For the 2013 FAW-Volkswagen Jetta models, except for some models sold in regions like Beijing, Shanghai, and Guangzhou which comply with the China V standard, most other regions adhere to the China IV standard. Specific details are as follows: Automobile Emission Standards: These standards regulate the permissible levels of harmful gases emitted from vehicle exhaust, including CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulate matter, soot). Automobile Emissions: These refer to the harmful gases emitted from exhaust, such as CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulate matter, soot). These gases are byproducts of the engine's combustion process. The causes of these harmful emissions vary. CO is an intermediate product of incomplete fuel oxidation and is produced when oxygen is insufficient. High concentration of the air-fuel mixture and uneven mixture distribution can increase CO emissions in the exhaust.
