To reduce emissions from gasoline vehicles, the objectives of this project are helping EPA to execute new gasoline vehicle emissions control related four major tasks, which include: implementation new vehicle emissions control measures; continuous upgrade and promote electronic certification application process; draft more stringent emission standards; select and promote low emission green vehicles, and host the award ceremony. As to the implementation of new vehicle emissions control measures: in 2012, there were 414 applications for the new vehicle emissions compliance certificate, 412 certificates were approved and issued covering 305 engine families, of which 90 were comply with the Stage 5 emission standards; to ensure the emissions control quality for sold new vehicles, 1,826 manufacturers’ conducted Conformity of Production testing were audited, and performed 121 new vehicle selective compliance audit tests, the results showed that all test vehicles were comply with the standards; as to the execution of recall and correction investigation program, referred to the sales number of new vehicles’ and their former emission control related information, 50 vehicles covering 10 engine families were selected to perform inspection and exhaust emission tests, the test results showed that all vehicles comply with the standards, but some issues were found include: test engineers were lack of OBD training; load wrong control software for testing; components change period were too short etc.. There were 6,784 imported in-use vehicles, account for 2.2% of total sales, of which 78.6% were imported by importers. The type and number of tests that being performed were as follows: driving cycle tests: 4,941, of which 77.7% by using FTP-75 driving cycle; effective of emissions control system tests: 374; OBD continuous tests: 6,656. As to the task of upgrade and promote electronic certification application process, this project has added new functions such as COP test plan auditing, rejection process adjustment, fool proof capability, automatic process operation; To meet the requirements for new gasoline vehicle certification application and emissions control needs, this project has moved the electronic certification application system to a new location under EPA’s website domain, and performed maintenance periodically to meet EPA requirements on its information system; This project participated the integration mechanism discussion and interface design planning meetings for the establishment of certification system with combined emission and noise certificate application, which could provide manufacturers a convenient environment for the emission and noise certificate application. There are some differences between Taiwan Stage 5 standards and the European Euro 5b standards such as: For the certification driving cycle test, the regulated Particulate Mater (PM) measurement method and limit value are different, and monitoring the catalytic converter exhaust NOx emission and In-Use-Performance-Ratio (IUPR) are not required by the Taiwan Stage 5 OBD standards; The European Euro 6 emission standards will be implemented in 2014, and the regulated CO, THC, NMHC, NOx, and PM limits for the driving cycle testing are the same as the Euro 5b standards but add additional requirement on Particulate Number (PN) limits, initially the value will be set as 6.0 × 10^12 #/km, and may be under adjustment in 2015 or 2016 according to the compliance status of the applications; As to the evaporative emission standards, it was proposed to the European and US regulatory requirements to implement the carry-over and carry-across certifications’ application and approval process; According to the emission test results for the Euro 5 standards certified gasoline vehicles with direct injection engines, the CO, HC, NMHC, NOx, and PM emissions far lower than the Euro 6 standards, but the PN value could only comply with initial Euro 6 standards, unable to meet 6×10^11#/km standard limit. This project has finished collection of vehicle information for the selection of 2012 and 2013 model year low emission green vehicles. The 2012 model year green vehicles were conformed by manufacturers and approved by EPA, which include 4 hybrid electric gasoline vehicles and 12 conventional gasoline vehicles, and the 2012 model year green vehicle related information is currently posted on the EPA green vehicle website for the Public inquiry.
