Research On Driving Condition And Emission Characteristics Of Bus

With the improvement of living standards in Qingdao city, the car has become an essential for many families. Cars bring convenience to people’s life, at the same time; the cars exhaust pollution is becoming more and more serious, such as persistent haze weather. So, Qingdao city should take the motor vehicle emission pollution control as an important work to do. The bus is most people’s traveling vehicles in Qingdao city. The bus exhaust pollution is one of the key control objects.This paper conducted a survey of the status of air quality traffic conditions and vehicle development in Qingdao City. Understand the status of vehicle emission pollution of Qingdao city. Application of GPS to the representative of the21bus routes, which were selected for data acquisition, and the use of fixed step analysis method for data analysis, constructs the driving cycles in Qingdao city. And compared with the running condition of other countries and regions, the comparative analysis with a greater difference, but there are some similarities.Using the MOBILE6.2model to simulate the emission factors in Qingdao city, which slightly bigger than the actual emission factors, also need further correction parameters. Analyzing the condition impact on emissions. Comprehensive analysis shows that the bus in high speed can reduce the emissions of buses. Finally put the conclusion as the basis, to protect and control of the motor vehicle emissions, and puts forward the corresponding measures and Suggestions for Qingdao City.
