In order to improve domestic air quality, the Environmental Protection Administration in Taiwan has strengthened the emission control over diesel vehicles and developed comprehensive regulations, such as "The Procedure of Rebelling and Abolishing the Certificate of Emission Inspection for the Types of Diesel and other Alternative Fuel Engine Vehicles." This project completed several targets to enforce the regulations, including 376 cases of new diesel engine and vehicle certification approval, conformity of production for 18 vehicle manufaturers, and 2 vehicle models (5 vehicles for each model ) of in-used diesel vehicle confirm investigation tests, etc. For domestic and international situations, such as the trend of complying with the regulation and mediating, this plan revised the relevant rules and regulations timely. The electronic operating system is build to execute compliance certification of emission inspection for diesel vehicles, which can make the administrative procedures more effectively. In addition, we analyzed emission level and control strategies of pollutants in diesel vehicles, and drafted Portable Emission Measurement systems (PEMS) relevant restraint methods applying to our country. Those will be bases to evaluate the effects of various diesel vehicle control strategies in the future.
