Computer Aided Fuel Saving System for a Marine Diesel Engine

Abstract

The main engine fuel saving system reported here actively reduces fuel consumption during operation by controlling the fuel injection timing of the diesel engine and by making the scavenging air temperature fit for the changes of the environmental conditions at sea. It also improves the longevity and performance of the main engine by the abnormality diagnosis and the trend analysis. These functions are systematically controlled by the computer so as to respond directly to continuously changing external circumstances, and to process the relevant data. This paper describes outline of the system and intends to introduce some of the results of performance on board.
