As the interest on the air pollution is gradually rising up at home and abroad, automotive and fuel researchers have been working on the exhaust emission reduction from vehicles through a lot of approaches, which consist of new engine design, innovative after-treatment systems, using clean (eco-friendly alternative) fuels and fuel quality improvement. This research has brought forward various main issues : whether PM emissions should be regulated for diesel and gasoline vehicles and whether gasoline and LPG powered vehicles can be further neglected from PM emission inventories. Finally, the greenhouse gas regulation has been discussed including automotive emission regulation. The greenhouse gas and emissions of automotive had many problem that cause of ambient pollution, health effects. Based on various test modes and ambient conditions, this paper discusses the characteristics of LPG on exhaust emissions and greenhouse gases. Also, this paper assessed emission characteristics due to the test temperature. These test temperature were performed by dividing the temperature of the test mode and the lowest local temperature in winter. Through this study, the correlation of vehicle test mode and ambient condition, exhaust emission, greenhouse gas emission was analyzed.

우리가 살아가고 있는 환경을 보호하고 쾌적한 생활을 영위하기 위하여 우리나라도 미국, 일본, 유럽의 일부국가들과 같은 Off-road 차량의 엔진에 대한 규제 입안의 필요성이 대두되게 되었으며, 본 연구는 국내의 건설장비와 농업용 기계에 대한 배출량과 대기오염 기여도를 산출함으로써 향후에 시행될 이들 규제안의 기초 자료를 제공하는데 그 목적이 있다.

As the interest on the air pollution is gradually rising at home and abroad, automotive and fuel researchers have been studied on the exhaust and greenhouse gas emission reduction from vehicles through a lot of approaches, which consist of new engine design, innovative after-treatment systems, using clean (eco-friendly alternative) fuels and fuel quality improvement. This research has brought forward two main issues : exhaust emissions (regulated and non-regulated emissions, PM particle matter) and greenhouse gases of vehicle. Exhaust emissions and greenhouse gases of automotive had many problem such as the cause of ambient pollution, health effects. In order to reduce these emissions, many countries are regulating new exhaust gas test modes. Worldwide harmonized light-duty vehicle test procedure (WLTP) for emission certification has been developed in WP.29 forum in UNECE since 2007. This test procedure was applied to domestic light duty diesel vehicles at the same time as Europe. The air pollutant emissions from light-duty vehicles are regulated by the weight per distance, which the driving cycles can affect the results. Exhaust emissions of vehicle varies substantially based on climate conditions, and driving habits. Extreme outside temperatures tend to increasing the emissions, because more fuel must be used to heat or cool the cabin. Also, high driving speeds increases the emissions because of the energy required to overcome increased drag. Compared with gradual vehicle acceleration, rapid vehicle acceleration increases the emissions. Additional devices (air-conditioner and heater) and road inclines also increases the emissions. In this study, three light-duty vehicles were tested with WLTP, NEDC, and FTP-75, which are used to regulate the emissions of light-duty vehicles, and how much emissions can be affected by different driving cycles. The emissions gas have not shown statistically meaningful difference. The maximum emission gas have been found in low speed phase of WLTP which is mainly caused by cooled engine conditions. The amount of emission gas in cooled engine condition is much different as test vehicles. It means different technical solution requires in this aspect to cope with WLTP driving cycle.

오늘날 자동차에서 배출되는 유해 가스로 인한 지구 온난화를 막기 위하여 많은 환경규제를 받고 있다. 때문에 대부분의 국가들은 출시되는 자동차나 운행 중인 자동차에 대하여 배출가스 검사를 의무적으로 실시하여 배출가스에 의한 대기오염을 줄일 수 있도록 법제화하고 있다. 본 논문에서는 "배출가스 검사/진단시스템" 개발에 대한 고찰을 통하여 배출가스, RPM, 소음을 측정할 수 있는 MCU(micro controller unit) 기반의 데이터 계측기에 대한 설계방안을 제시하고자 한다. 또한, MCU를 기반으로 배출가스(HC, CO, CO2 등) 데이터 확보를 위한 광학 필터처리 기술 및 신호처리 알고리즘을 검토하였다. 자동차의 RPM을 측정할 수 있는 알고리즘에 대한 검토와 배출가스 및 소음을 측정할 수 있는 알고리즘을 개발하여 RS-485, TCP/IP 기반으로 데이터를 전송할 수 있는 배출가스 검사시스템을 제시하고자 한다.
