摘　　要：针对绞吸挖泥船柴油机在香港国际机场第三跑道3206标段回填工程中排放性能不达标的问题,对“天滨”绞吸挖泥船的16V240ZC型柴油机排放问题进行分析,重新匹配增压器,改造冷却水系统,增加VTG(增压器可变喷嘴)电子控制系统,并进行实船应用。结果表明,改善后的柴油机的空燃比得以优化,燃烧效率提高,油耗降低3%,烟度值FSN从0.61下降到0.40以下,改善了排放性能。In the backfill engineering of the 3206 block of the third runway of Hong Kong international airport,the discharge performance of the cutter suction dredger’[KG-*3]s diesel engine is substandard.Based on the analysis of the 16V240ZC diesel engine of cutter suction dredger“Tianbin”,we rematch the supercharger,renovate the the cooling water system,install the variable turbocharger geometry(VTG)electronic control system,and implement the real ship application.The results show that the air-fuel ratio of the improved diesel engine is optimized,the combustion efficiency is improved,the fuel consumption is reduced by 3%,the smoke value FSN decreases from 0.61 to 0.40,and the emission performance is improved.
