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." The project in past year has completed several targets to enforce the regulations, in which including 328 approval licenses released to new diesel engines and vehicles, a random inspection to brand new car from 18 automakers, and 10 in-used diesel vehicles confirmed tests, …etc. All inspected products mentioned above have met emission standards, except the one from a Ford distributor in Taiwan did not pass the criterion from preliminary testing. ARTC has not only mediated and submitted the updated regulation to criterions and methods in terms of complying with international emission controlled trend, but transferred the certification system into electric operation completely in order to ensure the proceeding effectively. In addition, we have analyzed emission level and control strategies on both PM2.5 and CO2 pollutants from diesel vehicles, and drafted OBD relevant restraint methods applied in Taiwan. Therefore, those achievements will be the bases of ruling next emission strategy to various diesel vehicles.
