電子制御ディーゼル機関運転までの経過

抄録

To reduce harmful exhaust emission from marine diesel engine, a electronic controlled hydraulic system was mounted on a medium speed 4-stroke diesel engin and applied to fuel injection and inlet/exhaust valve actuation. Monitor units were also completed to check the timings of fuel injection and inlet/exhaust valve open/close. The units showed the timing variation which was caused by electromagnetic valve motion. Improvement and adustment of the system were performed for the variation and permitted the engine operation under our directions. The progress of the engine remodeling is described in this report.
