To minimize fuel costs, shipping companies have already been performing slow steaming for their own fleets. Specifically, the slow steaming approach has been adopted for most ocean-going container lines. In addition, because of the increased marine fuel cost that is required to enable increased capacity, there is an urgent need for more advanced fuel-saving technologies. Therefore, in this present study, we propose a fuel-cost reduction method that can improve the performance of diesel engines. We introduce a predetermined amount (0.025% of the amount of fuel used) of fuel additive (oil-soluble calcium-based organometallic compound). For improved experimental accuracy, as the test subjects, we utilize a large two-stroke diesel engine installed in land plants. The loads of the test engine were classified as low, medium, and high (50, 75, and 100%, respectively). We compare the engine performance parameters (power output, fuel consumption rate, p-max, and exhaust temperature) before and after the addition of fuel additives. Our experimental results, confirmed that we can realize fuel-cost savings of at least 2% by adding the fuel additive in low load conditions (50%). Likewise, the maximum combustion pressure was found to have increased. On the other hand, we observed that there was a reduction in the exhaust temperature.

2 시도하였으며, 그결과로중질유의동점도를낮추어가열없이선박용디젤엔진에적용할수있는연구를시행한바있다 [2][3]. 그연구에서는디젤엔진의대체연료로주목받고있는디메틸에테르를혼합하여선박용중질유의동점도를낮추었으며 [2], 디메틸에테르를혼합한중질유의사용으로엔진성능도개선될수있음을확인한연구를보고한바있다 [3]. 또한, 다양한분야에서디젤엔진용연료첨가제에관한많은연구와실증들이이루어지고있다 [4]-[7]. 연료비는선박을운항, 관리하는해운사의예산지출에많은비중을차지하고있으며, 연료비절감을위해서대부분의국내외해운회사에서는선속을다운시켜운항하고있다. 그러나고출력엔진이장착되어있음에도불구하고저부하운전을장시간지속할경우에불완전연소로인한카본생성과고장률증가로정비비용이증가되는문제점이발생되고있다. 또한, 날로증가하는선박의연료비에대한부담은선주에게연료비절감기술개발이절실히요구되고있다. 따라서본연구에서는여러연료비절감방안들중에 T사의연료첨가제 ( 유용성칼슘계유기금속화합물 ) 를선박용중질유에투입함으로써연료비절감을시도하였다. 2. 실험장치및방법 본연구에서는실험의정확도를위해서육상화력발전소에설치된 2행정대형디젤엔진을실험대상으로하였으며, 연료첨가제는사용연료량의 0.025% 비율로투입하면서실험을실시하였다. 실험엔진의부하는배기온도가안정된열적평형을가진후에실험을진행하였으며저, 중및고부하 (50, 75, 100%) 의세단계로나누어서실험을하였고, Limiter로 ±3% 이내로일정하게유지하며, 발전기출력단전압을정격전압으로유지하면서운전하였다. 그리고연료첨가제의투입전과투입후의엔진성능 ( 출력, 연료소비율, 최고연소압력 (P-max), 배기온도 ) 을비교분석하였다.

4 3.1 엔진출력 3. 실험결과및고찰 엔진출력은저, 중및고부하 (50, 75, 100%) 의세단계로나누어서측정하였다. 엔진부하 50% 의저부하에서는 4번측정한평균값을표시하였고, 엔진부하 75% 의중부하와 100% 의고부하에서는 7번측정한평균값을표시하였다. Table 4에서는각각의부하에서출력의증가및감소비율을보여주고있으며, Figure 9는그결과를도표로나타내었다. 50% 의저부하에서는출력이약 2.1% 감소하였으나, 75% 의중부하와 100% 의고부하에서는약 1.6, 0.4% 각각상승하였다. 이러한결과는 75% 부하이상에서첨가제효과로미연분을완전연소함으로써출력이향상되었다고판단된다. 본엔진출력값은측정된출력값을설계 Gen power factor 값으로보정한값이다. 이결과를통해중질유에첨가제를투입하였을경우저부하에서보다는중, 고부하영역에서엔진출력이향상됨을알게되었다.

Table 6: P-max by added fuel (Bar) fuel (Bar) 연료소비율 Table 5와 Figure 10은연료소비율의결과를보여준다. 엔진부하 50% 의저부하에서는 4번측정한평균값을표시하였고, 엔진부하 75와 100% 의중, 고부하에서는 7번측정한평균값을표시하였다. 저부하에서는연료소비율이약 2.2% 감소하였으며, 중, 고부하에서는약 0.7, 0.8% 각각감소하였다. 이러한결과는연소촉진의결과때문이라고판단된다. 즉, 중질유에연료첨가제를투입함으로써전부하에서연비가개선됨을확인하였다. 특히, 중, 고부하영역에서보다는저부하에서연료소비감소율이더높았다.

5 류영현 이영서 남정길 3.4 배기온도 Table 7과 Figure 12는각부하에서엔진의연소후배기온도를보여준다. 각각의값은실린더 12기통을모두측정한후, 평균값을표시하였다. 저부하에서는배기온도가약 2.7% 감소하였으며, 중, 고부하에서는약 2.4, 0.6% 감소하였다. 즉, 중질유에첨가제를투입함으로써전부하에서배기온도가감소함을확인하였다. 이것은중질유에포함된아스팔텐, 슬러지를첨가제에포함된분산제에의해서잘분산시켜연료분사시연료의미립화및균질화효과를가져와안정된연소가될수있도록했다고판단된다.
