　　本計畫目的為協助環保署執行汽車與機車之新車排放管制相關工作，主要包括執行新車排氣管制業務及研訂排放管制措施二項工作。 　　在新車排氣管制工作方面，新車量產品質一致性管制，廠商計執行3,534輛汽、機車品管測試，並抽驗45家廠商之320輛新車，品管測試與新車抽驗等二項管制測試結果與新車審驗值分布均相近。召回改正調查測試，依據近年排放管制相關資料選取調查測試車輛，完成汽機車20個引擎族100輛的初步調查測試，依各引擎族測試結果平均值判定，汽機車計19個引擎族符合排放標準，機車1個引擎族污染物NOx超過排放標準，於下年度計畫進行確認調查測試。國外進口使用中汽、機車逐車測試計有14,052輛，測試結果多低於排放標準一半以下。 　　在先進國家汽車排氣管制，歐盟於2020年1月執行Euro 6d管制，美國則持續逐年加嚴推動Tier III規定；在機車管制，歐盟自2020年1月實施Euro 5法規，先進國家多同時實施或參考修訂。國內汽機車新車及相關管制規定的修訂，審驗辦法及測試程序均於年度內公告實施，並就法規動及相關管制規定研議，持續與相關廠商溝通與協商。汽機車排放管制措施研究測試，在蒸發排放研究測試，汽車以NEDC與WLTC測試型態各1車次進行48小時日間蒸發測試，NEDC測試型態有較大量的清除量，故HSL測試值較低；機車以有、無裝設活性碳罐各1輛進行1、24、48及72小時日間蒸發測試比較，無碳罐配置機車有較高的蒸發排放。汽車WLTP行車型態排放與實際駕駛排放，完成1車次實驗室比對及實際道路測試，測試結果皆符合相關規範，在環境條件上宜再檢討修訂，以更符合於國內執行。機車OBD行車型態管制門檻值研究測試，完成1輛國內申請歐盟Euro 5認證機車之門檻值測試，廠商已導入符合歐盟規定之引擎控制技術，應可考量推動機車七期OBD Stage II法規引擎點火及含氧感知器失效等二項OBD門檻值測試。

　　The objective of this project is to assist Taiwan EPA on implementation of emissions control tasks relevant to new gasoline passenger cars and new motorcycles, which include carry out new vehicle emissions control tasks and draft emissions control measures. 　　As to the task of implementation of new vehicle emissions control measures: in 2019, there were 807 certificates being issued for passenger cars and motorcycles and most of the certified emission values are distributed below half of their applicable emission standards. As to the task of Conformity of Production (COP) control, the new passenger car and motorcycle manufacturers had performed 3,534 COP tests and the test results were close to their certified emission values and distribution ranges; random selective tests were being performed on 320 new vehicles of 45 manufacturers and most of the test results were distributed below 70% of their certified emission standards. As to the task of individual tests being performed on imported foreign in-use passenger cars and motorcycles, there were 14,052 individual tests being performed and most of the test results were below half of their applicable emission standards. As to the task of recall and correction investigation tests, according to the collected emissions control related information in recent years to select test vehicles and finished the preliminary tests on 100 passenger cars and motorcycles cover 20 engine families. The fail or pass determination of the test results were according to the average test result values for each engine family and there were 19 engine families that comply with their applicable emission standards and the NOx emission of one motorcycle engine family exceed the limit value and will be performed confirmation test during the project of next year. 　　As to the task of collecting and survey advanced foreign country’s emissions control measures, EU will implement its Euro 6d emission standards start from Jan. 2020 and the US will continuously to tighten its Tier III emission standards for passenger cars; as to the motorcycle’s emissions control measures, EU will implement its Euro 5 emission standards start from Jan. 2020 and most of the advanced countries are going to implement the same regulations simultaneously or referred for future amendment setting. As to the task of revision on new vehicle emissions control measures: the certification regulation and test procedures were promulgated in last year; cooperated with the Air Control Act to finish draft regulation revision on the” Management rules on air pollution prevention equipment for mobile sources”, the stakeholders may certify their manufactured air pollution prevention equipment single unit according to the rules; as to the task of retiring high pollution vehicles, this project proposes to adopting subsidies, tax measures, emissions inspection and promotions to facilitate the replacement of old vehicles with new ones. As to the task of research on tightening the gasoline vehicle’s emission standards, this project has completed gasoline vehicle’s 48 hours evaporative emission diurnal tests, for the NEDC driving cycle with larger carbon canister purge capacity, the test results are better than that of WLTP driving cycle and for both of them, the evaporative emission results were far below the standard limits; as to the motorcycle’s 72 hours evaporative emission diurnal tests, for motorcycle that not equipped with carbon canister, its DBL values exceed 2g for 3 consecutive days and were more than 3 times the value compared to motorcycle that equipped with carbon canister. As to the WLTP driving cycle and RDE emissions comparison test for passenger cars, the laboratory and real road driving test results were in compliance with relative guidelines and control standards which means the laboratory are capable to perform the regulatory RDE tests. As to the ambient temperature parameter check, this project suggests to refer methods that being implemented in Japan and being adjusted according to domestic environment conditions. As to the OBD driving cycle emissions threshold research tests for motorcycles, the selected test motorcycles were Euro 5 application certified motorcycles by domestic manufacturers, the results showed that the manufacturers are capable to comply with the EU regulated engine control technologies and able to perform the motorcycle Stage 7, OBD Stage II regulated engine misfire and O2 sensor malfunction two OBD threshold limits tests.
