中文摘要	本計畫致力於國內約600萬輛使用中汽油車之污染管制策略研擬，本年度主要工作項目包括OBD定檢制度研擬及評估、使用中汽車行車污染排放調查與歐美使用中GDI汽車PM排放管制文獻蒐集。今年共取得5,375筆OBD檢驗數據，由統計分析結果顯示，自小貨及營小客等行駛里程較高之族群，OBD故障出現比例最高，於具故障碼車輛中以動力系統相關通用碼查獲率最高，未就緒項目中以觸媒及含氧感知器查獲率最高。追蹤近2年自小客2008年出廠者之故障查獲率，顯示其有微幅上升的趨勢，宜持續觀察車齡與故障查獲率變化，依今年試行成果，建議可先導入現行惰轉標準加嚴及故障燈目視檢查方案。本計畫併同歷年使用中四期車之行車型態抽測結果進行分析，結果顯示23部OBD具故障碼者，排氣定檢均合格，卻有17車行車污染超過新車標準，其超標率約74%，顯示OBD檢驗較惰轉檢測更具污染鑑別度，該等樣本中以觸媒劣化者超標率100%最高，另於3種管制污染物中，以NOx超標率69%最高，顯見OBD可有效查知觸媒及NOx異常情形。 GDI汽車PM管制文獻蒐集成果，目前歐美仍未在車輛定檢實施微粒排放之量測與管制。然而，藉由OBD感測元件監控汽車濾煙器的微粒削減效率卻是可行的，未來管制使用中汽車OBD功能狀況，應可一併解決GDI汽車微粒排放問題。

摘要	The plan focuses on the research, estimation and establishment of the pollution control strategy for over 6 millions of automobiles in use in our country; in this year, the three major objects of the plan are as follows: 1. the estimation of the feasibility of adding the on-board diagnostic (OBD) system to the current periodical automobile inspection process and the establishment of the relevant projects thereof; 2. the selective emission pollution test operation for automobiles conforming to the environmentally-friendly 4th emission standard; 3. The collection operation of the current automobile particulate matter control statuses in US and Europe for automobiles with gasoline direction injection (GDI) engine. In this year, the plan has acquired 5,375 pieces of OBD test data in total; the statistics result shows self-use van, business sedan or other kinds of automobiles with high VMT will have higher breakdown rate. Among the automobiles with diagnostic trouble codes, the most codes are the international universal codes related to the dynamical system. Among the abnormal items of the readiness status (RS), the most items are the catalyst sensor and the oxygen sensor. According to the selective test results for the last two years, the breakdown rate of the automobiles belonging to self-use sedan manufacturing in 2008 slightly increases; it is suggested to keep observing the change of the relation between the automobile age and breakdown rate. According to the research of the plan, it is suggested to add the inspection item of visually inspecting the malfunction indicator lamp (MIL) to the current periodical inspection process or make the coasting emission standard stricter. The plan collects the selective test results of the automobiles meeting the 4th emission standard in recent years, which show 23 automobiles with OBD malfunction code obtain eligible emission test value from the periodical inspection; however, the emission test values of 17 of these automobiles exceed the emission standard for new automobile, and the over standard rate is about 74%, which show the OBD test items have higher pollution discrimination than the current emission inspection standard. Among these samples, the pollution over standard rate of the automobiles with abnormal catalyst is highest, which is up to 100%. Among the three controlled pollutants, the NOx has highest over standard rate, which is up to 69%; it is obvious that the OBD can effectively detect the abnormal situations of catalyst and NOx. According to the literature collection results of the automobiles with GDI engine and PM control, US and Europe, currently, have yet to implement the PM emission measurement and control in the periodical automobile inspection. However, it is feasible to monitor the gasoline particulate filter (GPF) of automobiles in order to reduce the PM emission; it is possible to simultaneously solve the PM emission problem of the automobiles with GDI engine by controlling the OBD function statuses of the automobiles in use.
