Development and performance of diagnostic system for small marine Diesel engine functioning in dual fuel system

The paper presents the PHOTON floating laboratory of Gdansk University of Technology, equipped with a stand for testing a dual fuel (liquid and gaseous) supply system. The influence of the type of fuel on functional effects, emission, and durability of the engine is considered. Engine mooring trials of the unit were carried out to assess the influence of the used fuel on: coolant temperature, lubricating oil temperature, engine housing temperature, and engine vibration in relation to the concentration of nitrogen oxides, carbon oxides, and hydrocarbons in engine exhaust gases for dual engine supply with liquid and gaseous fuel.
