Abstract

The automotive exhaust gases generated by the vehicles containing carbon monoxide, hydrocarbons and lead, is a large concern because of their harm to human health or the living environment. To reduce exhaust gas, it is important to develop a variety of techniques that are currently being used by elemental analysis to determine the optimal conditions. In this study, the anti-freeze coolant contained in the exhaust gas was examined, which can affect the emissions. The effects of the commercially available coolant from five domestic companies on the HC, NOx and $CO_2$ emissions were analyzed to determine the optimal amount of antifreeze. In addition, antifreeze products from the five companies were analyzed with respect to driving time of the cooling fan and the correlation of the NOx emission analysis. The temperature of the engine oil was matched using a manual gear of small passenger inspection standard speed $40{\pm}2Km/h$ so the vehicle could meet the specifications for inspection $90{\sim}93^{\circ}C$. The Company D fan operation time resulted in the shortest antifreeze, $CO_2$ and NOx emissions.

자동차 배출가스는 자동차에 의해 발생되는 일산화탄소, 탄화수소, 납 외에 사람의 건강 또는 생활 환경에 피해를 일으킬 염려가 있는 물질을 말한다. 배출가스를 감소시키기 위해서 다양한 기술을 개발하는 것도 중요하지만 현재 사용되어 지고 있는 요소를 분석하여 최적의 상태를 찾는 것도 중요한 사항이라 여겨진다. 본 연구는 냉각수에 함유되는 부동액이 배출가스에 영향을 미칠 수 있음에 착안하여 현재 국내에서 시판되고 있는 5개 회사제품의 부동액을 권고 수준의 양을 냉각수에 함유시켜 HC, NOx, $CO_2$ 배출량을 측정하고 배출가스에 미치는 영향을 파악하고자 하였다. 또한, 5개회사 부동액 제품에 대하여 냉각팬 구동시간과 NOx 배출량과의 상관관계를 살펴보고자 하였다. 엔진오일의 온도는 자동차 검사 규격에 맞도록 $90{\sim}93^{\circ}C$에 맞추었고, 수동기어를 사용하는 소형승용차의 검사 규격 속도 $40{\pm}2Km/h$에서 수행하였다. 실험결과 D사 부동액이 팬 작동시간이 가장 짧고, $CO_2$, NOx 배출량이 가장 적게 나타났다.
