In recent years, electronic control systems have been widely used for engines. In this paper, the autors developed a new system, using an electro-hydraulic system, and applied it to the fuel injection control and the drive control of the intake valve/exhaust valve of a medium-speed four-stroke test engine. Also, this new electro-hydraulic system was applied to the fuel injection control and the exhaust valve drive system of a large-bore, two-stroke test engine. It was confirmed that it is possible to achieve the same or higher engine performance as compared to conventional cam systems. Moreover, by combining an electronic control system of exhaust valve drive and a scavenging control valve system as a new mechanism and concept, the authors were able to control freely the scavenging and exhaust timing of an engine. As a result, the effective work of the engine was increased, and the specific fuel oil consumption was improved by 8 g/kWh.
