What is the Euro 7 Emission Standard?
2 Answers
Euro 7 Emission Standard: The Euro 7 emission standard stipulates that nitrogen oxide emissions must not exceed 30 milligrams per kilometer, and carbon monoxide emission limits range from 100 to 300 milligrams per kilometer. The relevant introduction to the emission standards is as follows: Introduction to Vehicle Emission Standards: Vehicle emission standards refer to regulations on the content of harmful gases emitted from vehicle exhaust, including CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulate matter, soot). Development Background: With the increasing severity of vehicle exhaust pollution, legislation on vehicle exhaust emissions has become imperative. Countries around the world established corresponding regulatory systems for vehicle exhaust emissions as early as the 1960s and 1970s. These strict regulations have driven advancements in vehicle emission control technologies. As these technologies continue to improve, the formulation of even higher standards has become possible.
The Euro 7 emission standard is Europe's latest vehicle exhaust regulation, significantly stricter than Euro 6. It is set to be implemented around 2025, with the primary goal of reducing harmful gases such as nitrogen oxides (NOx) and particulate matter. For instance, the NOx limit for passenger cars will drop from 60 mg/km to below 30, with even stricter particulate monitoring. The testing method shifts from laboratory conditions to real-world driving scenarios, covering various road conditions. I believe this will greatly drive advancements in automotive technology, requiring more efficient after-treatment systems, such as upgraded catalysts. While costs may rise, environmental protection is paramount, helping to reduce urban smog and health risks, marking clear overall progress.
