  • 1 Nikola Vaptsarov Naval Academy Varna, Bulgaria


In the present publication are considered the features of the dual fuel four stroke lean burn engines supercharging system operational features. The supercharging system control means are analysed and performance data is collected from an engine in operation on an offshore vessel. The data obtained from the engine in operation is analysed, processed and figures of related parameters are obtained. The latter are analysed in relation to the importance of the supercharging technical condition. Conclusions and recommendations are stated as a final outcome.
