Beijing has issued the standard NOx rapid detection method for three heavy vehicle emission pollution control standards

For control of heavy duty truck nitrogen oxide (NOx) emissions pollution, the Beijing municipal government recently approved released three heavy vehicle emission pollution control local standards, respectively is: the heavy duty truck nitrogen quick detection method and emissions limits "(DB 11/1476-2017) (hereinafter referred to as the" NOx rapid detection method "), the heavy automobile exhaust emission limits and measurement methods (the first Ⅳ OBD method, phase Ⅴ) (DB 11/1475-2017) (hereinafter referred to as the "OBD method") and the heavy vehicle exhaust pollutant emission limits and measurement methods (on-board phase IV, V) (DB 11/965-2017) (hereinafter referred to as "the vehicle-mounted method").Among them, the on-board method "and" the OBD method "two standards is mainly used in the production and sale of heavy-duty vehicle emission inspection, automobile production enterprises should be in strict accordance with the standard production sales target vehicle;The "NOx rapid detection method" is mainly used for the inspection of NOx emission in heavy vehicles, and the owner needs to do the daily maintenance.The implementation of the three standards will enhance the vehicle emission control level and the emission stability of the heavy vehicle manufacturers, and improve the supervision capacity of the vehicles in the vehicle.

Research shows that NOx pollution from heavy vehicle emission is the main source of vehicle emission pollution.Beijing heavy vehicles accounted for about 4% of the city's motor vehicle ownership, but its emissions of NOx accounted for more than 50% of the motor vehicle emissions, plus the outgoing into Beijing, transit heavy duty truck, emission pollution.The pollution control of heavy vehicle emission has become the focus of the city's automobile emission pollution control.The three standards will be the main basis for the enforcement of NOx emissions.
