摘要

采用水乳化燃料的船用柴油机在“日本丸”号训练舰发电机柴油机厂运行。这次实际操作共运行了2063小时。但在实际运行中,出现了对电力负荷的快速增加缺乏响应性能和燃油喷射系统泄漏乳化燃油处理困难等问题。进一步研究了柴油机大修时乳化燃料对各组成部件的影响,得出以下结论:1)在使用乳化燃料的情况下,与船用柴油相比,喷射阀的开启压力总是降低。2)喷油嘴和泵柱塞有轻微的异常磨损。3)活塞群上有玻璃状的白色沉积物和褶皱痕迹,这是由于乳化燃料中含有水分造成的。

Study on the Operational Results of a Marine Diesel Engine Using Water Emulsified Fuel from the Marine Engineer's Aspect
The marine diesel engine using water emulsified fuel was operated in a diesel engine plant for the electric generator on Training Ship “Nippon Maru”.This practical operation was carried out 2, 063 hours of total running.However several problems such as the lack of response performance to rapid increase of electricload and difficulty in disposal of leaked emulsified fuel from fuel injection system, occured in this operation.Further more the influence of emulsified fuel to the constituent parts of diesel engine was investigated when it was overhauled and the followings were found:1) On the case of using emulsified fuel, the opening pressure of injection valve lowered always in comparison with using marine diesel fuel.2) Slight abnormal wear was observed at the fuel injection nozzle and pump plunger.3) Glassy white deposit and wrinkled traces which were caused by the water contained in emulsified fuel were found on the piston herd.
