Abstract

Automatic transmission fluid (ATF) is used for automatic transmissions in the vehicle as the characterized fluid. Recently, the vehicle manufacture usually guarantee for fluid change over 80000~100000 km mileage or no exchange, but most drivers usually change ATF below every 50000 km driving in Republic of Korea. It can cause to raise environmental contamination by used ATF and increase the cost of driving by frequently ATF change. In this study, we investigate the various physical properties such as flash point, fire point, pour point, kinematic viscosity, cold cranking simulator, total acid number, and metal component concentration for fresh and used ATF after driving (50000 km, 100000 km). The result showed that the total acid number, pour point, Fe, Al and Cu component had increased than fresh ATF, but 2 kind of used oil (50000 km and 100000km) had similar physical values and metal component concentration.

자동변속기유는 자동차의 자동변속기의 성능을 유지시키기 위해 사용되는 유체이다. 최근 자동차 제조사에서는 일반적으로 자동변속기유를 80000~100000 km 주행후 교환 또는 무교환을 보증하고 있지만 국내에서는 많은 운전자들이 50000 km 이하에서도 자동변속기유를 교환하고 있는 것으로 조사되었다. 빈번한 자동변속기유의 교환은 환경오염과 차량유지비용을 상승시키는 원인으로 작용되고 있다. 본 연구에서는 사용하지 않은 신유와 50000 km와 100000 km를 각각 주행한 뒤 회수된 자동변속기유를 대상으로 인화점, 연소점, 유동점, 동점도, 저온겉보기점도, 전산가, 금속분과 같은 물리적 특성을 분석하였다. 연구결과, 신유에 비해 사용유는 전산가, 유동점, 금속분이 증가되는 것을 확인하였지만, 두 종류의 사용유(50000 km, 100000 km)의 물리적 특성과 금속분 함량의 차이는 크지 않음을 알수 있었다.
