The report that the use of software cheating in the emissions test of Volkswagen's diesel vehicles caused a global sensation. After the US exposure, many countries also began to investigate the public fraud to confirm whether there is similar behavior in the public vehicles.

This resulted in a tens of times more than the actual NOx emissions of vehicles equipped with this type of engine.
In order to save costs, Volkswagen used LNT (Lean NOx Trap) lean-burn nitrogen oxide adsorption converter on some diesel vehicles instead of SCR (Selective Catalyst Reduction) selective reduction system. Compared to SCR, LNT costs less, but not as effective. Therefore, the public used fraudulent device fraud to pass the test. In the United States, NOx emission standards are far more stringent than in Europe and China. Since the beginning of last year, institutions and individuals have started testing for doubts about the performance of Volkswagen diesel vehicles, and this year it was finally exposed.
After the United States was exposed, the European Union, Germany and Canada have announced or will announce relevant investigations, and the case has also expanded to Asia, and India and South Korea have also issued statements to investigate. Chinese consumers are also concerned about whether the mass fraud vehicles affect the domestic market.
