Abstract
The lubrication oil pressure safety and alarm system of marine diesel engines plays an important role in ensuring safe and reliable engine operation. Therefore, the operator's lack of understanding of this system will lead to economic losses and serious troubles in the engine operation. In order to improve crew training efficiency and understanding, in this article, Boolean algebra and simulation software Automation studio 5.0 were used to design and simulate this system for Daihatsu 8GK-20 diesel engine at Center Experimental Practice - Faculty of Marine Machinery, Vietnam Maritime University. The results show that the simulation system has fully simulated all functions of the real system visually and vividly. In addition, the simulation system also allows the user to perform operations to test the system's functions.
