On March 15th, CCTV exposed, a number of 4S stores in the three major domestic auto companies, generally have minor illnesses and overhauls, exaggerating vehicle breakdowns, and profiting from them. In response, Dongfeng Nissan, Mercedes-Benz and Shanghai Volkswagen responded to the outside world for the first time, and will conduct follow-up investigations to improve terminal service standards and protect consumer rights. The China Automobile Dealers Association also called on domestic auto dealers to operate in good faith and strengthen institutional development to fundamentally eliminate some dealers’ illegal behavior.
Three car companies to strengthen channel management According to CCTV exposure, Dongfeng Nissan, Shanghai Volkswagen and Mercedes-Benz are located in many domestic 4S stores. In the ordinary failure of ignition coil loosening, it is only necessary to re-connect the ignition coil and restart the system to fix it. However, they all suffered from the deliberate misrepresentation and exaggeration of vehicle failures in 4S stores.
Subsequently, Dongfeng Nissan, Shanghai Volkswagen and Mercedes-Benz have successively issued announcements, which will investigate the channel dealers and standardize relevant behaviors.
Among them, Dongfeng Nissan issued a statement at the first time, saying that Dongfeng Nissan attaches great importance to the news that the Dongfeng Nissan brand authorized dealers have “non-integrity management†in the 3.15 party. The special working group conducted an investigation. Here, please owners and the community believe that Dongfeng Nissan will always adhere to the "customer first" principle, strengthen the supervision of terminal services at the same time, and prevent similar situations from happening. The follow-up investigation will promptly communicate with all sectors of the community and the majority of Dongfeng Nissan owners.
Mercedes-Benz also said that the misconduct of individual dealers is an infringement of the interests of consumers, and it is irresponsible to the brand. In this regard, Mercedes-Benz firmly opposes, will always regard customer satisfaction as the top priority of the work, will immediately carry out a thorough investigation and urge the relevant dealers to carry out rectification. And further strict regulation of after-sales maintenance hype in the dealer network to prevent such incidents from happening again. Mercedes-Benz will promptly inform the public about the progress of the matter.
Shanghai Volkswagen said that it has launched a survey of three dealers in Tianjin. Shanghai Volkswagen protects users' rights and interests, and improving customer satisfaction has always been the top priority. It will further strengthen supervision and management of the 4S shop's maintenance service process.
Calling dealers to operate in good faith, in addition to the three car companies said that they will strengthen management, the China Automobile Dealers Association also called on dealers to do business with integrity.
It is reported that the China Automobile Circulation Association has issued the "Integrity Management of Automobile Circulation Industry" proposal to the whole industry before "3·15", requiring the majority of automobile dealers to operate with integrity and self-discipline.
China Automobile Circulation Association said that the focus of automobile consumption has been transformed from buying a car to using a car. The standard operation and quality service of car dealers is an important guarantee for dealers to establish service brands in the new era and achieve sustainable development.
In response to the problem that some dealers were exposed to “small illnesses and big governance†in March 15th, China Automobile Dealers Association called on auto dealers to conduct self-examination and self-correction in pre-sale, in-sale, and after-sales maintenance, and improve the self-discipline mechanism. And for the implementation of the "three guarantees" weak enterprises and the behavior and phenomena of non-standard operation are resolutely exposed to further enhance the dealers' marketing level and after-sales service quality.
At the same time, the China Automobile Dealers Association will cooperate with relevant departments to formulate national standards or industry standards such as "Automobile After-sales Service Specifications", "Automobile Service Testing Standards", "Automobile Dealer Marketing Service Specifications", and organize distributors. Standardization and benchmarking have fundamentally established a scientific automobile after-sales system and supervision mechanism to improve the legalization level of automobile after-sales service work.
Land Rover has launched a software upgrade for CCTV to expose some consumers to buy Jaguar Land Rover Aurora, and found that when the vehicle is engaged in the R block, there is a gearbox failure; or the vehicle suddenly stalls during normal driving.
Land Rover China also issued a statement, "About the issue of importing Land Rover Range Rover Aurora 9-speed transmission, Land Rover China and authorized dealers attach great importance to it. We apologize for the inconvenience and trouble caused by consumers," Land Rover said.
Customer satisfaction has always been the long-term pursuit of Land Rover China, and will continue to provide better products and services to Chinese consumers. Thanks to the community for their attention to the Land Rover brand. Regarding the progress of the incident, we will actively cooperate with relevant departments and maintain communication with everyone.
It is reported that Land Rover China has been actively developing solutions after receiving feedback from some customers. Since January 19, 2015, the Land Rover Range Rover Aurora has been imported for the period from 2014 to 2015 (the vehicle identification code range is LV000001). -LV996116) Proactively introduced the latest transmission software upgrade measures, and has already filed the solution in relevant national departments. This upgrade is continuing, and we will work with our distributors to accelerate the fastest.
The 2015 domestic Land Rover Range Rover Aurora, which has been sold since March, is currently in the latest state of the 9-speed gearbox installed on the model, and there is no problem with the fault batch.
Working principle of integral Alternator
When the external circuit through the brush excitation winding is energized, it generates a magnetic field, the claw pole magnetized N pole and S pole. When the rotor rotates, flux alternately in the stator windings changes, according to the electromagnetic induction principle knowable, the stator three-phase winding produced alternating induced electromotive force. This is the alternator power generation principle.
The original motivation (i.e. engine driven DC excitation of synchronous generator rotor, with the speed of n (RPM) rotation, three-phase stator winding induction AC voltage. The stator winding if access to electricity load, motor with AC power output, after internal generator rectifier bridge will convert AC to DC power is output from the output terminal.
The content of AC generator stator winding and rotor winding and the three-phase stator winding according to the mutual difference distribution of 120 electrical degrees on the shell PTT and rotor winding is composed of two pieces of claw pole. When the rotor windings connect when DC is two pole excitation, the formation of N and S poles. Magnetic pole starting from N, through the air gap into the stator core to the adjacent S. Rotor once rotated, the rotor winding will cuts the magnetic lines of force and mutual difference of 120 electrical degrees of sinusoidal EMF in stator windings, the three-phase alternating current, again through the diode rectifier changed to DC output.
When the switch is closed, the current is supplied first by the battery. Circuit:
The positive battery, charging indicator, regulator, excitation winding, contact ground, negative battery. At this time, due to the current through the charging indicator light, so the exhibit of lanterns.
But after starting the engine, with the increasing speed of the generator, the terminal voltage of the generator is increasing. When the generator output voltage and the battery voltage is equal to the generator "B" and "d" end of equal potential. At the same time, the charging indicator due to the ends of the potential difference is zero and extinguished. The generator has been instructed to work properly, the excitation current is supplied by the generator itself.Generator three-phase winding three-phase AC electromotive force generated by the resistance after diode rectifier, DC output, power supply to the load and to the battery charging.
