·Environmental Protection Department: Volkswagen diesel vehicle exhaust is involved in 1900 vehicles in China
Related issues Diesel vehicles have not yet been produced in China, but the import and sales of the same type of engine vehicles involved in the United States involved more than 1,900 vehicles in charge of the Ministry of Environmental Protection, the media said that the Ministry of Environmental Protection recently focused on the media The problem of waste gas fraud was investigated. The forced circulation pump does not rely on the centrifugal force of the impeller to the liquid, but uses the thrust of the rotating impeller blades to make the sent liquid flow along the direction of the pump axis. When the pump shaft is driven by the motor to rotate, because the blade has a certain helix angle with the axis of the pump shaft, a thrust (or lift) is generated on the liquid, and the liquid is pushed out and discharged along the discharge pipe. When the liquid is pushed out, a partial vacuum is formed at the original position, and the liquid outside will be sucked into the impeller along the inlet pipe under the action of atmospheric pressure. As long as the impeller keeps rotating, the pump can continuously suck in and discharge liquid. The forced circulation pump works by using the horizontal thrust along the direction of the pump axis generated by the rotation of the impeller, so it is also called a horizontal axial flow pump. Mainly used in the evaporation of diaphragm method caustic soda, phosphoric acid, vacuum salt production, lactic acid, calcium lactate, alumina, titanium dioxide, calcium chloride, ammonium chloride, sodium chlorate, sugar, molten salt, paper, waste water and other industries. Concentration and cooling, in order to improve the production capacity of the equipment, increase the heat transfer coefficient of the heat exchanger for forced circulation. Therefore, it can also be called an axial flow evaporative circulation pump.

Some media recently reported that the US Environmental Protection Agency found that diesel vehicles produced by Volkswagen Group of Germany installed emission cheat software to identify whether the vehicle is in a state of detection and regulate vehicle exhaust emissions, resulting in excessive emission of nitrogen oxides from the exhaust gas during actual operation of the vehicle. 40 times the limit. The problem vehicles involved a total of 482,000 diesel engines such as Jetta, Audi A3, Beetle, Golf and Passat produced by Volkswagen Group in 2009. According to the US Clean Air Act, the US Environmental Protection Agency can impose a maximum fine of $37,500 on each vehicle, with a total fine of $18 billion.
According to the Volkswagen Group, approximately 11 million vehicles worldwide may be affected, with the exception of the United States, which are mainly distributed in European countries. Following the United States, the European Union, Germany, Canada, India and South Korea have also issued statements to investigate.
The Ministry of Environmental Protection attached great importance to this incident and immediately investigated the production and import of the above-mentioned problem models in China, and asked Volkswagen (China) Investment Co., Ltd. to explain the situation. According to the report of Volkswagen (China) Investment Co., Ltd. and the preliminary investigation results of the Ministry of Environmental Protection, due to the constraints of diesel engine technology and oil products, the development of diesel passenger vehicles in China is slow, and related problems have not yet been produced in China, but imported sales are carried out. There are more than 1,900 engine vehicles in the same case. At present, Volkswagen (China) Investment Co., Ltd. is investigating whether there are related problems in these vehicles. The Ministry of Environmental Protection will pay close attention to the request of the company to report the progress of the investigation at any time, and actively cooperate with relevant departments to strengthen the environmental protection compliance of imported vehicles to ensure that vehicle emissions are up to standard.
