Recently, 'Clean Diesel' is rising for a countermeasure of high oil prices and global warming. And it accelerates the extension of the passenger car diesel engine market in North America as well as in Europe. We need to contrive the emission of engine for more dynamic driving mode than FTP75 and US06, which are the test cycle of US emission regulation as well as NEDC, which is that of European emission regulation. Existing emission development based on dynamometer by mapping of steady state 14-mode which simulates NEDC, relatively mild driving condition, has limitation because it cannot fully simulate vehicle driving motion. In this research, it is introduced a necessary simulation of vehicle motion, test conditions, test method for developing vehicle emission by using dynamic dynamometer. In addition, the difference of test results is compared and the methods for more accurate simulation are proposed.
