Abstract
Availability of propulsion diesel engine such as power or any other characteristics, under different exploitation
conditions is determined by calculations, and is confirmed by empirical methods. Computer simulation models
are very important for such analyses. The computer-simulation model of ship propulsion diesel engine based on
mathematical model has been presented in the work [1].
The model is applied in the analysis of the static and dynamic operating conditions of the turbo-charged slowspeed
diesel propulsion engine and the fixed blade propeller. The model was created by applying computer program
MATLAB 7.0.4.-SIMULINK, and according the detailed mathematical zero-dimensional model.
In this paper, the aimed model is used for analyzing the influence of the power changing of one of the cylinder on
the engine performance. The power changing has been simulated by cutting of fuel delivery to one cylinder under
different loading conditions and by the different limit of fuel rack. By analyzing the results of the simulation, the limits
of engine working parameters and safety boundary conditions have been determined.
