Abstract

Concern about air pollution is gradually rising up in domestic and foreign, automotive and fuel researchers are trying to reduce vehicle exhaust emissions, through a lot of approaches, which consist of new engine design and innovative after-treatment systems, using clean (eco-friendly alternative) fuels and fuel quality improvement. This research is proceeding by two main issues : exhaust emissions and PM particle emissions of gasoline vehicle. Exhaust emissions, non-regulated emissions and PM (particulate matter) particles of automotive are causing many problems which ambient pollution and harmful effects on the human body. The main particulate fraction of automotive exhaust emissions consists of small particles. Because of their small size, inhaled particles can easily penetrate deep into the lungs. The rough surfaces of these particles make it easier for them to combine with other toxins in the environment. Thus, the hazards of particle inhalation are increased. Based on the oxygenated fuel additive types (MTBE, Bio-ETBE, Bio-ethanol, Bio-butanol), this paper discussed the influence of oxygen contents on gasoline vehicle exhaust emissions, non-regulated emissions and nano-particle emissions. Also, this paper assessed exhaust emission characteristics at 2 type test modes. The test modes were FTP-75 and HWFET. All measurement items be verified less than the value of regulated emissions. It could be known difference increase and decrease by each measurement item depending on increase the oxygen contents.

대기오염에 관한 관심은 국내 외에서 점진적으로 상승하고 있으며, 자동차와 연료분야 연구자들은 청정 (친환경 대체연료) 연료와 연료품질 향상 등을 이용하여 새로운 엔진 설계, 혁신적인 후 처리 시스템 등의 많은 방법으로 차량 배기가스를 감소시키려고 노력하고 있다. 이러한 연구들은 주로 배출 가스 및 가솔린 차량의 PM 입자 배출 두 가지 이슈로 진행되고 있다. 자동차의 배출가스 및 미규제 물질, PM (입자상 물질) 입자는 환경오염과 인체에 악영향을 주는 많은 문제를 일으키고 있다. 자동차 배출가스의 주요 물질인 입자상 물질은 작은 입자로 구성된다. 이러한 작은 크기 때문에, 흡입된 입자는 쉽게 폐 깊숙이 침투 할 수 있다. 이 입자의 거친 표면들은 대기중에서 다른 독성 물질과 결합하기가 쉽다. 따라서 입자흡입의 위험을 증가시킨다. 함산소 연료첨가제 유형 (MTBE, 바이오 ETBE, 바이오 에탄올, 바이오 부탄올)에 기초하여, 본 논문은 가솔린 자동차 배출가스 및 미규제 물질, 나노입자 배출에 산소함량의 영향을 토론하였다. 또한, 본 논문은 두 가지 시험모드를 사용하여 배출가스 특성을 평가하였다. 시험모드는 FTP-75 및 HWFET 모드이었다. 전체 측정항목에서 배출가스 규제 값보다 적게 배출되고 있는 것을 볼 수 있었고, 산소함량이 증가하면서 측정항목에 따라 증감이 다름을 알 수 있었다.
