Research on Emission Standards and Control Technology of Heavy Commercial Diesel Vehicles

Abstract

More than 70% of the pollutants produced by heavy commercial diesel vehicles are from exhaust, which contains a large number of harmful substances. These substances are discharged into the air with vehicle exhaust, polluting the environment. In addition, the emission height of automobile exhaust is mainly between 0.3 meters and 2 meters, which is exactly the breathing range of human body, thus posing a threat to human health. At present, China has improved the management of exhaust emission testing of heavy commercial diesel engines, and the emission standard has been gradually raised from the national V standard to the national VI standard. This paper mainly expounds the hazards of different pollutants, studies on the national emission standards and control technologies, and provides references for the related industry research.
