In order to assist the Environment Protection Administration to negotiate with the Department of Motor Vehicles, the project held 3 consultative conferences separately with the Motor Vehicle Division of Taipei City, Chiayi District and Kaohsiung District. In the conference, experts and scholars were invited to assist in providing answers to questions and coordination on opinions. The project continued the service of replacing gas analyzers with new ones and sending 20 persons to receive their licenses, as well as getting a total of more than 13 million motor vehicle periodic test data from the Motor Vehicle Division’s 2006 and 2007 database for analysis. Since the implementation of OBD requirement for passenger cars from 2008, the project has surveyed domestic garages regarding their capability in testing and repairing cars with OBD. The project simulated malfunction of 5 kinds of pollution control units with 30 times vehicle test to find out the effects on vehicle emissions between MIL with and without immediate repairs. In addition, the project selected 30 cars for Idle, ASM and FTP-75 tests to find out the difference between the tests on pollution reduction and cost effectiveness. The project also proposed a 4-stage plan to phase in OBD inspection system. By holding 2 seminars on motor vehicle emissions inspection, the project has achieved to coordinate local Motor Vehicles Divisions and Environmental Protection Bureaus to negotiate on issues regarding current in-use motor vehicle emission inspection system and phasing in OBD in the future. The project has collected in-use motor vehicle emissions inspection data for analysis and continued the operation and maintenance for the in-use motor vehicle emissions inspection information management system.
