Abstract

Engine makers are lately interested in the gas engine development as the alternative for diesel engine in order to cope the rise of oil price and the environmental regulation. So, STX has developed the 1.6MW gas engine which was converted from 22HLX diesel engine. The gas engine developed with precombustion chamber, which has good performance of 21bar BMEP at engine speed 1000rpm and low $NO_X$ emission of 50ppm at 15% oxygen composition, has been developed recently. Especially, it has a good thermal efficiency of 45% and a reduction efficiency of green house gas($CO_2$) emission of 25% than a conventional diesel engine.

최근 엔진 메이커들은 원유가 인상 및 대기환경 규제에 대응하기 위하여 디젤엔진의 대안으로서 가스엔진 개발에 대한 관심이 증가되고 있다. 이에 STX는 22HLX 디젤엔진을 기초로 한 1.6MW급 가스엔진을 개발하였다. 예연소실 방식의 개발된 가스엔진은 엔진속도가 1000rpm에서 제동평균유효압력이 21bar이고 질소산화물 배출량이 50ppm(공기 중 산소함유 15% 기준)의 우수한 성능을 가진다. 특히 열효율 45%의 우수한 연료 경제성을 가지며 이산화탄소 배출량은 디젤엔진의 약 75%수준으로 온실가스 저감에도 효과적이다.
