彰化縣長久以來為工業及農業發展的城市，空氣污染主要來源為各產業型態之工廠及各式機動車輛所排放之廢氣，而隨著都市土地利用型態的改變及民眾環保意識提升，工廠總數逐年減少，但使用中之機動車輛總量卻逐年上升，使得機動車輛所排放之廢氣成為都市空氣污染最主要之來源，因此，如何降低機動車輛之廢氣排放，是本縣當前極重要之環保課題。 目前本縣柴油車設籍數量約6萬4千輛，其中出廠10年以上柴油車約3萬6千輛，本計畫除針對老舊柴油車進行主動通知及宣導，對於使用中柴油車進行路邊稽查、目視判煙稽查及智慧科技稽查等方式加強柴油車黑煙排放管制。同時加強宣導自主管理及保檢合一服務等，以有效管控機車排放空氣污染物情形。 彰化縣柴油車排放污染情形，為瞭解近3年彰化縣柴油車檢驗結果變化善情形，本計畫針對110年~112年柴油車檢驗結果進行不透光率平均濃度分析，其分析結果：站內檢驗不透光率平均濃度0.4m-1降至0.3m-1，站外檢驗不透光率平均濃度則由0.4m-1降至0.2m-1，顯示近幾年透過柴油車自主管理制度以及汰舊換新，確實降低本縣柴油車污染排放。

For an extended period, Changhua County has been dedicated to industrial and agricultural development. The primary contributor to air pollution is emissions from diverse industrial factories and exhaust fumes from various types of motor vehicles. With shifts in urban land usage and a heightened public awareness of the environment, the number of factories has been decreasing annually. However, the total number of operational motor vehicles has been on the rise, establishing emissions from these vehicles as the primary source of urban air pollution. Consequently, mitigating vehicle emissions has become a critical environmental concern in the county. Presently, the county has approximately 64,000 registered diesel vehicles, with around 36,000 exceeding a decade in age. This initiative actively informs and educates owners of aged diesel vehicles, conducting roadside inspections, visual assessments for smoke, and utilizing smart technology inspections to enhance control over black smoke emissions from operational diesel vehicles. Moreover, the promotion of self-management and the integration of inspection and maintenance services are emphasized to efficiently regulate the emission of air pollutants from motorcycles. To comprehend the pollution scenario from diesel vehicles in Changhua County over the past three years, this initiative analyzes the average opacity concentration of diesel vehicle inspection results from 2021 to 2023. The analysis reveals a decrease in the average opacity concentration within inspection stations from 0.4m-1 to 0.3m-1, and outside inspection stations, it has reduced from 0.4m-1 to 0.2m-1. This suggests a decline in diesel vehicle pollution emissions in the county through the implementation of self-management systems and the gradual phase-out of older vehicles.
