Audi diesel engine_Tragedy and global market accessLessons Audi is one of the world-renowned luxury car brands. Its diesel engine manufacturing technology has always been highly respected by the industry and consumers, and is regarded as the leader in the industry. And benchmark. However, since 2015, Audi has been severely criticized and punished many times for its diesel engine emission problems. The once exciting diesel engine has now become a nightmare for car companies. Audi was forced to recall millions of cars equipped with its diesel engines, and this series of scandals was very shocking and painful. Background First of all, let's take a look at the emission problems of Audi diesel engines in recent years.Since its exposure in 2015, the emission problem of Audi diesel vehicles has attracted wide attention among consumers and the media in Europe and the United States. At that time, the U.S. Environmental Protection Agency accused Volkswagen of using "software cheating" to forge data in the exhaust emission test. The data was immediately seized by the Dubai police. The relevant departments began an investigation and found that not only Volkswagen had such a problem, but also its Audi and Porsche to varying degrees. Kind of problems. In this emission crisis, Audi diesel vehicles have been confirmed to have illegal emissions, and the problem involves millions of cars around the world, which has had a great impact on Audi's brand image. The reason for the problem, why does Audi, a world-renowned car brand, have emission problems because of diesel engines? According to the adjustmentIt was found that the emission problem of Audi diesel engine was caused by a problem of pollution control technology called "urea reduction catalyst". This technology is a device used by vehicles to reduce exhaust emissions, but because it is vulnerable to the harsh environment, the concentration of the catalyst output will change, thus affecting the emission performance of the vehicle. In addition, because Audi's diesel engine technology itself is relatively mature, there is a large contradiction between its engine performance and emission performance. This contradiction leads to the problem of "software cheating" when installing emission control equipment. As a result, the emission problems of Audi diesel engines are self-evident. Of course, it is undeniable that the internal management and control of the company is also indispensable in the emission problem of Audi diesel engines.In order to improve market competitiveness, the company's management team may push the technical department to push the engine to the limit, and even use some means, such as using some non-compliant emission control equipment, which is very dangerous. Lesson So, against the background of the scandal of the Audi diesel engine, what kind of revelation and lesson is there for us ordinary people? First of all, we should soberly realize that the cars produced are not only competitive and high-performance, but also need to move towards environmental protection and sustainability. Just like the current rise of new energy vehicles, this is an inevitable trend in the development of the automobile industry. Automobile enterprises should regard innovation as a top priority and constantly improve core technologies, so that automobiles can better meet the requirements of environmental protection regulations. Secondly, the management team of the enterprise should also do a good job.The constraints and management of the technical department, and strictly abide by relevant laws and regulations, shall not sacrifice the interests of consumers and the health of the public for the sake of competition or temporary interests. Finally, consumers should also become the main force of environmental protection. We should learn about environmental protection, encourage ourselves to buy green and environmentally friendly cars, and play the role of "green consumers". Perhaps this is the best way to promote the better development of the automobile industry. In a word, the emission problem of Audi diesel engines has taught us to a certain extent that even well-known car brands cannot ignore environmental protection and violate environmental regulations. Each of us should use our own strength to contribute to environmental protection.
