Kan Chejun's last article "Car Smell | Bet on "3.15", I admit that there is an ingredient in the bet", for the volkswagen to explore the particle trap caused by the problem of excessive fuel, did not expect to be fiercely criticized by the platform public fans. Let's talk about the little particle traps and the things that are probing.
(Particle Trap)
What does a particle trap do?
Maybe many old-school drivers don't know much about what a particle trap is, and what is adding this part to make the vehicle run more smoothly? Or is it to make the ride more comfortable? Why have I never heard of it before? So let's start with the principle of particle traps. ‘
The Particle Trap DPF (Diesel Particulate Filter) is a filter installed in the emission system of the gasoline internal combustion engine that captures particulate emissions before they enter the atmosphere. In layman's terms, it is to add a mask to the engine to make the air it swallows cleaner, because this layer of mask has a filtering effect, can effectively collect particulate matter, and burn it through high temperature. From the literal interpretation, it can be clearly seen that it has nothing to do with the consumer's car experience. So why add such an accessory that resembles a rotten tail? This has to start from the national policies and regulations.
As a responsible major country in the process of globalization, China is extremely strict about tailpipe emissions. The three-way catalyst can help many engines to solve the problem of exhaust emissions, but the national six b is known as the most stringent in history, and many enterprises can not meet this standard with heavy investment in the research and development of the engine, so they add a layer of masks behind the three yuan, which is now the particle trap. After such a big circle, everyone should also understand that the product emission standard is what the manufacturer should do, and the particle trapper should be regarded as a patch for the manufacturer's product quality not meeting the standard.
(A large number of passenger cars are equipped with particle traps)
Of course, Kan Chejun is not a virgin, and it has become the mainstream practice of the industry to carry particle traps, and many consumers have turned a blind eye. The problem is, consumers allow you to add patches, but this patch can't always affect the car experience, right? And Tanyue is because the patch of the particle trap is unqualified, resulting in a model of product quality defects.
There are two types of particle traps – Tanyue, and the others
As mentioned above, particle traps can solve pollutant emissions from the national level, and can meet the national VI b emission standards from the sales level. The starting point of this design is good. But when too many carbon particles in the particle trap begin to congest, it is necessary to maintain the engine at a high speed to eliminate the blockage and enter the GPF regeneration stage. The cost is increased fuel consumption.
So far, there have been more than a hundred brand models equipped with particle traps, and this problem of rising fuel consumption occurs from time to time. But never before has a brand, a model, been so concentrated in the outbreak of particles that have led to a collective increase in fuel consumption due to the particles. This model is the Volkswagen Tangaku.
As of press time, on the list of quality complaints, Tanyue's various problems are still high. The large number of reporting problems related to the blockage of FAW-Everyone's Tanyue particle trap has already occurred since February 2021, and gradually broke out in large numbers in March and April, and is still soaring so far. Among them, more than 95% of the reported cars are the 2020 330TSI two-wheel drive luxury intelligent network version and 330TSI two-wheel drive luxury intelligent networking version PRO. In addition, there are also a small amount of 280TSI two-wheel drive luxury intelligent network version of the car series, owners have encountered various problems caused by the particle trap level one to six blockage, including fuel consumption surge, driving force reduction, frequent invalid start and stop, engine abnormal sound and so on.
These include problems such as high fuel, transmission setbacks, and failed start-stop functions. In fact, these problems are caused by the blockage of particle traps, and many owners who have problems say that the use of low ash oil and the addition of high-quality fuel during maintenance can largely avoid this situation. But after driving again for a while, the problem will happen again, and people can't help it.
No wonder some people say that there are two kinds of particle traps in this world, one is called Tanyue, and the other is called other.
The person who asked the question if it can't solve it?
Since the particle trap has been widely adopted, but various problems have been concentrated on the tanyue, many tanyue owners speculate that the design of the particle trapper regeneration countermeasures of the tanyue is flawed, resulting in more easy clogging than other models. They expressed the hope that the main engine factory and dealers will recall and replace as soon as possible, and deal with the problem of plugging the Tanyue particle trap as soon as possible. So how did the volkswagen official feedback?
FAW-Volkswagen customer service and auto 4S shop after-sales service current solutions to problem owners are mainly two points: one is software upgrades, the other is to increase heat insulation protection, and suggestions are also given for car owners for daily use: running fast and running for thirty minutes or in situ regeneration. Hearing this suggestion, a little bit of car common sense will feel incredible, to know that the rapid sliding during the driving is very dangerous, serious violations of traffic laws, and in situ regeneration of high speed 3000 rpm for thirty minutes is very hurtful.
After this proposal was widely complained about, the official has now changed the statement, calling on the owner to add No. 98 gasoline. And because when the speed of the car exceeds 100 kilometers per hour, the exhaust pipe temperature exceeds 700 ° C, the combustion conditions can be achieved. This kind of practice of not thinking of improving their own product solutions but increasing the cost of user use is simply a problem that is not solved, and the person who solves the problem is solved!
Although some problems in the car are inevitable, as long as the manufacturer handles it properly, consumers are completely understandable. As the main model of the largest overseas automobile brand in China, because the particle flutterer plugs small things, blindly throwing the pot, pushing and unloading, covering up, will only make the problem more obvious, so that FAW-Volkswagen can be described as a brand style lost, the so-called thousand-mile destroyed in the ant nest, the fundamental problem of product quality is not attached to, is it not enough to attract the attention of the public?
