In addition to a laboratory for the reduction of harmful gas emitted by diesel vehicles, various research studies on real driving conditions have been carried out by the governments of each country. Recently, there have been constant reports of vehicles regarding compliance with exhaust emission regulations for nitrogen oxides and particulate number, both in real driving emissions tests and in-lab certification tests. However, current emission regulations for carbon dioxide from vehicles are being conducted only through in-lab tests aside from a real driving emissions test. Therefore, it is necessary to carry out various research studies on the emission characteristics of carbon dioxide emitted from vehicles in real driving conditions. In this study, a small diesel vehicle was selected in order to carry out real driving tests using the portable emission measurement system(PEMS) on the routes developed by the National Institute of Environment Research(NIER). The data obtained via real driving test was classified by the 5 km/h of vehicle speed section. After a vehicle speed classification, vehicle power and trip duration according to the speed section were calculated in order to obtain vehicle work. This study attempted to predict the real driving CO2 emissions by using vehicle work. Based on the results, the correlation coefficient between the predicted CO2 emissions and the real driving CO2 emissions was observed to be over 0.96, which has proven to be highly reliable. |
