Can China III vehicles enter Beijing?
1 Answers
China III vehicles can enter Beijing, but they are not allowed to drive within the Sixth Ring Road. The main emission standards for China III vehicles are: HC emissions below 0.2 grams per kilometer, CO emissions below 2.3 grams per kilometer, NOx emissions below 0.15 grams per kilometer, with no PM requirement. The purpose of setting vehicle emission standards is to control and reduce vehicle pollutants and improve ambient air quality. Vehicle pollutants include: carbon monoxide, hydrocarbons, nitrogen oxides, and PM harmful gases. Solutions for vehicles failing to meet emission standards include: 1. Cleaning the fuel injector; 2. Replacing piston sealing rings; 3. Using higher quality fuel.
