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 abnomality diagnosis and the trend analysis. Computerised propulsion devices for vessels have been used succesfully for a long time. Their main purpose being to monitor the conditions of the main engine and to detect abnormalities. Although the system of such type enables preventive maintenance against malfunctions and fouling, it has not been able to improve fuel efficiency. The authors have developed a new control system which improves fuel consumption of marine diesel engines. A Sumitomo-Sulzer 6RLB76 engine, equipped with this system, was installed in the vessel: TSUKUBA MARU of DAIICHI CHUO KISEN KAISHIA, and is now working satisfactorily.
