Mobile pollution source is one of the main causes that generated air quality deterioration in metropolitan areas, and it is also the control focus strengthened by environmental and traffic authorities. Therein, the black smoke from the diesel vehicles is highly condemned by the public. In order to improve black smoke from diesel vehicles, the Environmental Protection Agency not only conducts non-periodical inspection and audit but also promotes diesel vehicle inspection/maintenance system, conducts diesel vehicle maintenance plant certified self-management combined with Clean Air Zone, as well as plans to install after-treatment （diesel particulate filter）in garbage trucks to operate and maintain for five years. Therein, maintenance plant certified effect, take original vehicle manufacturer as an example, the proportion of re-notification of non-certified original vehicle manufacturer is 6.4%, and the proportion of re-notification of certified original vehicle manufacturer is 2.5%. It shows that promoting the certification of diesel vehicle maintenance plant by the Environmental Protection Agency can strengthen pollution control devices checked and repaired, and then making pollution improved efficiently.
As for diesel particulate filter, this plan summarizes 280 garbage trucks installed diesel particulate filters by Taipei city and other 5 cities, and the overall change rate of improvement is up to 85%, and the change rate of horse power is about -0.2%. According to the results of demonstration runs at the present stage, only by implementing the acceptance of diesel particulate filters, choosing proper vehicles prudenly, and implementing the periodical regeneration as well as maintainance of diesel particulate filters can it make sure the expected performance of diesel particulate filters.
To continue improving the relevant test quality of nationwide diesel vehicle inspection lines, this plan has summarized correlation tests as well as common retest problems in recent years, and conducts educational training for nationwide diesel vehicles inspection personnel, including common disputes about inspection, safeguarding democratic interests and rights, fulfilling standard test procedures, calibration as well as repair of test equipment and Quality Assurance and Quality Control in laboratory, etc. Additionally, lecturers with practical experiences are invited to give lessons, and then enhance the professionalism of inspection personnel and implement Quality Assurance and Quality Control in smoke test station.
Finally, statistics of audit of diesel vehicles in 2015, including the amount of TSP reductions about unqualified re-inspection, adjustment before inspecting and self-management. It amounts to 669.3 metric ton. This plan summarizes the budget of nationwide diesel vehicle plans is 181,166,120 dollars in 2015, and calculates the cost of cutting down a kilogram of TSP is about 271 dollars.
