一、前言自1973年石油危机以来,由于原油价格逐年上涨,燃料费在船舶航运费中所占的比例不断增加。在航运业中,燃料费所占的比例甚至超过50%。一般认为,这种涨价的趋势今后必将继续下去。为了应付这种局势,劣质燃料处理装置的研究应用成为目前有关行业最关心的事情,有关研究人员正在尽最大的努力从事这种研究工作。大型柴油机使用低质重油已作为节省燃料费用最有效的方法被广泛地应用。但是在许多作为船用辅机的中小型柴油机中,多数还只能
I. INTRODUCTION Since the oil crisis in 1973, as the price of crude oil has risen year by year, the proportion of fuel costs in the shipping fee of shipping has been steadily increasing. In the shipping industry, the share of fuel costs even exceeds 50%. Generally believed that the trend of price increases will continue in the future. In order to cope with this situation, the research and application of inferior fuel handling devices has become the most concern of the relevant industries at present, and the researchers are doing their utmost to carry out such research work. The use of low quality heavy oil for large diesel engines has been widely used as the most efficient way to save on fuel costs. However, in many small and medium-size diesel engines used as marine auxiliaries, most are only available
