新竹縣政府環境保護局在柴油車污染管制方面，為改善新竹縣之空氣品質，給 予縣民乾淨清新之生活環境，定期委託辦理「柴油車動力計排煙檢測計畫」，期透 過不定期檢驗管制與調修改善，以有效提升新竹縣之空氣品質狀況，達成污染減量 及環境保護之成效。本計畫以稽查行駛於新竹縣之柴油車為主，由民眾檢舉、目視 判煙等方式，通知行駛於轄區內柴油車到站檢測；另以車牌辨識系統稽查行駛於轄 區內自主管理區域之柴油車污染排放情形。 本計畫執行期間，透過動力計檢測(自動到檢、自主管理、通知到檢等)及路邊 攔檢，了解高污染車輛族群，統計分析發現，路邊攔檢不合格率較高，篩選後檢測 117輛次，不合格率為43.6%，其中不透光不合格率以自用大貨車及營業大貨車有較 高之情形，應持續追蹤稽查。相較動力計檢測(到檢共計2,508輛次)，整體不合格率 為4.7%，退驗率為3.0%，其中以車齡18-20年車輛及排氣量2500-3000c.c.的車輛為 不合格率較高族群；以車種來分析，不合格率以營業小貨車較高。應持續寄發不合 格率高之車輛自動到檢通知，以持續掌握污染排放情形。 針對各項到檢專案進行分析，本計畫完成簽署68家企業「環保車隊」，納管 之環保柴油車共計1,441輛，環保車隊整體之不透光率值僅有0.20m-1，相較其他到 檢車輛，污染排放情形最低。簽署自主管理業者796家，納管柴油車3,529輛次，共 核發2,136張自主管理標章，自主管理車輛不透光率數值為0.32m-1，車輛加入自主 管理前、後，不透光率污染改善率達35.4%，顯示環保車隊及自主管理的推動確實 可有效降低車輛污染排放情形。通知到檢車輛(目視判煙、民眾檢舉及不合格複驗) 不合格率較自主管理及自動到檢低， 但整體之不透光率數值僅低於路邊攔檢 (1.60m-1)，不透光率平均值為0.82m-1。 透過目視判煙稽查20,085輛次，寄發目視判煙通知142件；竹竹苗三縣市聯合 稽查；車牌辨識145,327輛次，寄發4,087輛次自動到檢通知等手段，持續管制自主 管理特定區域，促使科學園區納管率達57.2%、內灣風景區達23.7%及新竹工業區 達46.8%。 透過宣導說明會、親訪業者、電話訪查及問卷宣導等作業，已宣導4,194輛次 具補助資格之㇐至三期大型柴油車。申請汰舊補助車輛共計286輛次，補助金額累 摘-II 計至10,029.5萬元。申請濾煙器裝設補助1輛次。申請調修燃油控制系統15輛，補 助金額累計至97.7萬元。並透過CSR環保車隊的推廣，促使簽署業者及其旗下業者 車輛，共計204輛老舊大型柴油車進行報廢汰舊、6輛次裝設環保署認證濾煙器，以 達實質之污染減量。 透過本計畫各項稽查專案之檢測不合格車輛之污染改善、保檢合㇐之車輛事前 調修以及輔導車輛汰除等執行成果，推估污染物排放削減量之改善效益，本計畫推 估粒狀污染物削減37.07噸/年。

Abstract Hsinchu County Environmental Protection Bureau executes the “dynamometer test plan for diesel-fueled vehicle emission” for diesel-fueled vehicle pollution control in order to, on one hand, improve the air quality in Hsinchu County and give citizens their clean air back and, on the other, improve the quality of air in Hsinchu county through inspections and tuning efforts from time to time, as to achieve the effects of pollution reduction and environmental protection. This plan was carried out on diesel-fueled vehicles traveling in Hsinchu County. These vehicles were called to the inspection stations by citizen reports or visual inspection on emission. Also, license plate identification system was deployed to check on the emission of pollutants by diesel-fueled vehicles in the self-management zones in the jurisdiction. Dynamometer testing (reporting to inspection station on drivers own, self-management, inspection by notification) and roadside testing were conducted during the plan to learn more about vehicles of high pollution. The statistics show that the unqualified rate was higher for roadside inspections. 117 vehicles were pulled over for testing and the unqualified rate was 43.6%. The opacity unqualified rate was higher in large private and business trucks, which require further auditing. For the dynamometer testing (2,508 vehicles reported for testing), the general unqualified rate was 4.7% and rejection rate 3.0%; the unqualified rate was higher in vehicles that are 18-20 years old and those with exhaust emission 2500-3000 c.c.; by type of vehicle, the unqualified rate was higher in small business trucks. The notification for inspection will be issued continuously to vehicles of high unqualified rate for better control of pollutant emission. The analysis on individual inspection projects indicates that 68 businesses signed up for “environmental-friendly fleet” with 1,441 environmental-friendly diesel-fueled vehicles included for control. The general opacity of these fleets was merely 0.20m-1, which is the lowest emission of pollutants among all vehicles tested. 796 businesses signed up for self-management and 3,529 diesel-fueled vehicles were included for control. In total, 2,136 self-management labels were issued. The opacity of the vehicles on self-management was 0.32m-1, which was a reduction rate of 35.4% after these vehicles were included for self-management. This indicates the promotion of environmental-friendly fleets and self-management does the job for reducing emission of pollutants from vehicles. Vehicles reporting for testing by notification (visual inspection on emission, reporting by citizens and second tests due to previous failure) exhibited lower unqualified rate than those on self-management and those reporting for testing on their own, but the general opacity was just lower than that of roadside inspection (1.60m-1) with the average opacity of 0.82m-1. For the visual inspection on emission, 20,085 vehicles were identified and 142 notifications issued for visual inspection on emission. Hsinchu City, Hsinchu County and Miaoli County joined force for the inspection efforts. License plate identification was performed on 145,327 vehicles and notification for 􀀡 Abstract-II was issued to 4,087 vehicles to continually manage specific area. The efforts to include specific self-management zones have paid off, as inclusion rate was 57.2% for the Scientific Park, 23.7% for Neiwan Scenic Area and 46.8% for Hsinchu Industrial Park. The efforts of promotional presentations, visits to businesses, telephone interviews and questionnaires have reached 4,194 large Stage I through Stage III diesel-fueled vehicles eligible for subsidies. The application for retirement and replacement subsidy was submitted for 286 vehicles for a total of subsidies of NT$ 100,295,000. A diesel vehicle applied for DPF subsidy. And 15 diesel vehicles applied for subsidies for maintenance of fuel control system for a total subsidy of NT$ 977,000. The promotion of CSR environmental-friendly fleets encouraged local businesses and their vehicles. Therefore, 204 old large dieselfueled vehicles were ready for retirement, and 6 vehicles were installed DPF approved by Environmental Protection Administration for substantial reduction of pollution. This plan has achieved several results, including pollution improvement through detecting nonconforming vehicles, beforehand tuning of vehicles for servicing and inspection in one package, and helping with vehicle retirement and replacement. The improvement of pollutant discharge was estimated. It is estimated that the plan has helped with the reduction of 37.07 ton/year of particulate
