ABB Turbocharging has announced its latest technology development, the flexible integrated turbocharging system for two-stroke engines (FiTS2) at Marintec China, December 2017.
The new sequential turbocharging system allows maximum fuel savings for two-stroke engines at part and low load, and at the same time maintains the flexibility to go to full engine output immediately. This offers significant long-term economic benefits for vessel operators and charterers with potential for fuel savings of up to 3%, depending on load profile.
FiTS2 is the result of ABB’s continued commitment to reduce fuel consumption and emissions. It has been developed in close collaboration with low-speed two-stroke engine designer, Winterthur Gas & Diesel Ltd, which has developed a special tuning for FiTS2.
The new technology enables two-stroke engine builders to offer more flexibility, increasing the potential for higher efficiency and lower operating costs for their customers. NOx emissions from engines fitted with FiTS2 will also remain within IMO Tier II limits. Additional abatement technologies like SCR or EGR can be used to comply with IMO Tier III NOx emissions and will not greatly affect the system while still delivering fuel saving benefits.
