Chassis dynamometer testing in connection with high-resolution FTIR spectroscopy was used to measure exhaust emissions of nitrous oxide(N₂O) from a in-use fleet of 20 passenger cars. Exhaust emissions were collected for KIER city and KIER highway driving mode. In-use vehicles investigated, including LPG powered passenger cars, were recruited for various emissions testing requirements during 1999 and 2007. A high correlation between N₂O and nitrogen oxides was observed.

Chassis dynamometer testing in connection with high-resolution FTIR spectroscopy was used to measure the non-regulated emissions such as methane(CH₄), nitrous oxide(N₂O) and ammonia(NH₃) as well as the regulated emissions such as carbon monoxide(CO), total hydrocarbon(THC) and nitrogen oxides(NOx). A LPLi type passenger car and a LPGi type passenger car were used. As C3 content of LPG fuel increases, CO and THC emissions were decreased but NOx was increased in LPLi passenger car. In a LPGi type passenger car, however, the opposite trend was observed in exhaust emissions.

Bio diesel is one of the clean alternative fuels, and is known to produce less air pollutants than petroleum-based diesel. Bio diesel blended with petroleum diesel can be used. In this paper, exhaust emissions were investigated at various bio diesel mixing rations. Chassis dynamometer testing in connection with high-resolution FTIR spectroscopy was used to measure exhaust emissions including formaldehyde(HCHO) and greenhouse gases such as nitrous oxide(N₂O) and methane(CH₄). Exhaust emissions were collected for CVS-75 driving mode. The results showed that THC and PM decreased but CO, NOx, CH₄, N₂O and HCHO increased gradually, as the mixing ratio increases.

RSD (Remote Sensing Device), which is a roadside measuring device, can measure the exhaust emissions from the vehicle to pass the RSD device without any interference. RSD is capable of measuring the CO, HC, NO, CO₂ emissions from on-road vehicle within 1 second. Therefore, it can provide thousands of on-road emissions data in a day. In the present study, RSD was used to measure the exhaust emissions from the gasoline and LPG vehicles on the 27 test sites in Seoul metropolitan areas. Totally 177,849 of effective data were obtained during 104 days, and these data were used to analyze the average CO, HC and NO emissions by vehicle model year, and also to analyze the cumulative distribution by the concentration of exhaust emission for the reference to identify the low and gross emitters.

Mixed waste plastic, which cannot be recycled, becomes solid waste fuel (SRF, Solid Refuse Fuel) and is incinerated at waste-to-energy facilities and used for steam production and power generation. Mixed waste plastic is composed of thennoplastic and thermosetting plastic. In this study, we are developing synthesis gas production system through mixed waste plastic gasification and hydrogen production technology based on synthesis gas. In addition, the goal is to develop a high-temperature swirling melt gasification reactor system of over 1200°C, which is higher than the general gasification temperature, and to melt and slag the residue and discharge it. We would like to introduce some of the operating characteristics and experimental results of the high-temperature gasification reactor in this study.
