Sažetak
The paper elaborates a mathematical model forming the basis for a computer-simulated model for a diesel propulsion engine. The model is applied in the analysis of steady and transient operating conditions of a turbocharged slow-speed diesel propulsion engine and a fixed blade propeller. Special attention has been paid to examining the stability and availability under aggravated operating conditions such as difficulties in scavenging and turbocharging system. The analysis of the results has established ultimate limits of affecting features and has defined safe operating conditions, in particular those of the turbocharging system. The analyses and the model can be used in finding better design characteristics and in expert operating systems which can analyse different conditions of the system beforehand and offer optimum operating conditions in order to prevent unwanted occurrences.
