TURBO DIESEL 5 - The new simulator for maritime engineering training

The specialized diesel engine simulator named Turbo Diesel 5 is the subject of this paper. The mathematical model simulates an engine operation under various conditions and introduces various defects. This model has been implemented in a software, which is used for teaching of the relation between the diesel engine technical state and its operating parameters. The software can be also used for the maintenance strategy teaching. The most popular marine diesel engine faults like a faulty fuel injector, a leaky cylinder, a worn fuel pump, the broken piston rings, a dirty turbocharger, a dirty air filter, a dirty air cooler (and many others) were simulated. Each fault can be simulated in the certain range which can be observed in the practical operation of marine diesel engines. Not only faults, but also the improper adjustment of the fuel injection advance angle were simulated. First the single faults were simulated and their influence on the NOx emission was analyzed. The simulation research has shown that the interaction of several typical engine faults can cause the NOx emission far above the emission limit defined by IMO MARPOL convention. It has been also observed that the simulation of multiple mixed faults gives in many cases the different results that the simple multiplication of the single faults simulation.
