In our capacity as a turbocharger manufacturer, the authors of the present report believe that new technologies developed specifically for low load operation will enable turbocharger performance improvement with respect to the market needs for slow steaming. Mitsubishi Heavy Industries Marine Machinery & Engine Co., LTD. (MHI-MME) has put their focus on turbocharger efficiency improvement, especially on optimizing low load efficiency, as a new generation development for Mitsubishi turbochargers. Optimized turbocharger efficiency under low load conditions will contribute to higher combustion efficiency of main propulsion engine resulting in fuel consumption reduction and minimizing the need of auxiliary blower over its operation range. Furthermore, for ships employing turbo-compound system, surplus of turbocharger improved efficiency can be used towards electrical power generation, thus enabling power turbine’s generation at load lower than ever. This can also benefit reduction of fuel used for electrical power generation at low load. Moreover, MHI-MME’s new compressor wheel with higher scavenging air pressure, wider rage, and more air flow can achieve overall turbocharger size downsizing and more applicability to main engine’s scavenging various pressure requirements. The new compressor wheel with wider range will be a remarkable fit to applications especially involving change in engine operation line during operation such as turbo-compound system and turbocharger with variable turbine inlet (VTI) for two-stroke engines. This paper introduces MHI-MME’s new technologies employed for next generation turbocharger improvement.
