It is likely that the demands for marine diesel engines from the shipbuilding and the shipping industries go toward the synthetic economy by improving reliability and increasing added functions rather than the reduction in fuel consumption.
In such circumstances, the authors have been engaging in the development of the engines with high flexibility and reliability which can meet the demands of clients by applying electronic control technique to each component of the engines and by constructing them as a system.
This paper will explain the whole conception of the above-mentioned system and introduce the AFR (Aut-omatic Flexible Rating) and the ALL (Automatic Cylinder liner Lubricating) control systems which has already been developed at the present.
