate is this system? After the inquiry of the technical department, we got the following answer: If the car of 1 is caught by the remote sensing detection system of automobile exhaust twice in a row, it basically means that there is something wrong with your car exhaust! Yes, the accuracy is so exaggerated! This system can be summarized in three words: awesome!

In the future, tail gas control will only become more and more strict.

This may not be "friendly" to old cars.

At present, this kind of high-tech equipment is rarely encountered in third-and fourth-tier cities and subordinate counties. However, in super-first-tier, first-and second-tier cities, provincial capitals and other places, there are more and more remote sensing detection systems for automobile exhaust, and the number of traffic police departments is also increasing ... ...

In the past, we might be able to ask some "yellow cattle" for help in the annual inspection of automobiles, but now the remote sensing detection system of automobile exhaust is fully automatic and computerized. And once the snapshot is uploaded directly to the system, the "yellow cattle" can't help. Students with improved exhaust gas may really worry about their cars. ...

Some modified players don't think the rules are getting wider and wider. After all, the banner of environmental protection was set up several years ago. I think everyone knows that the supervision of motor vehicle exhaust will definitely become more and more strict. In 2025, maybe the "Seventh National Congress" will really land. At that time, the exhaust gas supervision will be even more abnormal ... Alas ... maybe only "zero-emission" trams can survive!
