Since the first turbocharged 2-cycle Diesel engine in this country was delivered as the main motor of m. s. "ARIMASAN MARU", 7 vessels are now in service, Propelled by the same type of engine which were built by Mitsui Shipbuilding and Engineering Co.In this report are given some of service results obtained from the above vessels which are connected with features of turbocharged type.The efficiency drop of the turbocharger due to fouling of turbine as well as compressor blades and guide vanes has proved of little importance during a world-round trip without overhauling or cleaning, while the effect of different sea water as well as ambient temperature on engine performances seems the same as with the case of non-turbocharged engine. No difference has been observed either on the cylinder liner wear between turbocharged and non-turbocharged engine, both of which are running on low grade fuel.
