Environmental Protection Administration has been strengthening the emission control over diesel vehicles in order to improve domestic air quality,and developing 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」.And enforcing regulations through the implementation of this project,including new diesel engine and vehicle certification approval、Conformity of Production 、In-Uesd diesel vehicle recall investigation test、durability approval and Conformity of Production,etc.Except for KIA PREGIO vehicle can’t compliance with Conformity of Production and the certificate were abolished,all the other were fitting with regulations. Models for estimating pollution from highway vehicles were studied and their basic methodology was referenced to set up the model for domestic diesel vehicles pollution estimation. The pollution estimation model was developed as a reference tool to evaluate the effectiveness of various diesel vehicle control strategies in the future.
