摘要:
为顺应航运业减排与燃料多元化发展需求，兼顾存量船舶低成本改造，本研究搭建了船用四冲程甲醇/柴油双燃料发动机试验平台，采用进气歧管喷射方式引入甲醇。基于试验测试数据构建了船用双燃料柴油机多性能参数评价体系，并引入灰色决策理论对75%工况下不同甲醇替代率对发动机的动力性能、经济性能与排放性能的影响进行综合评估。试验结果表明：随着甲醇替代率提高，缸压和燃烧强度增加，缸内温度升高，有效燃油消耗率降低，有效热效率和指示功率提升，NOx和碳烟排放分别显著降低和小幅降低，CO排放增加。灰色决策评价结果表明：最佳甲醇替代率为40%。在该替代率下，与原机相比，发动机燃油消耗率降低5.9%，缸压提高0.39 MPa，NOx和碳烟排放分别降低28%和35%，CO排放上升74%。
Abstract:
To address the growing demand for emission reduction and fuel diversification in the shipping industry while considering the low-cost retrofit of existing vessels,a marine four-stroke methanol/diesel dual-fuel engine test platform was established in this study.Methanol was introduced through intake manifold injection.A multi-parameter evaluation system for marine dual-fuel diesel engines was developed based on experimental data.Grey decision-making theory was applied to comprehensively assess the power performance,fuel economy,and emission characteristics of the engine under different methanol substitution rates at 75% load.The results indicate that,with increasing methanol substitution rate,cylinder pressure and combustion intensity increased,in cylinder temperature rose,brake specific fuel comsumption decreased,and both brake thermal efficiency and indicated power improved.Meanwhile,NOx emissions were significantly reduced,soot emissions decreased slightly,whereas CO emissions increased.The grey decision-making results identified the optimal methanol substitution rate as 40%.At this substitution rate,compared with the original diesel-fueled engine,fuel consumption decreased by 5.9%,cylinder pressure increased by 0.39 MPa,and NOx and soot emissions decreased by 28% and 35%,respectively,while CO emissions increased by 74%.
