FiTS2 stands for “Flexible integrated Turbocharging System for 2-Stroke Engines” a technology ABB Turbocharging developed in collaboration with WinG&D, a leading two-stroke engine manufacturer.
With FiTS2, operators of large marine applications running on two-stroke engines can benefit from maximum fuel savings at part and low load while maintaining highest flexibility to go to full output immediately.
FiTS2 denotes a complete, integrated turbocharging system that consists of sequential turbochargers of different specifications and wide compressor maps. As the name suggests, two or more turbochargers operate in sequence to complement each other’s air delivery at different engine loads. The turbochargers are controlled by specially developed FiTS2 tuning software, combined with dedicated, flow optimized valves that can operate under full load.
