Recently, volkswagen is quite upset, although a large number of soft text has been put on major websites, but it is still difficult to cover up the problem of the particle trap blockage of the Volkswagen's Tiguan L and Tanyue, many car owners said that the fuel consumption of their car soared to 30 liters, and the solution given by the 4S store is to run more high speed and add 98 gasoline, the Volkswagen particle trap blockage problem, but also gave birth to a new occupation, that is, running high speed, but also the public to solve the employment problem brought positively.
For the particle trap blockage, many people are puzzled that so many cars have been equipped with particle traps, including many domestic cars, it is reasonable to say that Volkswagen's technical strength is very strong, at least much stronger than many domestic cars, right? Why is there a large-scale congestion problem in only Volkswagen models?
Self-priming models often do not require a particle trap
In fact, in order to cope with the National VI B emission standards, the vast majority of turbocharged engines on the market at present, are using particle traps, including German, Japanese, American and autonomous, etc., so the particle trap is definitely not Volkswagen so do, the reason is that the standard of China VI B is too high, and it is almost difficult for each car company to meet this emission standard, and can only be opportunistic and install masks for its models.
However, many self-priming engines do not require particle traps (not absolutely, some self-priming engines also use particle traps), and these engines do not require GPF to meet the requirements of China VIB. Volkswagen's models mainly use turbocharged engines, and Volkswagen has no time and no technology to solve emission problems at present, so the use of particle traps has become a helpless move. There are rumors that Volkswagen's fourth-generation EA888 will meet the standards of China VI B from the design level, and does not require a particle trap.
Design problems with models such as Volkswagen Tangaku
So since many turbocharged engines are equipped with particle traps, why jam the public? The reason is very simple, that is, the design is defective, the particle trap this thing, in fact, the working temperature is closely related, in simple terms, the closer to the engine, the better the combustion effect, the more full the regeneration, but the public has no experience, put the particle trap behind the silencer, which leads to a problem that the temperature is not enough, many particles can not regenerate, that is not blocked?
On the other hand, in fact, the technical accumulation of German car companies in the field of engines has also approached the bottleneck, their strongest technology is in the diesel engine, and in the case of electrification transformation, Audi announced that it will stop the development of fuel engines in 2025.
Even the traditional large factory Volkswagen, in the face of more and more stringent emission standards are helpless, it is foreseeable that in the future, more and more car companies will step up the transformation of electrification, such as the use of Atkinson cycle engines, it as a generator to drive vehicles, more use of motors, etc., the era of pure internal combustion engine is indeed coming to an end, the future hybrid models and electric vehicles, will become the mainstream of the automotive market.
