三峡库区船舶最佳航速与柴油机能耗和排放变化分析

Analysis of optimum speed and variation of diesel engine energy consumption and engine exhaust of the Three Gorge reservoir ship

三峡库区船舶节能增效是船舶航行与管理面临的主要问题。文章通过分析船舶柴油机运行机理与船舶操纵航行条件,提出了三峡库区船舶以最佳航速运行是船舶柴油机动力装置节能和船舶驾驶操纵的最佳方式,也是库区船舶节能的有效方法。船舶在最佳航速下运行,适当调整柴油机主要参数,以使柴油机在最佳航速下其工况接近于柴油机额定工况,保证柴油机动力性、经济性和排放污染物得到提高和控制,真正实现船舶节能增效。

The main problem of ship operation and management for ships operation in Three Gorge area is energy saving and increasing of economic benefit. This paper discusses and presents that running at optimum speed is the best manner and method for energy saving, ship-handling and marine engine management for such ships. Energy saving and improving of economic eficincy can be realized by adjusting the major parameters of the diesel engine when the ship is running at optimum speed to let the diesel engine running at the condition close to rated condition, so as to ensure best control and increasing of engine power performance, economic performance and exhaust discharge.
