Europe's "most stringent" emission standards in history

Europe's "most stringent" emission standards in history.

Car exhaust has always been criticized because its ingredients are mostly hazardous:

CO (carbon monoxide): an intermediate product of incomplete oxidation of fuel oil, which is generated when oxygen is insufficient. The concentration of the mixed gas and the uneven mixture will increase the CO in the exhaust gas;

HC (hydrocarbon): Unburned substances in fuel oil, some of which are discharged in the future due to uneven mixture gas and cold combustion chamber wall;

NOx (nitrogen oxide): Like hydrocarbons, they are products of incomplete combustion of fuel oil;

PM (Particles, soot): Like carbon monoxide, a substance produced by oxygen depletion during combustion is most obvious in diesel engines, which is one of the reasons why some trucks used to smoke black smoke in previous years.

Since the exposure of VWˇ°emissions gateˇ±, the EU has become increasingly strict in the development and regulation of vehicle emission standards. In February 2014, the European Commission announced the ˇ°most strictˇ± carbon dioxide emissions regulations in the history of automobiles. In the next six months, EU passenger cars are subject to stricter emission standards.

From January 1 next year, 95% of EU passenger cars should emit no more than 95 grams of carbon dioxide per kilometer. To 2021, all vehicles must meet this standard. In contrast, Japan hopes to control CO2 emissions to 122 g/km by 2020 and the United States to 97 g/km in 2025.

However, the survey shows that most European automakers are unable to meet this standard, and companies that do not meet the requirements will face a fine of 95 euros (about RMB 741.78) for every 1 g of displacement.

According to the emissions released in 2018, by 2021, Volkswagen, the world's largest automaker, will face the highest fine, which will pay 9.19 billion euros (about 71.4 billion yuan); Peugeot Citroen Group will be fined 5.39 billion yuan. Euro (about RMB 421.3); Renault third, will be fined 3.57 billion euros (about RMB 27.9 billion).

Beginning in 2019, a storm from the transition from fuel vehicles to electrification began to sweep the European automakers.

In September last year, Volkswagen released a comprehensive electric vehicle program. Under the guidance of the comprehensive electrification strategy ˇ°Roadmap Eˇ±, by 2020, Volkswagen will launch 10 new energy vehicles in China, and the sales of domestic new energy vehicles will reach 300,000 units; by 2025, Volkswagen will provide 80 models. New energy vehicles, covering all Volkswagen models.

Second, optimize the car exhaust aftertreatment. From Euro 5 to Euro 6, the biggest challenge for diesel engines is nitrogen oxides. For diesel vehicles of the compact class and above, especially large cars, more catalytic converters, SCR selective catalytic reduction equipment, will be installed in the future. It relies on nitrogen in urea to reduce harmful nitrogen in nitrogen oxides. Nitrogen oxygen sensors are becoming more and more important in the treatment of vehicle exhaust emissions.
