In November 2020, Mr. Lin purchased the Tanyue 2020 330PRO sedan at Ningde Yingzhong Automobile Co., Ltd., but his car's fuel consumption would suddenly increase from 7 or 8 liters directly to 14 liters, and the engine rustled. Mr. Lin went to the Ningde Yingzhong 4S shop to repair the car, and the staff told him that it was the exhaust gas collection device particle trap that blocked, causing the vehicle power to weaken, fuel consumption increase and other issues, it is recommended not to always drive in the city.
Mr. Lin told Fujian News Broadcasting "News Three Musketeers" that The Ningde Yingzhong 4s Store gave two treatment plans for the vehicle problem.
Option 1: Drive at high speed. The speed of the vehicle needs to reach 100 kilometers per hour, taxi to 80 kilometers, accelerate again, decelerate again, and operate repeatedly. Mr. Lin believes that driving on the highway in this way poses a great danger to the life of the owner.
Scheme two: the vehicle starts in the workshop, and the engine rotates in situ at 3,000 to achieve combustion regeneration. Mr. Lin believes that this plan is to destroy the car, not to repair the car.
Two plans were placed in front of Mr. Lin, but Mr. Lin questioned that this was not a radical maintenance plan, and both plans were immature ways of dealing with them, which he could not accept. However, the 4S store completely ignored his appeal and no longer dealt with it.
From February 1 to 7, 2022, Mr. Lin basically drove high-speed, but the vehicle still had a particle trap blockage of Level 2 on the night of February 7, doubling fuel consumption. Mr. Lin said that this shows that Tanyue's car is defective and cannot be eliminated through so-called high-speed driving and software upgrades.
The Three Musketeers noted that the problems reported by Mr. Lin are not isolated cases, but the general situation of this car, and there are car owners across the country complaining. Some insiders pointed out that the key to the problem of Tanyue is that in the daily car working conditions, its particle trap cannot reach the "regeneration" condition, so the particles cannot be burned, which eventually leads to blockage. In the instruction manual of the Tanyue model, it is marked: "In the normal driving process, the filter will clean itself, if it is impossible to clean itself (such as continuous short-distance driving), the filter will accumulate charcoal and need to be cleaned and regenerated, in order to support the regeneration of particulate filters, the company recommends avoiding long-term short-distance driving." ”
The so-called "run more high-speed is good" solution of 4S stores can only alleviate the temporary problem, and cannot completely solve the fault from the root cause. Because to solve the problem of particle trapper regeneration, the owner needs to maintain a high-speed cruise, when the vehicle speed exceeds 100 kilometers per hour and the exhaust temperature exceeds 700 ° C, the combustion conditions can be met. But in daily life, this kind of operation is not realistic, for most car owners, driving vehicles in urban areas or short distances of low speed driving is the norm, it is impossible to run long distances without moving, and this method will also add a lot of unnecessary costs and safety hazards to the owner.
What is a particle trap? It is a ceramic filter installed in the emission system of gasoline engines. PM particles are captured in the wall surface and wall surface of the carrier through interception, collision, diffusion, gravity settlement, etc., so as to realize the capture of particulate emissions before they enter the atmosphere, when the particulate matter accumulates to a certain extent, the burner will automatically ignite and burn, and the carbon smoke particles adsorbed on it will be burned off, become carbon dioxide discharge, and optimize their own performance. This process, called "regeneration," reduces exhaust emissions and protects the environment.
In response to Mr. Lin's vehicle problem, Fujian News Broadcast "News Three Musketeers" docked with the FAW-Volkswagen 400 service hotline on the 25th, and the customer service staff said that it would be transferred to the relevant personnel for feedback. The Three Musketeers will continue to pay attention.
