Mobile source of pollution is a major factor leading to deterioration of urban air quality, as well as a key point of intensified control of environmental protection and transportation authorities. One of the issues that are most complained about is the dark smoke emitted by diesel vehicles. To better the national control of diesel vehicles and improve the quality of inspections at the diesel vehicle emission inspection stations throughout the country, the promotion of maintenance and inspection system for diesel vehicle continues as part of the project. This year, 5 maintenance service providers were selected, including vehicle manufacturers, distributors and cargo/passenger transportation companies, for field visits by a group of experts. The result of these visits were summarized and used as the basis of the development of “Rules Governing Certification and Management of Maintenance Services for Diesel Vehicles in Use （使用中柴油車保養廠認證及管理要點）” in the hope to establish a verification system for good maintenance service and solidify the diesel vehicle maintenance and inspection for diesel vehicles in use.
For the continuous improvement of inspecting quality of correlation related to the diesel vehicle inspection lines throughout the country, common issues discovered in correlation tests and secondary inspections were compiled for this project, and the “national self-checklist for the diesel vehicle emission inspection stations equipped with dynamometer （全國柴油車底盤動力計排煙檢測站自我檢查表）” for the determination whether the test instrumentation and equipment comply with applicable regulations when inspection staff are performing quality control tests, proficiency tests and national correlation tests. By comparing the outliers summaries of correlation test results between 2012 and 2011, it is found that the outlier points were mostly 1 or less, indicating the correlation tests has helped improve the professional capability of the inspection staff and maintain the inspect quality and credibility of the inspection stations.
As the Environmental Protection Administration amended the diesel vehicle inspection procedures and planned to introduce smoke opacimeter, this project aimed to first evaluate the feasibility of local diesel vehicle inspection stations, supervisory authorities, and maintenance services performing regular inspections. Secondly, the smoke opacimeter type equipment specifications were collected from Europe, the US and Japan and compiled, and experts in the field of diesel vehicles consulted to develop Taiwan’s own performance specifications for “smoke opacimeter equipment for diesel vehicles.”
