Abstract

Many researches on green ship with increasing on economics, efficiency and convenience have been carried out consistently. One of them is development of diesel engines with electronic control. While small duty one for automobiles had been adopted mainly already, disseminating heavy duty one for ships has trouble due to safety and reliability. In order to solve these problem in this study, performance of electronic control and cam type engine installed in parallel on training ship HANBADA of korea maritime university was analyzed and compared. It is certain that specific fuel oil consumption of the electronic control type is lower than cam type and excellent at lower engine load, especially. And the electronic control type shows more effective characteristic at sea trial on specific fuel oil consumption.

선박 운항의 경제성, 효율성 및 편리성을 높이면서 친환경 선박에 대한 연구가 지속적으로 이루어지고 있다. 이 중 하나가 전자제어식 디젤 엔진의 개발이다. 자동차용 소형에서는 이미 전자제어식 디젤기관이 주류를 이루고 있으나 선박에서는 안정성 및 신뢰성의 문제로 보급에 어려움을 겪고 있다. 본 연구에서는 이러한 문제를 해결하기 위하여 전자제어식과 캠식 엔진이 동시에 탑재되어 있는 한국해양대학교의 실습선 한바다호의 주기관을 이용하여 두 엔진의 성능을 비교 분석하였다. 그 결과 전자제어식 디젤엔진의 연료소비율이 저감되었으며 특히 저부하에서의 성능이 보다 우수하였다. 또한 연료소비율에 있어서 해상 시운전에서 훨씬 효과적이었다.
