Measure Method And Influencing Factors Analysis On PM2.5of Automotive Exhaust

In recent years, the rapid development of the automotive industry and national gradually improve the quality of life, has become the car of the people are not beyond the reach of consumer goods. With the car, the number of truck and bus industries increased significantly worsening the impact on the environment, traffic increased vehicle emissions should strengthen its pollution prevention and control efforts. With the increasing expansion of environmental pollution on human and social development, resulting in a serious impact. With the increasing expansion of environmental pollution on human and social development, resulting in a serious impact. Ownership of motor vehicles showed a rising trend, automobile exhaust on the atmospheric environment and human health hazards are further revealed. The condition and quality of the oil formation and exhaust gas is directly related to the motor vehicle. National ownership of motor vehicles reached about more than200million vehicles in recent years, has become the emissions factors haze, photochemical smog and other air pollution. Currently, the domestic automobile exhaust emission detection method is two-speed idle and BASM both methods. But the two standard vehicle exhaust emission limits on car emissions of pollutants PM2.5, are entirely consistent with our national conditions debatable. Based on the growing problem of PM2.5pollution caused by vehicle emissions become, therefore, the study of PM2.5caused by vehicle emissions caused by air pollution problem has aroused concern.The master is based on a different displacement models were compared with the normal idle speed when working condition arising from automobile exhaust law in PM2.5concentrations, and thus provide a basis for automobile exhaust PM2.5detection methods. Query statistical results, currently occupies much larger than the amount of gasoline and diesel hybrid vehicles and electric vehicles, as PM2.5pollution of automobile exhaust, gasoline vehicle emissions are directly related, which made for gasoline vehicle emissions PM2.5to do research, based on PM2.5pollution caused by vehicle emissions resulting from an increasingly serious problem, therefore,-the study of PM2.5caused by vehicle emissions caused by air pollution problem has aroused concern. PM2.5article on vehicle emissions factors were analyzed in order to provide the basis for vehicle emissions in PM2.5detection methods for how to collect exhaust, exhaust gas collected for analysis of gasoline exhaust seek variation in PM2.5, the in order to reduce vehicle exhaust emissions of PM2.5from the root, to reduce the pollution of the environment.
