What is the Euro 7 Emission Standard?

[OJesse]

Euro 7 Emission Standard: The Euro 7 emission standard stipulates that nitrogen oxide emissions must not exceed 30 milligrams per kilometer, and carbon monoxide emissions are limited to 100-300 milligrams per kilometer. The relevant introduction to the emission standard is as follows: Introduction to Vehicle Emission Standards: Vehicle emission standards refer to regulations on the content of harmful gases such as CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulate matter, soot) emitted from vehicle exhaust. Development Background: With the increasing severity of vehicle exhaust pollution, legislation on vehicle exhaust emissions has become imperative. As early as the 1960s and 1970s, countries around the world established corresponding regulations and systems for vehicle exhaust emissions. Strict regulations have driven the advancement of vehicle emission control technologies, and with the continuous improvement of these technologies, the formulation of higher standards has become possible.
