How many times of failing the exhaust emission test will lead to mandatory scrapping?
2 Answers
If a vehicle fails the exhaust emission test three times, it will be mandatorily scrapped. Below are the management and hazards of vehicle exhaust emissions: Management of vehicle exhaust emissions: This should be approached from two aspects. First, control technology, mainly improving fuel combustion efficiency, installing pollution prevention treatment equipment, and developing new types of engines. Second, administrative measures, such as scrapping and renewing vehicles, phasing out old cars, developing new types of vehicles (i.e., motor vehicles with no pollutant emissions), and controlling fuel usage standards. Hazards of vehicle exhaust emissions: While directly harming human health, exhaust emissions also have profound impacts on the environment we live in. Sulfur dioxide in exhaust has a strong irritating odor and, when reaching certain concentrations, can easily lead to "acid rain," causing soil and water sources to acidify and affecting the growth of crops and forests.
I've been driving for nearly twenty years and have gone through many tailpipe emission tests. It's common to fail the first time, but usually, some repairs like cleaning the catalytic converter or replacing spark plugs will get you through. However, if you fail three times in a row, the car is directly scrapped. This standard is generally cumulative within three years, based on the "Motor Vehicle Safety Technical Inspection Regulations." After scrapping, you have to deregister the vehicle, and buying a new car becomes more troublesome and costly. My advice is to maintain the car regularly, check the oxygen sensor and intake tract, and don't wait until the third failure—otherwise, scrapping is inevitable, affecting daily travel. Remember, if you fail in the first two years, take it seriously—don't let minor issues turn into major problems.
