本文主要阐述自1973年石油危机以来的十多年中,各主要船用柴油机生产厂,如 M.A.N.Sulzer B&W Mak 等为提高船用柴油机的有效效率,减小单位功率的比油耗率;为配合螺旋桨发挥其最佳推进效率以降低慢速柴油机转速而发展的超长行程慢速柴油机;为降低船用柴油机的营运成本使用重油的研究,包括对四冲程小功率;中高速柴油机的燃烧重油;为降低生产成本降低比油耗率对中高速柴油机提高其单缸功率,为提高柴油机装置的效率,如何利用废气、废水中的余热,供船舶燃、润油的预热,生产蒸汽,发电以及提供螺旋桨推进辅助功率等的发展工作情况及其成果与展望。
This article mainly elaborates that for more than a decade since the oil crisis in 1973, major marine diesel engine manufacturers such as MANSulzer B & W Mak have been trying their best to increase the effective efficiency of marine diesel engines and reduce the specific fuel consumption per unit of power. Long-run, slow-running diesel engines with the best propulsion efficiency for slowing down the speed of diesel engines; Research on heavy oil use to reduce the operating costs of marine diesel engines, including low-power for four-stroke engines; High-speed diesel engines for heavy fuel oil burning; Reduce the ratio of fuel consumption on the high-speed diesel engine to improve its single-cylinder power, in order to improve the efficiency of diesel engine installations, how to use exhaust gas, waste heat in waste water, for ship combustion, oil preheating, steam production, power generation and propeller propulsion auxiliary power Etc. and its achievements and prospects.
