Emission characteristics on regulated pollutants and aldehydes of domestic passenger cars according to the driving modes and fuel types were conducted in this study. In order to compare emission characteristics, test cars with similar manufacturing year and mileage were selected. Also, the driving modes and various fuels were applied to the four driving modes (NIER 5, 9, 12, 14) and three fuel types (diesel, gasoline, LPG), respectively. Regulated pollutant emissions from passenger cars were measured by using chassis dynamometer and emission analyzer. In addition, aldehydes were collected in 2,4-DNPH cartridges using a sampling device in the CVS tunnel and analyzed using ultra high performance liquid chromatography. As a result, it was found that the regulated pollutants of the test vehicles decreased with an increase of the average vehicle speed, while the NOx emission increased at high vehicle speeds. Aldehydes emitted from diesel vehicles were higher than those of gasoline vehicles. In addition, formaldehyde and acetaldehyde accounted for more than 78% of the total aldehydes. In the case of LPG vehicles, acrolein was the highest at around 51-62%. Regulated pollutants and aldehydes emitted from cars are affected by fuel types and displacement and operating conditions. This study is expected to be used as basic data for the estimation of HAPs emissions inventory for mobile source.
