초록

국내 외에서 대기오염에 대한 관심이 점점 증가함에 따라 자동차 및 연료관련 분야의 연구자들은 새로운 엔진설계, 향상된 후처리장치, 청정연료 그리고 연료품질향상을 통해 자동차의 배출가스 감소를 위하여 지속적으로 노력해 왔다. 따라서, 본 연구에서는 자동차의 증발가스와 성능, 환경성에 대해 살펴보고자 하였으며, 연료의 옥탄가 향상제로 쓰이는 바이오 에탄올, 바이오 부탄올, 바이오 ETBE (Ethyl Tertia ry Butyl Ether), MTBE (Methyl Tertiary Butyl Ether)가 환경에 미치는 문제점에 대해 살펴보고자 하였다. 주로 휘발유의 옥탄가 향상제로 쓰이는 바이오 에탄올, 바이오 부탄올, 바이오 ETBE, MTBE가 휘발유 연료 특성 중 증발가스에 미치는 영향에 대해 살펴보았으며, 바이오 연료 특성에 대한 가솔린 자동차의 가속 및 동력 성능을 살펴보았다. 실험결과 증발가스는 최대 1.04g/test로 모든 시험 연료가 국내 배출가스 기준에 부합함을 알 수 있었으며, 원료에 대한 증기압 측정 결과 바이오에탄올 15kPa, 바이오 부탄올 1.6k Pa로 E3급 연료 제조 시 바이오 부탄올 함유량을 늘리면 증기압과 증발가스 또한 낮게 나타났다. 또한, 바이오 연료의 종류에 따라 유사한 가속 및 동력 성능을 나타내었으며, 바이오 부탄올과 바이오 에탄올 비교시 가속 성능이 약 3.9%, 출력은 0.8% 개선되었다.

As the interest on the air-pollution is gradually rising up at home and abroad, automotiv e 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 three main issues : evaporative, performance, air pollution. In addition, researcher studied the environment problems of the bio-ethanol, bio-butanol, bio-ETBE (Ethyl Tertiary Butyl Ether), MTBE (Methyl Tert iary Butyl Ether) fuel contained in the fuel as octane number improver. The researchers have many dat a about the health effects of ingestion of octane number improver. However, the data support the con clusion that octane number improver is a potential human carcinogen at high doses. Based on the bio-fuel and octane number improver types (bio-ethanol, bio-butanol, bio-ETBE, MTBE), this paper dis cussed the influence of gasoline fuel properties on the evaporative emission characteristics. Also, this p aper assessed the acceleration and power performance of gasoline vehicle for the bio-fuel property. As a result of the experiment, it was found that all the test fuels meet the domestic exhaust gas standards, and as a result of measurement of the vapor pressure of the test fuels, the bio - ethanol : 15 kPa and the biobutanol : 1.6 kPa. thus when manufacturing E3 fuel, Increasing the biobutanol content reduces evaporation gas and vapor pressure. In addition, Similar accelerating and powering performance was shown for the type of biofuel and when bio-butanol and bio-ethanol were compared accelerated perf ormance was improved by about 3.9% and vehicle power by 0.8%.
