在台灣地區除台北地區已建制完成捷運系統之外, 絕大部分都市仍以柴油車輛做為最主要的大眾運輸工具，由於國內經濟快速進步，機動車輛數快速成長，成為最主要的移動性空氣污染源。而柴油引擎具有高扭力低故障之特性, 柴油車輛長久以來一直是客﹑貨運業者之主要選擇。嘉義市目前有柴油車大客車435輛和大貨車2742輛，及汽、柴油小貨車有7717輛及特種車826輛，為了解使用中車輛之排煙情形並促使排放黑煙的柴油車主即時進行污染改善，本計畫利用建立完成之動力計排煙檢測設備, 對設籍本市有排煙過量之虞之柴油車輛進行排煙檢測, 並對於柴油車使用之燃油進行含硫量分析，期以降低嘉義地區柴油車排氣污染量。 本年度到站檢測車輛數共有1259輛次，檢驗不合格率為4.8 ％。 如再將自提污染改善申請到檢車輛與被動收到通知到站檢測車輛分別評估，則通知到檢車輛之不合格比例〈2.9％〉比自提改善車輛之不合格率〈1.9％〉高出53％之多。本年度亦執行500輛次之路邊攔車排煙檢測。不合格率高達29.8％為通知到檢不合格率的10.3倍。對於柴油車輛使用油品含硫量之檢測結果，使用含硫量過高之不合格油品約佔10％。本計劃排煙檢驗不合格，經過檢修調整維護引擎後經複驗合格有56輛。推估本計劃執行成效每年約可減少PM10排放量3.32公噸，約為嘉義市柴油車排煙粒狀污染物總排放量之1.47 ％。

Excluding the Taipei area, there is no convenient public transportation system established in most metropolitan areas of Taiwan. This made diesel powered vehicles are still the major tool for both human and cargo transportation. Diesel engine has benefits for its high torque、low maintenance cost, and better fuel economy than its comparable gasoline engine. These made diesel vehicles as one of the first choice for on-road transportation. There are 435 and 2742 vehicles for heavy-duty passenger cars, and heavy-duty trucks, respectively, in Chia-Yi city. Combining with 8543 light-duty diesel vehicles, these made the major particulate emitting source for the city. In this project, the on-road diesel vehicles are monitored. Vehicles which show abnormal emission status were recalled for smoke emission test using chassis dynamometer run on both CNS-11644 free acceleration test, and CNS-11645 full load smoke emission tests. Diesel fuels, which sampled from the smoke test vehicles, were inspected for there sulfur content. It was found that, there were 60 vehicles out from 1259 tested vehicles emitted higher smoke than the regulated levels. This made an unqualified rate of 4.8%. Having I & M practice, there were 56 vehicles pass from the smoke re-tests. It was estimated, there would be a 3.32 tons of particulate matter reducing per year, which equal to 1.47% of the total PM10 emission in Chia-Yi city, because of the performing of this project. Fuel sulfur inspection results showed that there were 10% of the tested vehicles using unqualified diesel fuels, this made a much worse particulate emissions.
