Comparison Study of Certification Emission Test and Real-time Road Driving Emission Test for Various Emission Level Vehicles

摘要

Vehicle driving test has been conducted on a chassis dynamometer with NEDC mode for diesel vehicles and CVS-75 for gasoline vehicles. And also excessive driving test has been done with US06 for rapid acceleration and high speed driving and SC03 for maximum load operation condition for air-conditioning. The test has been carried out on 22 vehicles having different emission levels from EURO-4 to SULEV in order to understand emission characteristics clearly. This research aims to investigate characteristics of NOx and PM emissions in driving conditions as emission standard has been strengthened and furthermore to provide political plans for the improvement of air-pollution in near future.
