| 为助力船舶低碳转型以及为生物燃料油在航运领域的规模化应用提供科学依据，以大型船用低速柴油发动机为研究对象，选取柴油发动机推进特性下的5个典型工况负荷点（25%、50%、75%、90%、100%），以船用燃料油180重油为对照，考察掺混不同比例（15%、24%、30%、50%）生物柴油生物燃料油的燃烧特性、动力性能及排放特性。结果表明：与180重油相比，生物燃料油的比燃油消耗量轻微增加，并随着生物柴油掺混比例的增加略有上升，但压缩压力与峰值燃烧压力与180重油相近，表明其动力性能相当；低负荷时生物燃料油排气温度无明显变化，高负荷时虽略有升高但未影响功率输出；生物燃料油的着火提前角大于180重油的，并随着负荷的增加，着火提前角降低；在同一负荷下，使用5种燃料油时气缸压力差异很小；生物燃料油放热率受生物柴油掺混比例和负荷的影响，其中掺混比例24%时燃烧速率最快；生物燃料油的废气质量流量与180重油接近，CO2排放因子低于180重油，虽然4种生物燃料油的NOx排放因子有所增加，但均满足IMO的排放要求。综上，生物燃料油可部分替代传统船用燃料油。 |

| To facilitate the low-carbon transformation of ships and provide scientific basis for the large-scale application of biodiesel blend in the shipping industry, with a large marine low-speed diesel engine as the research object, five typical load points (25%, 50%, 75%, 90% and 100%) under the propulsion characteristics of diesel engines were selected. The 180 CST marine fuel oil was used as the control, and the effects of blending different proportions (15%, 24%, 30% and 50%) of biodiesel on combustion characteristics, power performance and emission characteristics were investigated. The results showed that compared with 180 CST marine fuel oil, the specific fuel consumption of biodiesel blend slightly increased and rised slightly with the increase of blending ratio, but the compression pressure and peak combustion pressure were similar to those of 180 CST marine fuel oil, indicating that the power performance was comparable. At low loads, the exhaust temperature of biodiesel blend did not change significantly, and although it increased slightly at high loads, it did not affect the power output. The ignition advance angle of biodiesel blend was greater than that of 180 CST marine fuel oil, and decreased with the increase of load. At the same loads, the cylinder pressure differences among the five types of fuel were very small. The heat release rate of biodiesel blend was affected by the blending ratio and load, and the combustion rate was the fastest when the blending ratio was 24%. The exhaust gas mass flow rate of biodiesel blend was close to that of 180 CST marine fuel oil, and the CO2 emission factor was lower than that of 180 CST marine fuel oil. Although the NOx emission factor increased, all four types of biodiesel blend met the usage requirements of the IMO. In conclusion, biodiesel can partially replace traditional marine fuel. |
