When it comes to the problem of particle trap blockage, everyone will first think of Volkswagen, for a long time, Tanyue and Tiguan two models were firmly at the top of the complaint list, consumers are complaining, now, feng shui turns, Toyota has also suffered large-scale complaints due to the same problem, and more models are involved than Volkswagen.
Just picked up the car for a month, add are regular gas station oil, every time before driving the car is warmed up, also run through the high-speed, now only opened 1400 kilometers on the prompt blockage, 4S shop replied to let run high-speed, there is no ** way, before buying a car sales recommendation is to run in the city to run more fuel-efficient, now there is a problem to tell me that the main thing is to run in the city to run the slow problem, nothing to run more high-speed, I bought a car is mainly to save fuel in the urban commuting, now let me run more high-speed, who will compensate for the time and fuel costs!”
After driving 1729 kilometers, there was a blockage fault of the particle trap, and the high-speed was pulled according to the 4S shop, which did not work. We don't buy a car back and forth on the highway, run long distances, and it turns out that the vehicle has serious quality problems. ”
After the first maintenance, the engine prompts that the exhaust filter is blocked, and it is recommended to warm up the engine!The 4S shop recommends running at high speed and stepping on the accelerator!I have tried it to no avail, and now it continues to increase the probability of blockage, and now the fuel consumption is obviously higher, the engine power is reduced, and the fault code is frequently reported. ”·
A few days ago, on many complaint platforms, the editors of "Automobile Professional Network" noticed that many Toyota owners complained about the blockage of particle traps, involving a variety of its models, including Corolla, Corolla Ruifang, Fenglanda, Leiling, etc., that is to say, whether it is FAW Toyota or GAC Toyota, there are models with "particle trap blockage".
If you observe further, there are two commonalities in the models of the Toyota brand that broke out "particle trap blockage" this time, that is, they are both Shuangqing models and 2023 models, but they are the old Shuangqing models under the Toyota brand, and none of them have been complained about, why is this?Some car owners revealed that it is said that the GPF installation position is too far back and cannot be effectively heated.
Traceability "particle trap", which is a new type of device that appeared in response to the China VIB emission standard, can effectively reduce the particulate matter emitted by automobiles and protect the environment and human health. However, particle traps can also have an impact on a vehicle's power, fuel consumption and maintenance costs.
Wan Chunlei, an automotive technology expert, believes that the most fundamental reason for the blockage of particle traps is technology and cost. "At the technical level, there are many factors that cause particle trap failure alarms, including engine technology, particle trap installation location, oil usage, etc. ”
In terms of engine technology, it is affected by factors such as fuel injection mode, fuel injection pressure, cylinder pressure, compression ratio, etc., which will directly affect whether the fuel is fully burned in the cylinder. A relatively large amount of particulate matter will gradually accumulate in the GPF microporous cavity through the exhaust manifold, increasing the risk of clogging.
The location of the particle trap is also one of the larger factors. If the installation position is relatively forward, the waste particles can be burned twice through the temperature generated by the engine, so as to achieve the purpose of self-cleaning. If it is like the Corolla model, the position of the particle trap is in the middle and tail section of the exhaust pipe, which is greatly affected by the temperature, and the harmful particles in the particle trap cannot complete self-cleaning, and will be blocked after a long time.
Wan Chunlei added that as far as the complained models are concerned, they are all HEV hybrid models, which are the drive mode of engine + electric motor, and when driving in short-distance or relatively congested urban roads, there are more working conditions of medium and low-speed electric drive, resulting in the engine being in a semi-hot or even cold state for a long time. Therefore, the particle trap has been in this working state for a long time and cannot reach the working temperature required for self-cleaning, which will lead to the blockage of the particle trap, especially in the north, especially in the northeast, and the vehicle problem is more serious.
