一、前言近几年来,石油涨价了,这对船舶航运的经济性有很大的影响,从而对节省能源问题提出了更高的要求。针对这种情况,日本洋马公司很快投入了研制低燃油消耗率、使用低质重油柴油机的工作。一九七七年以后,该公司研制成了S185柴油机[缸径×行程=180×230(毫米)]和T220柴油机[缸径×行程=220×280(毫米)],这两种机型均以燃油消耗率低而驰名。T260柴油机是其系列的一种,是该公司汇总了多年来积累的技术成就和研究成果研制而成 I. Introduction In recent years, the price of oil has risen, which has a great impact on the economy of shipping and shipping, thus putting forward higher requirements on the issue of energy conservation. In response to this situation, Yanmar Japan was quickly put into the development of low fuel consumption, the use of low-quality heavy-duty diesel engine work. After 1977, the company developed the S185 diesel engine [bore × stroke = 180 × 230 mm] and T220 diesel engine [bore × stroke = 220 × 280 (mm)], both of which are powered by fuel Low consumption and well-known. T260 diesel engine is a series of its kind, is the company has accumulated over the years accumulated technical achievements and research results developed
