The main objective of this project is to assist EPA to implement new gasoline vehicle emissions control related tasks, the three major tasks were: implementation of new vehicle emissions control measures; continuous promoting the electronic certification process; draft more stringent emissions standards. Implementation of these tasks could control and reduce emissions from gasoline vehicles. In 2015, 367,600 new gasoline vehicles were applied for certifications, 97% of them using new vehicle type approval and the other 3% of imported in-use vehicles using individual tests for the certification process. This year 387 new gasoline vehicle emission certificates were issued most of them adopted the EU NEDC driving cycle tests for certification, major distribution of emissions values were below half of the standards limit values; 2,268 Conformity of Production tests were performed by manufacturers and audited by this project, 119 new gasoline vehicle random selection compliance tests were performed and results and distributions were close to that of certification values; as to the recall and correction investigation tasks, according to the related emissions information to select 2011~2012 model year gasoline vehicles in 10 engine families to perform verification tests, the test results showed that all test vehicles were in compliance; as to the green vehicle evaluations, new vehicle’s environmental information were periodically updated and provided as reference for the Public to purchase eco-friendly gasoline vehicles; as to the foreign in-use gasoline vehicles tests, 7,797 vehicles adopted driving cycle tests and 97% of them were using FTP-75 driving cycle for the test and the results showed that most of them were below half of the standards limit values. As to the electronic certification process functionality improvement s, in addition to meet the policy and certification implementation related requirements, maintenance, review and revision of the certification system’s functionalities also being performed and the capability of multi-browser website certification system and green vehicle guide modification and revision also being added and completed its functionality validations. As to the implementation of vehicle emissions control measures, related emissions systems were established to provide shared information of CO2 emissions for green vehicle evaluation and domestic made vehicle fuel economy compliance certification needs. In the future, may consider including sharing functionality of vehicle fuel economy test results in the emissions test reports database and certification management system to facilitate relevant operational management needs. EU will implement its Euro 6c emissions standards and start from the same year, the US EPA’s Tier 3 emissions standards will be phase in year by year. To harmonize the gasoline vehicle emissions standards with the advanced countries, this project proposed to implement the domestic gasoline vehicle’s Stage 6 emissions standards since Sep. 1, 2019. The main contents of Stage 6 standards are referred to the EU Euro 6c and the US Tier2 Bin5 emissions standards; As to the OBD IUPR verification research on new production vehicles and in-use vehicles, most of the vehicles were affected by the regulations in advanced countries, their OBD device already in compliance with the OBD IUPR requirements. Two OBD IUPR regulation compliance OBD families were selected to perform separately 12 validation tests and the results showed that all of them were comply with EU OBD Euro 6-1 stipulation; This project proposed to implement OBD IUPR measures by referring to OBD Euro 6-2 provisions, and accept the manufacturer’s claiming during new vehicle type approval stage, and request manufacturers to provide in-use vehicles’ inspection, maintenance and OBD information to the authority to be reviewed. If the authority has any concerns, the following investigation tests will be performed to ensure the monitoring functionality of the vehicle’s OBD device.
