電子制御システムによる舶用ディーゼル機関の高効率化 An Improvement on Performance in Marine Diesel Engines by Use of Electronic Control Systems
In recent years, an electronic-controlled system has been widely used for the engine.<BR>The authors developed a new system using hydraulic-actuated mechanisms, and applied to the fuel injection control and the drive control of the suction valve/exhaust valve of the mediumspeed four-stroke test engine.<BR>Then, it was applied to the fuel injection control system and the exhaust valve drive system of the large-sized two-stroke test engine, and it was confirmed that it is possible to achieve the same or higher engine performance as compared to the case with conventional cam system.<BR>Moreover, combining "Electronically Controlled Exhaust Valve system" and "Scavenging Controlled Valve system" as a mechanism of a new concept, the authors were able to control freely the scavenging air and exhaust timing of engine. As a result, the effective work of the engine was increased, and the specific fuel oil consumption was improved by 8g/kwh.
