中、低速机的燃油经济性与有效负载中速柴油机有哪些方面符合要求高、选择余地少的主推进机械的设计要求?两台直列9缸TM620柴油机提供32,000轴马力的动力。动力装置的的选用取决于燃油消耗率与空间两种因素的平衡。当直接比较燃油消耗率时,低速柴油机占有优势。大型低速柴油机的实用最低燃油消耗率比最经济的中速机还要低,但小 Medium and low-speed fuel economy and payload medium-speed diesel engine which meet the requirements of high, less choice of main propulsion machinery design requirements? Two inline 9-cylinder TM620 diesel engine to provide 32,000-horsepower. Power plant selection depends on the fuel consumption and space balance of two factors. When comparing fuel consumption directly, low-speed diesels have an advantage. The practical minimum fuel consumption of a large low-speed diesel engine is lower than the most economical medium-speed engine, but small
