During the past several years we have been intereseted in and have conducted research and development on the electronic control technology of marine diesel engines.<BR>In the electronically controlled engine, the inlet valve, the exhaust valve and the fuel injection valve are driven by a hydraulically powered system. We decided to use a solenoid valve, which is superb in reliability, for the electro-hydrauslic conversion part which converts the electric signal into hydraulic oil pressure in the hydraulically powered system. We successfully developed a high-speed solenoid valve which operates in 1 msec. Then, a micro-computer based digital control system was chosen for the control equipment which plays a major role in the hydraulically powered electronic control system. An engine simulator was also developed to confirm the operation and checked the functions of the electronic control equipment. After fully confirming its relibability, the electronic control equipment was connected to an actual engine, which produced favorable operation results.<BR>This paper describes the fruit of The Technological Research Association of Highly Reliable Marine Propulsion Plant.
