Abstract
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.
