本計畫致力於國內近600萬輛使用中汽油車之污染管制策略研擬，本年度主要工作包括OBD定檢制度研擬、保養維修污染改善成效評估、以及使用中車輛污染排放調查。 因應四期車輛搭載OBD系統規定，引進歐美OBD檢驗程序與設備進行檢驗示範運行，評估OBD查驗納入定檢項目可行性。本年度係取得2,582組有效檢驗結果，具故障碼者約佔0.56%，準備就緒狀態異常者則約佔8%。依據本年度執行成果，建議OBD定檢可以MIL狀態目視檢查為先，同時加強OBD資訊宣導，再逐步擴增檢驗設備、項目與標準。 為因應未來OBD檢驗可能導入現行定檢程序，本計畫廣邀監理與代檢人員，分別於北中南3處辦理OBD實車檢驗觀摩會。此外，為瞭解原廠體系有關空氣污染防制設備檢修程序與教育訓練內容，計完成國內5大車廠體系之訪查作業；結果指出，其檢修技術多仰賴OBD，對傳統車輛之污染改善，僅依技工經驗，然其減污成效不彰。 今年度租用使用中汽油車共25輛，分別執行FTP-75及NEDC測試。結果顯示，使用中車輛之FTP-75超標率為46%，其中2期車實際劣化情形較指定劣化嚴重。兩者於污染、耗能測值均呈高度正相關；其中4期車之判定結果一致率高達90%。污染排放主要產出於冷啟動及高速段，建議可針對測試程序進行調整。污染排放與耗能受空調開啟與否影響明顯，CO與NMHC排放量之差異可達1倍以上。

With the project devoting to formulating the pollution control strategy on close to six million gasoline-fueled vehicles currently in use in Taiwan, the current year’s primary work includes formulating the on-board diagnostics (OBD) routine inspection system, maintenance/repair plant pollution improvement result evaluation, and in-use vehicles’ pollution discharge survey. In response to stipulations for pairing an OBD system on all phase-four vehicles, the OBD inspection procedure and equipment prevailing in Europe and the United States have been introduced to conduct the demonstrative inspection implementation, by which to evaluate the feasibility of streamlining the OBD inspection as part of the routine inspection items. The current year has obtained a total of 2,582 sets of valid inspection results, with 0.56% of those containing faulty code, and 8% of those being found with anomaly in the readiness status. Based on the current year’s implementation result, it is recommendable that the OBD routine inspection may heed to MIL status visual inspection as a precedence, and also stepping up the OBD information campaigning before gradually expanding and adding the inspection equipment, items and standards. In response to the OBD inspection likely to be inducted into the existing inspection procedure in the future, the project has widely invited DMV and consigned inspection personnel to stage three OBD car inspection demonstrations in the northern, central, and southern regions. In addition, to decipher the original vehicle manufacturers’ relevant air pollution prevention equipment inspection/repair procedure and content of the orientation training, the project has completed the visitation audit work on five major automotive plants, and the result indicates that their inspection/repair technology largely relies on OBD, and in pollution improvement on conventional vehicles, it merely relies on the technicians’ experience, but the pollution reduction result has been lackluster. A total of 25 gasoline-fueled vehicles in use this year on lease have been put through the FTP-75 and the NEDC tests respectively. The FTP-75 test results show that the amount of pollution in 46% of the tested vehicles exceeds the new vehicle emission standard, and among them, the actual state of deterioration among phase-two vehicles is found to be severe than the designated deterioration. In terms of pollution, the fuel consumption ratings between the two types of driving cycles have high positive correlation; the consistency on the rendering results among phase-four vehicles on the two types of driving cycles has reached as high as 90%. With pollution discharge mainly generated at cold start and at high-speed increments, it is recommendable that adjustment can be made to the testing procedure. Pollution discharge and fuel consumption are ominously affected by the use of air-conditioning, and the result finds the differential in discharge volume of CO and NMHC can reach twice or more between the two situations.
