目前，大约80%的大型船舶使用掩体油（JIS C重油）作为船用柴油机的基础燃料。由于其非常高的运动粘度，这种油被认为是最低等级的化石燃料。因此，需要加热以降低其粘度。本文报道了掺加液化二甲醚改善船用柴油（JIS A重油）燃烧性能的研究。本研究旨在阐明二甲醚-掩体油混合物的有效性。采用毛细管式粘度计对二甲醚和掩体油混合燃料的运动粘度进行了测定。研制了一种含有粘度计的压力传感器，用于在保持二甲醚处于液态的同时测量燃料粘度。从实验中，结果表明，细胞加压导致较小的值的运动粘度，并需要修改，以获得真正的粘度值。结果表明，在323 K时，掺加二甲醚可使掩体油的运动粘度从54%~89%大幅度降低。
Currently, around 80% of large ships use Bunker oil (JIS C heavy oil) as the base fuel in marine diesel engines. With its very high kinematic viscosity, this oil is considered the lowest grade of fossil fuel. Thus, it needs to be heated to reduce its viscosity. The authors have reported that the blending of liquefied DME improved the combustion performance of Marine Diesel Oil (JIS A heavy oil). This study aims to clarify the effectiveness of DME – Bunker oil blends. The kinematic viscosity measurement of DME and Bunker oil blended fuel was performed using a capillary tube type viscometer. A pressure cell which contains the viscometer was developed to measure the fuel viscosity while keeping DME in a liquid state. From experiments, it was shown that the cell pressurization resulted in smaller values of kinematic viscosity, and modification was needed to obtain true viscosity values. It was shown that at 323K, the kinematic viscosity of Bunker oil can be reduced drastically from 54~89% with DME blending.
