移動污染源係造成都會區空氣品質劣化的主要原因之一，也是環保 及交通主管單位加強管制重點，其中柴油車排放之黑煙最令民眾所詬 病。為改善柴油車黑煙排放，環境部除執行柴油車不定期檢驗與稽查， 亦加強柴油車管制措施，如：協助 1~3 期大型柴油車汰舊換新、加裝空 氣污染防制設備或調修燃油控制系統，並制訂分年目標，統計 106 年至 112 年 10 月，已協助國內 1~3 期之大型柴油車計 83,333 輛進行污染改善， 大型柴油車補助措施已削減 TSP 約 4,763 公噸（含 PM10 約 4,193 公噸、 PM2.5 約 3,708 公噸）、NOx 約 64,677 公噸。 全國於 112 年至 10 月已汰舊 1~3 期大型柴油車計 3,290 輛，其中申 請補助案件，包括汰舊換新、過戶換新車，共計 3,077 件。 本計畫已評析無負載急加速不透光率試驗法、全負載 80％試驗點檢 測 NOx 與 NH3 排放，以及 OBD 診斷設備等各稽查工具之優缺點與污染 減量成本效益。其中，考量 OBD 監控之控制元件涉及 PM 與 NOx 排放 等且 OBD 診斷設備效益最佳，故規劃 5 期以後車輛採 OBD 診斷設備並 於自主管理標章規範中，納入科技稽查工具。 計畫期間完成全國柴油車排煙檢測站相關性測試作業，結果顯示全 國柴動站檢測品質良好。最後，統計近 8 年，藉由柴油車不定期稽查， 全國平均不透光率由 0.82m-1 逐年下降至 0.33m-1，顯示柴油車有逐年改 善。

Mobile source pollution is one of the major reasons for the deterioration of air quality in the metropolitan area and the key point which the environmental protection and traffic authorities focus on. Besides, emitting the black smoke from diesel vehicles is most series problem blamed by citizens. In order to improve the emission by diesel vehicles, the Ministry of Environment (MOENV) has implemented not only, irregular inspections, but also enhance the control measures for diesel vehicles. For example, assist Tier-1 to Tier-3 heavy-duty diesel vehicles (HDDVs) to be replaced for new ones, install air pollution control equipment or repair fuel injection system, and it has formulated annual targets for achievement. From 2017 to October 2023, MOENV has assisted as many as 83,333 Tier-1 to Tier-3 HDDVs to improve pollution, the subsidy measures for large diesel vehicles have reduced TSP by approximate 4,763 metric tons (including PM10 4,193 tons and PM2.5 3,708 tons), and NOx approximate 64,677 metric tons. Until October 2023, there are 3,290 Tier-1 to Tier-3 HDDVs have been eliminated. Among the applications for subsidies, include eliminating Tier-1 to Tier-3 HDDVs and transferring for new vehicles, totaling 3,077 cases. This project has evaluated the advantages, disadvantages, and cost-effectiveness of emission reduction of various inspection tools such as the no-load free acceleration opacity test method, the full-load 80% test to inspect NOx and NH3 emissions, and OBD diagnostic equipment. Among them, considering that the control components of OBD monitoring involve PM and NOx emissions, and OBD diagnostic equipment is the most cost-effective, it is more appropriate to plan to introduce OBD diagnostic equipment and include technological inspection tools in the autonomous management label specifications after tier-5. During the period of the plan, nationwide correlation test of diesel emission testing stations has been finished well, only one inspection line was found to exceed the control range, showing that the quality of testing stations for diesel vehicles is favorable. Finally, the statistics of the past eight years shows that through irregular inspection of diesel vehicles, the country-wide average opacity rate dropped from 0.82m-1 to 0.33m-1, indicating emission by diesel vehicles has improved year by year.
