Along with the more strict control of pollution sources such as fire coal and industrial emission by governments, the proportion of motor vehicle emission in air pollution sources is larger and larger; not only is the motor vehicle one of the main sources of particulate pollution, but also the fuel oil used by the motor vehicle and the emitted nitrogen oxides are important precursors for generating ozone; therefore, the effective monitoring and control of the pollutants discharged by the road motor vehicles are to improve the quality of the ambient air and realize PM 2.5 A necessary way for cooperative control with ozone; the pollutants discharged by the motor vehicles comprise black carbon, particulate matters, nitrogen oxides, VOCs and the like, and the motor vehicles are mainly concentrated on urban roads, so that the pollutants discharged by the motor vehicles comprise the black carbon, the particulate matters, the nitrogen oxides, the VOCs and the likeThe monitoring of the emission pollutants needs to meet two factors of road monitoring and multi-component monitoring at all levels.
Monitoring the emission of pollutants of road motor vehicles is an important means and method for evaluating and treating the emission of pollutants of motor vehicles; at present, in developed countries and regions, the pollutant emission of motor vehicles is reduced by improving the oil quality of motor vehicles, treating tail gas of tail gas pipes of motor vehicles, replacing clean energy, enhancing the monitoring and control of motor vehicle emission and the like.
