Abstract

The main engine of a vehicle is used an common rail diesel engine for improving the efficiency of the whole load area. However, the generator engines is still used mechanical fuel injection valve drive cams. In addition, most of generator engines is applied a part-load operation of less than 50%. Therefore, diesel engine of vehicle set at 100% load is necessary to readjust in order to perform efficient operation because of part-load operation. In this study, the objective is to report the results of the part-load fuel consumption improvement by injection timing readjust to identify the operational characteristics of a generator engine currently operated in the facilities.

차량에 사용되는 주엔진은 부하영역 전체에서 효율을 증가시키기 위해 커먼레일 디젤엔진을 사용하고 있다. 그러나, 발전기용 엔진은 아직도 기계적 구성엔진으로 캠으로 구동되는 연료분사밸브가 사용되어지고 있다. 또한, 발전기용 엔진 대부분은 50%이하의 부분부하가 적용되고 있다. 따라서, 전부하에 세팅된 차량용 디젤엔진을 부분부하에서 효율적인 운전을 하기 위해서는 연료분사시기 재조정이 필요하다. 본 연구에서는 시설물에 사용되는 엔진발전기의 운용특성을 파악하여 연료분사시기를 재조정함으로서 부분부하 연료소비율을 개선시킨 결과를 연구하고자 한다.
