MHI to unveil new four-stroke turbocharger series at CIMAC

The MET-ER series is to be launched into the market later in 2019 once tests with engine manufacturers are concluded.

The MET-ER Series has been developed to meet the increased ratio requirements for turbochargers to improve performance and reduce NOx emissions from four-stroke engines. The MET-ER Series can support a maximum compressor pressure ratio of 6.0, an increase on the previous MET-SCR generation of turbochargers.

The series features seven types, and a single turbocharger can handle engine outputs from 500 kW up to 5,800 kW. By rationalising the number of parts, MHI notes that the turbocharger’s footprint has been reduced, while improving the turbocharger’s “maintainability”.

The turbocharger manufacturer will also showcase its recently-launched axial flow turbocharger for two-stroke engines (MET-MBII) at the conference in Canada.

The MET-MBII series features a new compressor impeller, with an optimised blade count and blade angle distribution. The previous MET-MB series’ turbine has also been replaced with a newer model featuring an optimised distribution of turbine blades. The casing components are largely unchanged, with the exception of the silencer.
