Experimental Investigation of Marine Diesel Engine Performance on Testbed

Marine diesel engine in ship’ s propulsion is a very complex, high risk process that mainly determines the ship’ s mission. Therefore, its operational reliability and availability within severe sea environments, even in the case of failures or faults, should be provided. The main prerequisite for safe and reliable engine operation is good engine parameters adjustment based on proper investigation of engine dynamics in all working conditions. The most effective way for that investigation is, for sure, experimental using engine testbed with conditions very close to real ones. In the paper some experimental results of working cycles investigation of large marine diesel engine with different load conditions on testbed will be presented.
