The "Three Guarantees for Cars", which made people wait for a long time but had never had a hard time, had a "fetal movement" on the last day of 2012. On the same day, the AQSIQ National Standardization Management Committee asked the community for opinions on the scope of the main parts and the three packs warranty (Exposure Draft) of the “Three-Packs of Household Vehicles Products†(hereinafter referred to as the “Draft for Soliciting Opinionsâ€) and solicited opinions in 2013. Feedback will be given before January 31st of the year. As one of the important members of the SCR system, the Nox sensor consists of a sensor probe and an electronic control unit. They are connected by wire harnesses and are used to measure the concentration of nitrogen oxides and oxygen in the exhaust gas. In practical applications, the probe is installed in the automobile exhaust pipe, and the exhaust gas concentration is fed back to the electronic control unit in the form of voltage through the ceramic chip. The heating temperature of the sensor probe is controlled by electronic control and through a series of signal conditioning, the concentration of Nox and oxygen in the pump is finally determined. The electronic control unit communicates with the vehicle control center (ECU) through CAN, and transmits the measured gas value to the vehicle control center (EUC) in real time, providing a basis for the SCR injection amount, thereby reducing NOx emissions.

This matter is not interpreted by the authority of the industry. People also all know that the introduction of the “Draft for Soliciting Opinions†means that the “three guarantees†policy that has been pending for a long time has already been put on the agenda. It is not far from the final announcement. For consumers, this can be considered a good New Year gift, although the gift is still virtual, after all, there has been a bit of hope.
To be fair, some of the explicit contents of the Exposure Draft are still very exciting. For example, "automobile products from the seller within 60 days from the date of purchase of the invoice or within 3000 kilometers, whichever occurs first, and the main parts of the engine and transmission have quality problems, consumers can choose to replace the engine for free, In the three-pack validity period, after the engine or transmission is replaced twice in total, or the same main parts of the engine and transmission are not replaced after two cumulative replacements due to quality problems (the assembly and replacement of major parts) If the consumer chooses to replace or return, the seller shall be responsible for replacement or return."
For another example, "In the period of validity of automotive products, the same main parts of the steering system, brake system, suspension system, front/rear axle, and vehicle body cannot be used normally after two cumulative replacements due to quality problems. If the seller chooses to replace or return the product, the seller shall be responsible for the replacement or return of the product; and if the consumable parts of the household automotive product have quality problems during the quality assurance period, the consumer may also choose to replace the easily-worn component for free.
As the industry analysts have analyzed, these regulations are operable and more reasonable for consumers. If they are approved for implementation, consumer rights can be better protected, and they can also promote the development of the automotive industry. .
However, people still have to worry about it. All along, the game between consumers and manufacturers is in a weak position, and the identification of product quality issues is still difficult. Shen Jinjun, executive vice president of the China Automobile Dealers Association, believes that the possibility of the introduction of the "car three packs" policy in 2013 is very high. However, the most important thing depends on how the policy is implemented. At present, the number of third party accreditation bodies is relatively small. At the same time, consumption How to identify and obtain evidence in the process of maintaining the quality of automobiles is still a difficult problem.
However, there are also some expert-level people who put forward the opposite opinion. They think that whether they have quality problems are originally technical matters. In addition to distinguishing the responsibility, the quality inspection department should entrust professional technical units or individuals to do the identification. I'm worried about appraisal issues or worry about people.
Is this worry really worrying people? Perhaps, there are some such ingredients, but people's concerns are not entirely unreasonable. Everyone knows that there are tens of thousands of parts in a car, among which there are five or six hundred kinds of wearing parts. No matter which part has a problem, it is caused by improper use of the car owner, or the quality of the car itself. What kind of problem is in line with the change of car? The standard, the standard of returning cars, and the cost of expensive identification should be borne by everyone. Many problems require a clear statement beforehand to ensure the implementation and implementation of the Three Guarantees policy, so as to truly protect the interests of consumers. And in the absence of a clear answer to the above questions, how can people's fears be simply treated as "deaf people?"
In addition, after the introduction and implementation of the future Three Guarantees policy, the quality appraisal of automotive products will be normalized. Of course, we are more willing to believe that appraisers can become fair and unselfish "black-faced Baogong", but if consumers are concerned about the quality of products at that time. There is no talk with the manufacturer. The delegated professional and technical unit or individual speaks for whom, and whether the appraiser's qualification is sufficient to convince the public is now unknown. With the facts still uncertain, do people worry that it will not be possible?
Obviously, the phrase “deaf people worry about heaven and earth†is to impose a label of ignorance on consumers who are worried. This kind of hard-headed gesture that speaks loud and hard on language rights is itself unfair, and this will only make people worry. Deepened. It is precisely because of this that we hope that when officially launching the “Three Guarantees†policy, the government can effectively solve these problems at the system design level, eliminate people’s concerns, and make it truly play a fair role in safeguarding the interests of both consumers and factories. The "accelerator" in the real sense of the development of the automotive industry and the automotive market.
