Abstract
We proposed a method to convert the CO2 emission data of vehicles collected from the chassis dynamometer test from distance unit to energy unit which generally measured from the engine dynamometer tests. In the future, if engine dynamometer tests are limited, it is expected to be applied as an alternative method to calculate CO2 emission based on energy unit through the chassis dynamometer test. At this moment, engine efficiency is required and the test mode average efficiency should be used to improve the accuracy, not the result derived from specific speed and load conditions. Also, this method was applied to foreign data and the results were within 0.2%. However, CO, NOx and THC which have very low emission characteristics except CO2, are limited by the method proposed in this study and need to be considered separatively.
