Wärtsilä 46 Performance optimisation

The Wärtsilä 46 Turbocharger Performance Optimisation solution improves fuel economy by upgrading to the latest ABB TPL 73 turbocharger technology.

Upgrading to the latest compressor type improves the speed margin since the same boost pressure can be reached at a lower speed. Thermal loading is reduced because the engine exhaust gas temperature is lower. The improved efficiency and reduced thermal loading also result in lower lifecycle maintenance costs.
