Task 3.2: Advanced intelligent turbocharger
 

Objectives:

Two-stroke marine diesel engines: Two-stage turbocharging will be designed, manufactured and implemented to increase engine mean effective pressure up to 30 bar, with a corresponding combined cycle plant efficiency increase by 2%. With the use of the PTI/PTO unit, optimal operation conditions of the engine both with respect to emissions and fuel efficiency will be also achieved. At full load, up to 5% of the main engine shaft power can be extracted by PTO, with only very limited impact on engine SFOC and thereby, a total SFOC improvement of 2-3%.

Four-stroke marine diesel and gas engines: Two-stage turbocharging will be designed and manufactured, in order to increase boost pressure up to 8 bar. Full turbocharger control will be established by variable flow areas. A PTI facility will also be developed. With the development of this combined advanced turbocharging system, the following improvements are anticipated:

  • Gas engines: 30 bar mean effective pressure while maintaining the same heat rate.
  • Diesel engines: 30 bar mean effective pressure with at least the same fuel efficiency, where NOx emissions will improve by 50% compared to IMO limits.
